Russian grammar employs an Indo-European inflexional structure, with considerable adaptation.

Russian has a highly inflectional morphology, particularly in nominals (nouns, pronouns, adjectives and numerals). Russian literary syntax is a combination of a Church Slavonic heritage, a variety of loaned and adopted constructs, and a standardized vernacular foundation.

The spoken language has been influenced by the literary one, with some additional characteristic forms. Russian dialects show various non-standard grammatical features, some of which are archaisms or descendants of old forms discarded by the literary language.

Various terms are used to describe Russian grammar with the meaning they have in standard Russian discussions of historical grammar, as opposed to the meaning they have in descriptions of the English language; in particular, aorist, imperfect, etc., are considered verbal tenses, rather than aspects, because ancient examples of them are attested for both perfective and imperfective verbs. Russian also places the accusative case between the dative and the instrumental, and in the tables below, the accusative case appears between the nominative and genitive cases.

Nouns

Nominal declension involves six main cases – nominative, genitive, dative, accusative, instrumental, and prepositional – in two numbers (singular and plural), and grammatical gender (masculine, feminine, and neuter). Up to ten additional cases are identified in linguistics textbooks,^[1][2][3] although all of them are either incomplete (do not apply to all nouns) or degenerate (appear identical to one of the six main cases) – the most recognized additional cases are locative, partitive and vocative. Old Russian also had a third number, the dual, but it has been lost except for its use in the nominative and accusative cases with the numbers two, three, and four (e.g. два стула, "two chairs"), where it is now reanalyzed as genitive singular.

More often than in many other Indo-European languages, Russian noun cases may supplant the use of prepositions entirely.^[4] Furthermore, every preposition is exclusively used with a particular case (or cases). Their usage can be summarised as:^[5]

• nominative (имени́тельный):
  • main subject;
  • default case to use outside sentences (dictionary entries, signs, etc.);
  • prepositions: за '(what) kind of?'; в: 'join the ranks of' (with plural nouns only);
• accusative (вини́тельный):
  • direct object;
  • some time expressions;
  • prepositions indicating motion: в 'into, in(ward)', на 'onto (the top of)', за 'behind, after', под 'under';
  • other prepositions: про 'about', через 'over, through', сквозь 'through';
• genitive (роди́тельный):
  • possession – 'of' (genitive noun);
  • numerals and quantifiers;
  • negated verbs (which take direct objects in Accusative) to indicate total absence;
  • some time expressions;
  • prepositions: без 'without', вместо 'instead of', возле 'near', вокруг 'around', впереди 'ahead of', для 'for', до 'before', из 'from', из-за 'because of, from behind', от 'from', кроме 'except for', мимо 'past by', около 'near', после 'after', против 'against, opposite', среди 'among', у 'by', близ 'near', вдоль 'along', вне 'out of, outside', внутри 'inside';
  • verbs: бояться 'afraid of', достигать 'reach', избегать 'avoid';
  • adjectives: полный 'full of' (genitive noun);
• dative (да́тельный):
  • indirect object – 'to' (dative noun);
  • some time expressions;
  • impersonal clauses: мне холодно – 'I am cold', lit. "to_me (is) cold";
  • age statements: мне двадцать лет – 'I am 20 (years old)', lit. 'to_me (is) 20 years';
  • prepositions: по 'on', к 'to(wards)', благодаря 'thanks to';
  • auxiliaries: нужно or надо 'need/must (to)', можно 'allowed', нельзя 'forbidden';
  • verbs: верить 'believe', помочь 'help', советовать 'advise', звонить 'call', удивить(ся) 'amaze (self)';
• instrumental (твори́тельный):
  • instrument used in the action or means by which action is carried out – 'by' (I. noun);
  • logical subject of passive clause: письмо написано Иваном – 'the letter was written by Ivan';
  • secondary direct object: его считают студентом – 'he is considered (to be) a student';
  • durational time expressions;
  • verbs: интересовать(ся) 'interest (to be interested in)', пользоваться 'use', занимать(ся) 'occupy (to be preoccupied with)';
  • associates of connective verbs: быть 'be', стать 'became', остаться 'remain', казаться 'appear to be', оказаться 'turn out to be';
  • prepositions of position: за 'behind', перед 'in front of', над 'above', под 'below', между 'between', (вместе) с '(together) with';
  • adjective: довольный 'pleased by';
• prepositional (предло́жный):
  • prepositions of place: в 'inside', на 'on (top of)';
  • other prepositions: о 'about', при 'by/of/with';

Definite and indefinite articles (corresponding to 'the', 'a', 'an' in English) do not exist in the Russian language. The sense conveyed by such articles can be determined in Russian by context. However, Russian also utilizes other means of expressing whether a noun is definite or indefinite:

• The use of a direct object in the genitive instead of the accusative in negation signifies that the noun is indefinite, compare: Я не ви́жу кни́ги ("I don't see a book" or "I don't see any books") and Я не ви́жу кни́гу ("I don't see the book").
• The same goes for certain verbs expressing a desire to achieve something: wait, wish, ask, want, etc. When the inanimate object is definite (certain, or at least expected), the accusative is used; when it is indefinite (uncertain), the genitive is used. Compare: Я жду автобус ("I'm waiting for the bus", а specific, scheduled bus) and Я жду автобуса ("I'm waiting for a bus", any bus, if one will come).^[6]
• The use of the numeral one sometimes signifies that the noun is indefinite, e.g.: Почему́ ты так до́лго? – Да так, встре́тил одного́ дру́га, пришло́сь поговори́ть ("Why did you take so long?" – "Well, I met one [=a] friend and had to talk").
• Word order may also be used for this purpose; compare В ко́мнату вбежа́л ма́льчик ("Into the room rushed a boy") and Ма́льчик вбежа́л в ко́мнату ("The boy rushed into the room").
• The plural form may signify indefiniteness: Вы мо́жете купи́ть э́то в магази́нах ("You can buy this in shops") vs. Вы мо́жете купи́ть э́то в магази́не ("You can buy this in the shop").

