This article summarizes grammar in the Hawaiian language.

Syntax

Hawaiian is a predominantly verb–subject–object language. However, word order is flexible, and the emphatic word can be placed first in the sentence.^[1]: p28 Hawaiian largely avoids subordinate clauses,^[1]: p.27 and often uses a possessive construction instead.^[1]: p.41 Hawaiian, unlike English, is a pro-drop language, meaning pronouns may be omitted when the meaning is clear from context.^[2]: p.108

The typical detailed word order is given by the following,^[1]: p.19 with most items optional:

1. Tense/aspect signs: i, ua, e, etc.
2. Verb
3. Qualifying adverb: mau, wale, ole, pu, etc.
4. Passive sign: ʻia
5. Verbal directives: aku, mai, etc.
6. Locatives nei or lā, or particles ana or ai
7. Strengthening particle: nō
8. Subject
9. Object or predicate noun

Exceptions to VSO word order

If the sentence has a negative mood and the subject is a pronoun, word order is subject–verb–object following the negator ʻaʻole, as in:

Another exception is when an emphatic adverbial phrase begins the sentence. In this case, a pronoun subject precedes the verb.^[1]: p.29

Interrogatives

Yes–no questions can be unmarked and expressed by intonation,^[3]: p.32 or they can be marked by placing anei after the leading word of the sentence.^[1]: p.23 Examples of question-word questions include:

Nouns

As Hawaiian does not particularly discern between word types, any verb can be nominalized by preceding it with the definite article, however, some words that are used as nouns are rarely or never used as verbs.^[1]: p.37 Within the noun phrase, adjectives follow the noun (e.g. ka hale liʻiliʻi "the house small", "the small house"), while possessors precede it (e.g. kou hale "your house"). Numerals precede the noun in the absence of the definite article, but follow the noun if the noun is preceded by the definite article.^[1]: p.31

Articles

Every noun is preceded by an article (ka‘i). The three main ones are:

• ke and ka – definitive singular – ke for words starting with letters k, e, a and o (usually memorised as ke ao "the cloud" rule) exceptions include words called nā kūʻēlula "the rule defiers" eg. ke pākaukau "the table", ke ʻō "the fork" and ke mele "the song"). For all other words ka is used.
• he – indefinite singular
• nā – plural (definite or indefinite)

Number

In noun phrases, two numbers (singular and plural) are distinguished. The singular articles ke and ka and the plural article nā are the only articles that mark number:

• ka pu‘u "the hill" vs. nā pu‘u "the hills"

In the absence of these articles, plurality is usually indicated by inserting the pluralizing particle mau immediately before the noun:

• he hale "a house" vs. he mau hale "houses"
• ko‘u hoaaloha "my friend" vs. ko‘u mau hoaaloha "my friends"

Most nouns do not change when pluralized; however, some nouns referring to people exhibit a lengthened vowel in the third syllable from the end in the plural:

• he wahine "a woman" vs. he mau wāhine "women"
• ka ‘elemakule "the old man" vs. nā ‘elemākule "the old men"
• ia kahuna "the aforementioned priest" vs. ia mau kāhuna "the aforementioned priests"

Gender

In Hawaiian, there is no gender distinction in the third person. The word for third person (he, she, it) is ia. It is commonly preceded by ʻo as in ʻo ia and, following standard modern orthographical rules, is written as two words, but it can be seen as one when written by older speakers and in historical documents.

Hawaiian nouns belong to one of two genders, this gender system is not based on biological sex and is better analyzed as a distinction between alienable and inalienable possession, which is a common split in many of the world's languages. The two genders are known as the kino ʻō (o-class) and the kino ʻā (a-class). These classes are only taken into account when using the genitive case (see table of personal pronouns below).

Kino ʻō nouns, in general, are nouns whose creation cannot be controlled by the subject, such as inoa "name", puʻuwai "heart", and hale "house". Specific categories for o-class nouns include: modes of transportation (e.g. kaʻa "car" and lio "horse"), things that you can go into, sit on or wear (e.g., lumi "room", noho "chair", ʻeke "bag", and lole "clothes"), and people in your generation (e.g., siblings, cousins) and previous generations (e.g. makuahine "mother").

Kino ʻā nouns, in general, are those whose creation can be controlled, such as waihoʻoluʻu "color", as in kaʻu waihoʻoluʻu punahele "my favorite color". Specific categories include: your boyfriend or girlfriend (ipo), spouse, friends, and future generations in your line (all of your descendants).