The category of animacy is relevant in Russian nominal and adjectival declension.^[7] Specifically, the accusative has two possible forms in many paradigms, depending on the animacy of the referent. For animate referents (persons and animals), the accusative form is generally identical to the genitive form. For inanimate referents, the accusative form is identical to the nominative form. This principle is relevant for masculine singular nouns of the second declension (see below) and adjectives, and for all plural paradigms (with no gender distinction). In the tables below, this behavior is indicated by the abbreviation 'N or G' in the row corresponding to the accusative case.

Russian uses three declensions:^[8]

• The first declension is used for feminine nouns ending with -а/-я and some masculine nouns having the same form as those of feminine gender, such as па́па (papa) or дя́дя (uncle); also, common-gender nouns like зади́ра (bully) are masculine or feminine depending on the person to which they refer.
• The second declension is used for most masculine and neuter nouns.
• The third declension is used for feminine nouns ending in ь.

A group of irregular "different-declension nouns" (Russian: разносклоняемые существительные), consists of a few neuter nouns ending in -мя (e.g. время "time") and one masculine noun путь "way". However, these nouns and their forms have sufficient similarity with feminine third declension nouns that scholars such as Litnevskaya^[9] consider them to be non-feminine forms of this declension.

Nouns ending with -ий, -ия, -ие (not to be confused with nominalized adjectives) are written with -ии instead of -ие in prepositional (as this ending is never stressed, there is no difference in pronunciation): тече́ние – в ни́жнем тече́нии реки́ "streaming – in lower streaming of a river". However, if words в течение and в продолжение represent a compound preposition meaning – "while, during the time of" – they are written with -е: в тече́ние ча́са "in a time of an hour". For nouns ending in -ья, -ье, or -ьё, using -ьи in the prepositional (where endings of some of them are stressed) is usually erroneous, but in poetic speech it may be acceptable (as we replace -ии with -ьи for metric or rhyming purposes): Весь день она́ лежа́ла в забытьи́ (Fyodor Tyutchev).

First declension

Feminine and masculine nouns ending with а or я vowel

Second declension

Masculine nouns ending with a consonant sound

Some singular nouns denoting groups of people may include the -ин- suffix before ending.

Neuter nouns

Third declension

Feminine nouns ending with letter ь

Neuter nouns ending with мя

Indeclinable nouns

Some nouns (such as borrowings from other languages, abbreviations, etc.) are not modified when they change number and case. This occurs especially when the ending appears not to match any declension pattern in the appropriate gender. An example of an indeclinable noun is кофе ("coffee").

Additional cases

Some nouns use several additional cases. The most important of these are:

• Locative (ме́стный): the most common minor case, used with some nouns after the prepositions of location на and в(о). With most nouns, the prepositional form is used in such instances. When there is a distinct locative, it takes the form of the dative ending but with the ending necessarily stressed. A few feminine nouns ending in ь have a locative form of independent origin, consisting of the singular genitive/dative/prepositional ending but with the ending necessarily stressed. This may mean it matches the dative, or it may take a unique form. For example, in во рту́ ("in the mouth") and в груди́ ("in the chest"), the locatives of рот ("mouth") and грудь match the dative forms ртy and (modern) груди́. In the case of рот, this differs from the prepositional ртe, but in the case of грудь the prepositional (and all other singular oblique cases besides instrumental) have merged with the locative. In в лесу́ ("in the forest") and в связи́ ("in view (of)"), the locatives of лес ("forest") and связь ("link, connection") differ from both the prepositional ле́се and свя́зи and the dative ле́сy and свя́зи (the dative and locative of лес are spelt identically but pronounced differently).
• Partitive (отдели́тельный), or second genitive: sometimes used instead of the accusative (as it should be for the direct object) to imply, that only part of the object is affected by the verb: налить ча́ю "to pour some tea" (not all the tea) — from налить чай "to pour the tea". It is never final-stressed.
• Vocative (зва́тельный): used to call or speak to a person. There are two types of vocative in modern Russian. The common Slavic vocative is archaic and survives only in fixed expressions: Бо́же мой! (My God!). The modern vocative (sometimes called neo-vocative) is produced from a first-declension noun by removing the vowel ending: мам, ты меня слышишь? "mom, can you hear me?" from ма́ма. It can only be applied to familiar (affectionate) terms for family members or close friends and diminutives of commonly used Slavic names: Ива́н (full name) — Ва́ня (short, affectionate) — Вань (neo-vocative); Мари́я — Ма́ша — Маш. It is frequently used in the informal spoken language with a certain number of nouns in the plural: "ребя́т, пойдёмте!" ("guys, let's go!") from ребя́та, "девча́т, смотри́те!" ("girls, look!") from девча́та.
• Caritive (лиши́тельный), often used with the negation of verbs: не знать пра́вды (not to know the truth) — знать пра́вду (to know the truth). This case is identical to the genitive and obligatory replaces the accusative for all negated forms of the verb быть "to be", including compound verbs: Меня не было дома "I wasn't home" — compare Я был дома "I was home"; Этого не может быть! "It can't be!" — compare Это может быть (так) "It (This) can be (so)" (however: Это не может быть правдой "This can't be true" is the only correct option). Some negated verbs are allowed to be used with caritive in a casual speech, if considered synonymous with "to be" (существовать "to exist", случиться "to happen", появиться "to appear"). For many other verbs use of caritive may be considered illiterate: Вас тут не стояло "You were not standing here" — compare Вы тут не стояли (same, but with proper use of the accusative).

Adjectives

A Russian adjective (и́мя прилага́тельное) is usually placed before the noun it qualifies, and it agrees with the noun in case, gender, and number. With the exception of a few invariant forms borrowed from other languages, such as беж ('beige', non-adapted form of бе́жевый) or ха́ки ('khaki-colored'), most adjectives follow one of a small number of regular declension patterns (except for some that complicate the short form). In modern Russian, the short form appears only in the nominative and is used when the adjective is in a predicative role: нов, нова́, нóво, новы́ are short forms of но́вый ('new'). Formerly (as in the bylinas) short adjectives appeared in all other forms and roles, which are not used in the modern language, but are nonetheless understandable to Russian speakers as they are declined exactly like nouns of the corresponding gender.^[10]

Adjectives may be divided into three general groups:

• qualitative (ка́чественные) – denote a quality of the object; this is the only group that usually has degrees of comparison.
• relational (относи́тельные) – denote some sort of relationship; unlikely to act as a predicate or have a short form.
• possessive (притяжа́тельные) – denote belonging to a specific subject; have some declensional peculiarities.

Adjectival declension

The pattern described below holds true for full forms of most adjectives, except possessive ones. It is also used for substantivized adjectives as учёный ("scientist, scholar" as a noun substitute or "scientific, learned" as a general adjective) and for adjectival participles. Russian differentiates between hard-stem and soft-stem adjectives, shown before and after a slash sign.

• The masculine and neuter genitive singular adjectival endings -ого and -его are pronounced as -ово and -ево.
• After a sibilant (ш, ж, ч, щ) or velar (к, г, х) consonant, и is written instead of ы.
• When a masculine adjective ends in -ой in the nominative, the stress falls on the final syllable throughout its declension: прямо́й ([prʲɪˈmoj], "straight"), compare упря́мый ([ʊˈprʲamɨj], "stubborn").
• The "хоро́шее rule" states that after a sibilant consonant, neuter adjectives end in -ее.
• The masculine accusative singular and the accusative plural endings depend on animacy, as with nouns.
• The instrumental feminine ending -ой/-ей has old-fashion alternative form -ою/-ею for all adjectives, which has only a stylistic difference.
• There are often stress changes in the short form. For example, the short forms of но́вый ("new") are нов (m.), но́во (n.), нова́ (f.), новы́/но́вы (pl.).
• In the masculine singular short form, when a word-final consonant cluster is being formed after ending removal, an additional е or о interfix is inserted after the root, as in го́лоден, from голо́дный ("hungry").
• Some adjectives (e.g. большо́й "big", ру́сский "Russian") have no short forms.

Comparison of adjectives

Comparison forms are usual only for qualitative adjectives and adverbs. Comparative and superlative synthetic forms are not part of the paradigm of original adjective but are different lexical items, since not all qualitative adjectives have them. A few adjectives have irregular forms that are declined as usual adjectives: большо́й 'big' – бо́льший 'bigger', хоро́ший 'good' – лу́чший 'better'. Most synthetically-derived comparative forms are derived by adding the suffix -е́е or -е́й to the adjective stem: кра́сный 'red' – красне́е 'redder'; these forms are difficult to distinguish from adverbs, whose comparative forms often coincide with those of their adjectival counterparts.^[10] Superlative synthetic forms are derived by adding the suffix -е́йш- or -а́йш- and additionally sometimes the prefix наи-, or using a special comparative form with the prefix наи-: до́брый 'kind' – добре́йший 'the kindest', большо́й 'big' – наибо́льший 'the biggest'.

An alternative is to add an adverb to the positive form of the adjective. The adverbs used for this are бо́лее 'more' / ме́нее 'less' and са́мый 'most' / наибо́лее 'most' / наиме́нее 'least': for example, до́брый 'kind' – бо́лее до́брый 'kinder' – са́мый до́брый 'the kindest'. This way is rarely used if special comparative forms exist.

Possessive adjectives

Possessive adjectives are less frequently used in Russian than in most other Slavic languages,^[11] but are in use. They respond to the questions чей? чья? чьё? чьи? (whose?) and denote only animate possessors. See section below.

Pronouns

Personal pronouns

• Russian is subject to the T–V distinction. The respectful form of the singular you is the same as the plural form. It begins with a capital letter: Вы, Вас, Вам, etc., in the following situations: personal letters and official papers (addressee is definite), and questionnaires (addressee is indefinite); otherwise it begins with minuscule. Compare the distinction between du and Sie in German or tu and vous in French.
• When a preposition is used directly before a third-person pronoun, it is prefixed with н-: у него (read: у нево), с неё, etc. Because the prepositional case always occurs after a preposition, the third person prepositional always starts with an н-.
• There are special cases for prepositions before first person singular pronouns: со мной – "with me" (usually с), ко мне – "to me" (usually к), во мне – "in me" (usually в), обо мне – "about me" (usually о). All of these preposition forms are unstressed.
• Like adjectives and numerals, letter "г" (g) in masculine and neuter 3rd person genitive and accusative forms is pronounced as "в" (v): (н)его – (н)ево.
• English "it" can be translated as both оно́ (neuter personal pronoun) and э́то (neuter proximal demonstrative, "this"). The latter is used as a stub pronoun for a subject: э́то хорошо́ – "it/this is good", кто́ это? – "who is it/this?".

Demonstrative pronouns

If the preposition "about" is used (usually о), for singular demonstrative pronouns (as with any other words starting with a vowel) it is об: об э́том – about this.

Possessive adjectives and pronouns

Unlike English, Russian uses the same form for a possessive adjective and the corresponding possessive pronoun. In Russian grammar they are called possessive pronouns притяжательные местоимения (compare with possessive adjectives like Peter's = Петин above). The following rules apply:

• Possessive pronouns agree with the noun of the possessed in case, gender, and number.
• The reflexive pronoun свой is used when the possessor is the subject of the clause, whatever the person, gender, and number of that subject.
• No non-reflexive exists for the third person: the genitive of the personal pronoun is instead, i.e. его for a masculine/neuter singular possessor, её for a feminine singular possessor and их for a plural possessor. But unlike other genitives used with a possessive meaning, in modern Russian these words are usually placed before the object of possession.
• Example of the difference between reflexive and non-reflexive pronouns:
  • "Он лю́бит свою́ жену́ = He loves his (own) wife"   while   "Он лю́бит его́ жену́ = He loves his (someone else's) wife".
• Unlike Latin where a similar rule applies for the third person only, Russian accepts using reflexives for all persons:
  • "Я люблю́ (свою́) жену́ = I love my wife"
  • "Я люблю́ себя́ = I love myself"

The ending -его is pronounced as -ево́.

Interrogative pronouns

These interrogatives are used by scholars to denote "usual" questions for correspondent grammatical cases (prepositional is used with о): (кто?) Ма́ша лю́бит (кого?) Ва́сю – (who?) Masha [N.] loves (whom?) Vasya [G.].

The ending "-его" is pronounced as "-ево".

Numerals

Russian has several classes of numerals ([имена] числительные): cardinal, ordinal, collective, and also fractional constructions; also it has other types of words, relative to numbers: collective adverbial forms (вдвоём), multiplicative (двойной) and counting-system (двоичный) adjectives, some numeric-pronominal and indefinite quantity words (сколько, много, несколько). Here are the numerals from 0 to 10:

Verbs

Grammatical conjugation is subject to three persons in two numbers and two simple tenses (present/future and past), with periphrastic forms for the future and subjunctive, as well as imperative forms and present/past participles, distinguished by adjectival and adverbial usage (see adjectival participle and adverbial participle). Verbs and participles can be reflexive, i.e. have reflexive suffix -ся/-сь appended after ending.

The past tense is made to agree in gender with the subject, for it is the participle in an originally periphrastic perfect formed (like the perfect passive tense in Latin) with the present tense of the verb "to be" быть [bɨtʲ], which is now omitted except for rare archaic effect, usually in set phrases (откуда есть пошла земля русская [ɐtˈkudə jesʲtʲ pɐˈʂla zʲɪˈmlʲa ˈruskəjə], "whence is come the Russian land", the opening of the Primary Chronicle in modern spelling). The participle nature of past-tense forms is exposed also in that they often have an extra suffix vowel, which is absent in present/future; the same vowel appears in infinitive form, which is considered by few scholars not to be verbal (and in the past it surely used to be a noun), but in which verbs appear in most dictionaries: ходить "to walk" – ходил "(he) walked" – хожу "I walk".

Verbal inflection is considerably simpler than in Old Russian. The ancient aorist, imperfect, and (periphrastic) pluperfect have been lost, though the aorist sporadically occurs in secular literature as late as the second half of the eighteenth century, and survives as an odd form in direct narration (а он пойди да скажи [ɐ on pɐjˈdʲi də skɐˈʐɨ], etc., exactly equivalent to the English colloquial "so he goes and says"), recategorized as a usage of the imperative. The loss of three of the former six tenses has been offset by the development, as in other Slavic languages, of verbal aspect (вид). Most verbs come in pairs, one with imperfective (несоверше́нный вид) or continuous, the other with perfective (соверше́нный вид) or completed aspect, usually formed with a (prepositional) prefix, but occasionally using a different root. E.g., спать [spatʲ] ('to sleep') is imperfective; поспать [pɐˈspatʲ] ('to take a nap') is perfective.

The present tense of the verb быть is today normally used only in the third-person singular form, есть, which is often used for all the persons and numbers.^[13] As late as the nineteenth century, the full conjugation, which today is extremely archaic, was somewhat more natural: forms occur in the Synodal Bible, in Dostoevsky and in the bylinas (былины [bɨˈlʲinɨ]) or oral folk-epics, which were transcribed at that time. The paradigm shows as well as anything else the Indo-European affinity of Russian:

Infinitive

The infinitive is the basic form of a verb for most purposes of study. In Russian it has the suffix -ть/-ти (the latter is used after consonants), or ends with -чь (but -чь is not a suffix of a verb). For reflexive verbs -ся/-сь suffix is added in the end. Note that due to phonological effects, both -ться and -тся endings (latter is used for present-future tense of a 3rd person reflexive verb; see below) are pronounced as [t͡sə] or [tsə] and often cause misspellings even among native speakers.

Present-future tense

Future tense has two forms: simple and compound.

• Future simple forms are formed by perfective verbs with the help of personal endings: "She will read" (She will have read) — "Она́ прочита́ет/прочтёт"; "She will do some reading" (She will be reading [for a certain amount of time]) — "Она́ почита́ет".
• Future compound forms are formed by imperfective verbs: a future simple tense form of the verb "быть" (to be) and the infinitive of an imperfective verb. The Russian compound future tense is similar in structure to the English future progressive tense and is used to indicate that something will be in progress at a particular moment in the future: She will be reading — "Она́ бу́дет чита́ть", without any assurance that an action will be completed, as opposed to using a perfective verb to refer to an action that is expected to be completed in the future: "Она́ прочтёт" — "She will read / She will have read".

• -у/-ут,-ат is used after a hard consonant or ж, ш, щ or ч; otherwise -ю/-ют,-ят is used.
• A mutating final consonant may entail a change in the ending.
• е becomes ё when stressed.

Two forms are used to conjugate the present tense of imperfective verbs and the future tense of perfective verbs.

The first conjugation is used in verb stems ending in:

• a consonant,
• -у,-ы or -о,-я
• -е (In addition to below)
• Бить, пить, жить, шить, лить, вить, гнить, брить, стелить, зиждить.
• -а not preceded by a hush (ж, ш, щ or ч):

The second conjugation involves verb stems ending in:

• -и or -е (Глядеть, смотреть, видеть, ненавидеть, обидеть, зависеть, терпеть, вертеть, пыхтеть, сидеть, лететь, гудеть, гореть, сопеть, дудеть, блестеть, храпеть, смердеть, хрипеть, шелестеть, хрустеть, сипеть, кишеть, бдеть, звенеть, кряхтеть, кипеть, корпеть, зудеть, скорбеть, тарахтеть, шуметь, зреть, висеть, греметь, шипеть)
• -а preceded by a hush (ж, ш, щ or ч)(Слышать, дышать, держать, лежать, дребезжать, жужжать, брюзжать, дрожать, бренчать, стучать, мычать, кричать, молчать, рычать, мчать, урчать, звучать, бурчать, ворчать, торчать, журчать, гнать):
• Стоять, бояться

Example: попро-с-ить – попро-ш-у, попро-с-ят [pəprɐˈsʲitʲ, pəprɐˈʂu, pɐˈprosʲɪt] (to have solicited – [I, they] will have solicited).

Examples

There are five irregular verbs:

• бежа́ть (run), бре́зжить (glimmer) – first conjugation in the plural third person, second in other forms;
• хоте́ть (want) – first conjugation in the singular, second in plural;
• дать (give) – дам, дашь, даст, дади́м, дади́те, даду́т;
• есть (eat) – ем, ешь, ест, еди́м, еди́те, едя́т.

Past tense

The Russian past tense is gender specific: –л for masculine singular subjects, –ла for feminine singular subjects, –ло for neuter singular subjects, and –ли for plural subjects. This gender specificity applies to all persons; thus, to say "I slept", a male speaker would say я спал, while a female speaker would say я спалá.

Examples

Exceptions

Moods

Russian verbs can form three moods (наклонения): indicative (изъявительное), conditional (сослагательное) and imperative (повелительное).^[14]

Imperative mood

The imperative mood second-person singular is formed from the future-present base of most verbs by adding -и (stressed ending in present-future, or if base ends on more than one consonant), -ь (unstressed ending, base on one consonant) or -й (unstressed ending, base on vowel). Plural (including polite на вы) second-person form is made by adding -те to singular one: говорю 'I speak' – говори – говорите, забуду 'I shall forget' – забудь – забудьте, клею 'I glue' – клей – клейте. Some perfective verbs have first-person plural imperative form with -те added to similar simple future or present tense form: пойдёмте 'let us go'. Other forms can express command in Russian; for third person, for example, пусть particle with future can be used: Пусть они замолчат! 'Let them shut up!'.^[15]

Conditional mood

The conditional mood in Russian is formed by adding the particle бы after the word which marks the supposed subject into a sentence formed like in the past tense. Thus, to say "I would (hypothetically) sleep" or "I would like to sleep", a male speaker would say я спал бы (or я бы поспа́л), while a female speaker would say я спалá бы (or я бы поспала́).

Verbs of motion

Verbs of motion are a distinct class of verbs found in several Slavic languages. Due to the extensive semantic information they contain, Russian verbs of motion pose difficulties for non-native learners at all levels of study.^[16] Unprefixed verbs of motion, which are all imperfective, divide into pairs based on the direction of the movement (uni- or multidirectional — sometimes referred to as determinate/indeterminate or definite/indefinite). As opposed to a verb-framed language, in which path is encoded in the verb, but manner of motion typically is expressed with complements, Russian is a satellite language, meaning that these concepts are encoded in both the root of the verb and the particles associated with it, satellites.^[17] Thus, the roots of motion verbs convey the lexical information of manner of movement, e.g. walking, crawling, running, whereas prefixes denote path, e.g. motion in and out of space.^{[18][note 1]} The roots also distinguish between means of conveyance, e.g. by transport or by one's own power, and in transitive verbs, the object or person being transported.^[19] The information below provides an outline of the formation and basic usage of unprefixed and prefixed verbs of motion.

Unprefixed

Directionality

Unidirectional verbs describe motion in progress in one direction, e.g.:

• We are headed to the library.
  Мы идём в библиотеку.
• I was on my way to work.
  Я шла на работу.
• The birds are flying south.
  Птицы летят на юг.

Multidirectional verbs describe:

1. General motion, referring to ability or habitual motion, without reference to direction or destination, e.g.:
   • The child has been walking for six months.
     Ребёнок ходит шесть месяцев.
   • Birds fly, fish swim, and dogs walk.
     Птицы летают, рыбы плавают, а собаки ходят.
2. Movement in various directions, e.g.:
   • We walked around the city all day.
     Мы ходили по городу весь день.
3. Repetition of completed trips, e.g.:
   • She goes to the supermarket every week.
     Она ходит в супермаркет каждую неделю.
4. In the past tense, a single completed round trip, e.g.:
   • I went to Russia (and returned) last year.
     В прошлом году я ездил в Россию.

Unidirectional perfectives with по-

The addition of the prefix по- to a unidirectional verb of motion makes the verb perfective, denoting the beginning of a movement, i.e. 'setting out'. These perfectives imply that the agent has not yet returned at the moment of speech, e.g.,^{[20]: 353–355}

Going versus taking

Three pairs of motion verbs generally refer to 'taking', 'leading' with additional lexical information on manner of motion and object of transport encoded in the verb stem. These are нести/носить, вести/водить, and везти/возить. See below for the specific information on manner and object of transport:^[20]

Prefixed motion verbs

Motion verbs combine with prefixes to form new aspectual pairs, which lose the distinction of directionality, but gain spatial or temporal meanings. The unidirectional verb serves as the base for the perfective, and the multidirectional as the base for the imperfective. In addition to the meanings conveyed by the prefix and the simplex motion verb, prepositional phrases also contribute to the expression of path in Russian.^[21] Thus, it is important to consider the whole verb phrase when examining verbs of motion.

In some verbs of motion, adding a prefix requires a different stem shape:^[22]

See below for a table the prefixes, their primary meanings, and the prepositions that accompany them, adapted from Muravyova.^[19] Several examples are taken directly or modified from Muravyova.

Idiomatic uses

The uni- and multidirectional distinction rarely figures into the metaphorical and idiomatic use of motion verbs, because such phrases typically call for one or the other verb. See below for examples:^{[20]: 357–358}

Adjectival participle

Russian adjectival participles can be active or passive; have perfective or imperfective aspect; imperfective participles can have present or past tense, while perfective ones in classical language can be only past.^[23] As adjectives, they are declined by case, number and gender. If adjectival participles are derived from reciprocal verbs, they have suffix -ся appended after the adjectival ending; this suffix in participles never takes the short form. Participles are often difficult to distinguish from deverbal adjectives (this is important for some cases of orthography).

Active present participle

Лю́ди, живу́щие в э́том го́роде, о́чень до́брые и отве́тственные – The people living in this city are very kind and responsible.

In order to form the active present participle, the "т" of the 3rd person plural of the present tense is replaced by "щ", and a necessary adjective ending is added:

Note: Only imperfective verbs can have an active present participle.

(*) Note: These forms are obsolete in modern Russian and they are not used in the spoken language as forms of the verb 'to be'.

Reflexive verbs paradigm

The participle agrees in gender, case and number with the word it refers to:

Я посвяща́ю э́ту пе́сню лю́дям, живу́щим в на́шем го́роде – I dedicate this song to the people living in our city.

Я горжу́сь людьми́, живу́щими в на́шем го́роде – I'm proud of the people living in our city.

Active past participle

The active past participle is used in order to indicate actions that happened in the past:

Де́вушка, чита́вшая тут кни́гу, забы́ла свой телефо́н – The girl, that read this book here, forgot her phone (the girl read the book in the past).

Compare:

Де́вушка, чита́ющая тут кни́гу, – моя́ сестра́ – The girl reading this book here is my sister (she is reading the book now, in the present).

In order to form the active past participle the infinitive ending '-ть' is replaced by the suffix '-вш-' and add an adjective ending:

Reflexive verbs paradigm

Passive present participle

обсужда́ть – to discuss;

обсужда́емый (full form), обсужда́ем (short form) – being discussed or able to be discussed;

In order to form the passive present participle it is necessary to add an adjective ending to the 1st person plural of the present tense:

Passive participles are occasional in modern Russian. Often, same meaning is conveyed by reflexive active present participles:

рису́ющийся (self-drawing) instead of рису́емый (being drawn, drawable);

мо́ющийся (self-washing) instead of мо́емый (being washed);

The forms ending in -омый are mostly obsolete. Only the forms ведо́мый (from вести́ – to lead) and иско́мый (from иска́ть – to search, to look for) are used in the spoken language as adjectives:

ведо́мый челове́к – a slave (driven, following) man;

иско́мая величина́ – the sought quantity.

Passive past participle

сде́лать – to do/to make (perfective verb)

сде́ланный – done/made

Passive past participles are formed by means of the suffixes '-нн-' or '-т-' from the infinitive stem of perfective verbs. Besides that, this kind of participle can have short forms formed by means of the suffixes '-н-' or '-т-':

Adverbial participle

Adverbial participles (деепричастия) express an earlier or simultaneous action providing context for the sentence in which they occur, similar to the English constructions "having done X" or "while doing Y".

Like normal adverbs, adverbial participles are not declined. They inherit the aspect of their verb; imperfective ones are usually present, while perfective ones can only be past (since they denote action performed by the subject, the tense corresponds to the time of action denoted by the verb). Almost all Russian adverbial participles are active, but passive constructions may be formed using adverbial participle forms of the verb быть (past бывши "having been", present будучи "being"); these may be combined with either an adjectival participle in the instrumental case (Будучи раненным, боец оставался в строю – Being wounded, the combatant remained in the row), or a short adjective in the nominative (Бывши один раз наказан, он больше так не делал – Having been punished once, he didn't do it any more).

Present adverbial participles are formed by adding the suffix -а/-я (or sometimes -учи/-ючи, which is usually deprecated) to the stem of the present tense. A few past adverbial participles (mainly of intransitive verbs of motion) are formed in the same way, but most are formed with the suffix -в (alternative form -вши, always used before -сь), some whose stem ends with a consonant, with -ши. For reflexive verbs, the suffix -сь remains at the very end of the word; in poetry it can take the form -ся.^[24][25]

In standard Russian, adverbial participles are considered a feature of bookish speech; in colloquial language they are usually replaced with single adjectival participles or constructions with verbs: Пообедав, я пошёл гулять ("Having eaten, I went for a walk") → Я пообедал и пошёл гулять ("I had dinner and went for a walk"). But in some dated dialects adverbial and adjectival participles may be used to produce perfect forms which sound illiterate and do not occur in modern Russian; e.g. "I haven't eaten today" will be "Я сегодня не евши" instead of "Я сегодня не ел".

Irregular verbs

¹These verbs all have a stem change.
²These verbs are palatalised in certain cases, namely с → ш for all the present forms of "писа́ть", and д → ж in the first person singular of the other verbs.
³These verbs do not conform to either the first or second conjugations.

Word formation

Russian has on hand a set of prefixes, prepositional and adverbial in nature, as well as diminutive, augmentative, and frequentative suffixes. All of these can be stacked one upon the other to produce multiple derivatives of a given word. Participles and other inflectional forms may also have a special connotation. For example:

Russian has also proven friendly to agglutinative compounds. As an extreme case:

Purists (as Dmitry Ushakov in the preface to his dictionary) frown on such words. But here is the name of a street in St. Petersburg:

Some linguists have suggested that Russian agglutination stems from Church Slavonic. In the twentieth century, abbreviated components appeared in the compound:

Syntax

Basic word order, both in conversation and written language, is subject–verb–object. However, because grammatical relationships are marked by inflection, considerable latitude in word order is allowed, and all possible permutations can be used. For example, the words in the phrase "я пошёл в магазин" ('I went to the shop') can be arranged:

• Я пошёл в магазин. (I went to the shop; I went to the shop.)
• Я в магазин пошёл. (I to the shop went; approx. I am going out, my destination is the shop.)
• Пошёл я в магазин. (Went I to the shop; two meanings: can be treated as a beginning of a narrated story: "Went I to the shop, and something happened." or a decision made by someone after a long contemplation: "OK, I think I will go the shop.")
• Пошёл в магазин я. (Went to the shop I; rarely used, can be treated as a beginning of a line of a poem written in amphibrach due to uncommon word order, or when the speaker wants to highlight that exactly this subject "went to the shop". In that case, the subject is stressed)
• В магазин я пошёл. (To the shop I went; two meanings: can be used as a response: "I went to the shop." – "Sorry, where did you go?" – "To the shop—that's where I went." or an emphasis on the way of transportation: I went to the shop on foot.)
• В магазин пошёл я. (To the shop went I; It was me who went to the shop.)

while maintaining grammatical correctness. Note, however, that the order of the phrase "в магазин" ("to the shop") is kept constant.

Word order can express logical stress, and degree of definiteness. The primary emphasis tends to be initial, with a weaker emphasis at the end. Some of these arrangements can describe present actions, not only past (despite the fact that the verb пошёл is in the past).

In some cases, alternative word order can change the meaning entirely:

• Не надо меня уговаривать. ("No need me [to] persuade" → One should not persuade me [as I would never agree to do something].)
• Меня не надо уговаривать. ("Me no need [to] persuade" → There is no need to persuade me [as I will do it anyway].)

Impersonal sentences

Russian is a null-subject language – it allows constructing sentences without subject (Russian: безличные предложения). Some of them are claimed to not be impersonal, but to have oblique subject. One possible classification of such sentences distinguishes:^[27]

Subjectless impersonals contain an impersonal verb (in form of single third-person or single neutral), and no other word is used as a subject

Смеркалось. '(It got) dusky.'

В Москве полночь. '(It's) midnight in Moscow.'

Dative impersonals usually express personal feelings, where experiencer in dative case can possibly be considered as subject

Мне^dat. скучно. 'I'm bored.'

Other impersonals have an element which is neither nominative nor dative, but still is a nominal verb argument

Меня^acc. тошнит. 'I feel sick.'

Васю^acc. ударило током^instr.. 'Vasya had an electric shock.'

Negation

Multiple Negatives

Unlike in standard English, multiple negatives are compulsory in Russian, as in "никто никогда никому ничего не прощает" [nʲɪkˈto nʲɪkɐɡˈda nʲɪkɐˈmu nʲɪtɕɪˈvo nʲɪ prɐɕˈɕæjɪt] ('No-one ever forgives anyone for anything' literally, "no one never to no-one nothing does not forgive"). Usually, only one word in a sentence has negative particle or prefix "не" or belongs to negative word "нет", while another word has negation-affirmative particle or prefix "ни"; but this word can often be omitted, and thus ни becomes the signal of negation: вокруг никого нет and вокруг никого both mean "there is nobody around".

Adverbial answers

As a one-word answer to an affirmative sentence, yes translates да and no translates нет, as shown by the table below.^{[citation needed]}

No simple rule supplies an adverbial answer to a negative sentence. B. Comrie^[28] says that in Russian answer да or нет is determined not so much by the negative form of the question as by the questioner's intent for using negation, or whether the response is in agreement with his presupposition. In many cases that means that the adverbial answer should be extended for avoiding ambiguity; in spoken language, intonation in saying нет can also be significant to if it is affirmation of negation or negation of negation.

Note that while expressing an affirmation of negation by extending "да" with a negated verb is grammatically acceptable. In practice it is more common to answer "нет" and subsequently extend with a negated verb paralleling the usage in English. Answering a negative sentence with a non-extended "нет" is usually interpreted as an affirmation of negation again in a way similar to English.

Alternatively, both positive and negative simple questions can be answered by repeating the predicate with or without не, especially if да/нет is ambiguous: in the latest example, "сержусь" or "не сержусь".

Coordination

The most common types of coordination expressed by compound sentences in Russian are conjoining, oppositional, and separative. Additionally, the Russian grammar considers comparative, complemental, and clarifying. Other flavors of meaning may also be distinguished.

Conjoining coordinations are formed with the help of the conjunctions и "and", ни … ни ("not … not" — simultaneous negation), та́кже "also", то́же ("too"; the latter two have complementary flavors), etc. Most commonly the conjoining coordination expresses enumeration, simultaneity or immediate sequence. They may also have a cause-effect flavor.

Oppositional coordinations are formed with the help of the oppositional conjunctions: а "and"~"but", но "but", одна́ко "however", зато́ "on the other hand", же "and"~"but", etc. They express the semantic relations of opposition, comparison, incompatibility, restriction, or compensation.

Separative coordinations are formed with the help of the separative conjunctions: и́ли "or", ли́бо "either", ли … ли "whether … or", то … то "then … then", etc. They express alternation or incompatibility of things expressed in the coordinated sentences.

Complemental and clarifying coordination expresses additional, but not subordinated, information related to the first sentence.

Comparative coordination is a semantic flavor of the oppositional one.

Common coordinating conjunctions include:

• и [i] "and", enumerative, complemental;
• а [a] "and", comparative, tending to "but" or "while";
• но [no] "but", oppositional.

The distinction between "и" and "а" is important:

• "и" implies a following complemental state that does not oppose the antecedent;
• "а" implies a following state that acts in opposition to the antecedent, but more weakly than "но" ("but").

The distinction between "и" and "а" developed after medieval times. Originally, "и" and "а" were closer in meaning. The unpunctuated ending of the Song of Igor illustrates the potential confusion. The final five words in modern spelling, "князьям слава а дружине аминь" [knʲɪˈzʲjam ˈslavə ɐ druˈʐɨnʲɪ ɐˈmʲinʲ] can be understood either as "Glory to the princes and to their retinue! Amen." or "Glory to the princes, and amen (R.I.P.) to their retinue". Although the majority opinion is definitely with the first interpretation, no consensus has formed. The psychological difference between the two is quite obvious.

Subordination

Complementizers (subordinating conjunctions, adverbs, or adverbial phrases) include:

• если [ˈjesʲlʲɪ] 'if' (meaning 'in case where' not meaning 'whether');
• потому что [pətɐˈmu ʂtə] 'because'
• так как [tak kak] 'since' (meaning 'for the reason that')
• чтобы [ˈʂtobɨ], дабы [ˈdabɨ] (bookish, archaic) 'so that'
• после того, как [ˈposʲlʲɪ tɐˈvo kək] 'after'
• хотя [xɐˈtʲa] 'although'

In general, Russian has fewer subordinate clauses than English, because the participles and adverbial participles often take the place of a relative pronoun/verb combination. For example:

Absolute construction

Despite the inflectional nature of Russian, there is no equivalent in modern Russian to the English nominative absolute or the Latin ablative absolute construction. The old language had an absolute construction, with the noun in the dative. Like so many other archaisms, it is retained in Church Slavonic. Among the last known examples in literary Russian occurs in Radishchev's Journey from Petersburg to Moscow (Путешествие из Петербурга в Москву [pʊtʲɪˈʂɛstvʲɪje ɪs pʲɪtʲɪrˈburɡə v mɐˈskvu]), 1790:

Едущу мне из Едрова, Анюта из мысли моей не выходила. [ˈjedʊɕːʉ mnʲe ɪzʲ jɪˈdrovə, ɐˈnʲutə ɪz ˈmɨsʲlʲɪ mɐˈjej nʲɪ vɨxɐˈdʲilə] "As I was leaving Yedrovo village, I could not stop thinking about Aniuta."