The change of preposition of o "of" (kino ʻō) to a "of "(kino ʻā) is especially important for prepositional and subordinate phrases^{[clarification needed]}:

• ka mea "the thing"
• kona mea "his thing (nonspecific)"
• kāna mea "his thing (which he created or somehow chose)"
• ka mea āna i ʻike ai "the thing that he saw"
• kāna (mea) i ʻike ai "what he saw"
• kēia ʻike ʻana āna "this thing that he saw (purposefully)"
• kēia ʻike ʻana ona "this thing that he saw (purportedly)" where the seeing isn't much import

Verbs

Tense, aspect, and mood

Verbs can be analytically marked with particles to indicate tense, aspect and mood. Separate verb markers are used in relative clauses, after the negation word ʻaʻole, and in some other situations.^[2]

The marker ala/lā implies greater spatial or temporal distance from the speaker than nei or ana.

In his "Introduction to Hawaiian Grammar," W.D. Alexander^[1] proposed that Hawaiian has a pluperfect tense as follows:

• ua + verb + ʻē: pluperfect tense/aspect (ua hana ʻē au "I had worked")

However, this is debatable since ʻē simply means "beforehand, in advance, already".^[4] Andrews [Gram. 1.4] suggested the same thing that Alexander forwards. However, Ua hana ʻē au could mean both "I have already worked", "I already worked", and (depending on the temporal context) "I had worked previous to that moment." "Already" is the operative unifier for these constructions as well as the perfective quality denoted by ua. ʻĒ therefore is acting like a regular Hawaiian adverb, following the verb it modifies:

• Ua hana paha au. Perhaps I worked.
• Ua hana mālie au. I worked steadily, without disruption.
• Ua hana naʻe au. I even worked.

Passive Voice

Transitive verbs can be passivized with the particle ʻia, which follows the verb but precedes tense/aspect/mood markers. The agent, if specified, is marked with the preposition e, usually translated as "by" in English:

• Ke kūkulu ʻia lā ka hale e mākou. The house is being built by us

Equative sentences

Hawaiian does not have a copula verb meaning "to be" nor does it have a verb meaning "to have". Equative sentences are used to convey this group of ideas. All equative sentences in Hawaiian are zero-tense/mood (i.e., they cannot be modified by verbal markers, particles or adverbs).

Pepeke ʻAike He "A is a B"

Pepeke ʻAike He is the name for the simple equative sentence "A is a(n) B". The pattern is "He B (ʻo) A." ʻO marks the third person singular pronoun ia (which means "he/she/it") and all proper nouns.

• He kaikamahine ʻo Mary. Mary is a girl.
• He kaikamahine ʻo ia. She is a girl.
• He Hawaiʻi kēlā kaikamahine. That girl is (a) Hawaiian.^{[clarification needed]}
• He hāumana ke keiki. The child is a student.

Pepeke ʻAike ʻO

Pepeke ʻAike ʻO is the name for the simple equative sentence "A is B." The pattern is " ʻO A (ʻo) B," where the order of the nouns is interchangeable and where ʻo invariably marks the third person singular pronoun ia and all proper nouns (regardless of where it is in the utterance).

• ʻO Mary ʻo ia. ʻO ia ʻo Mary. She is Mary.
• ʻO Mary nō ia. ʻO ia nō ʻo Mary. It's Mary.
• ʻO wau ʻo Mary. ʻO Mary wau. I'm Mary.
• ʻO ʻoe ʻo Mary. ʻO Mary ʻoe. You are Mary.
• ʻO Mary ke kaikamahine. ʻO ke kaikamahine ʻo Mary. Mary is the girl. The girl is Mary.
• ʻO ka haumana ke keiki. ʻO ke keiki ka haumana. The student is the child. The child is the student.

Pepeke Henua (Locational equative)

Pepeke Henua is the name for the simple equative sentence "A is located (in/on/at/etc. B)." The pattern is "Aia (ʻo) A..."

• Aia ʻo Mary ma Hilo. Mary is in Hilo.
• Aia ʻo ia maloko o ka wai. He/she/it is inside (of) the water.
• Aia ka haumana mahea? Aia mahea ka haumana? Where is the student?

Pepeke ʻAike Na

Pepeke ʻAike Na is the name of the simple equative sentence "A belongs to B." The pattern is "Na (B) A." The singular pronouns undergo predictable changes.

Pepeke ʻAike Na Examples:

Naʻu ke kaʻa. The car belongs to me. That's my car.

Na Mary ke keiki. The child is Mary's. It's Mary's child.

Nāna ka penikala. The pencil belongs to him/her/it.

Nāu nō au. I belong to you. I'm yours.

Note:

ʻO kēia ke kaʻa nāu. This is the car I'm giving to you.

He makana kēlā na ke aliʻi. This is a present for the chief.

Other verbal particles

Other post-verbal markers include^{[5]: pp.228–231}

• verb + mai: "toward the speaker"
• verb + aku: "away from the speaker"
• verb + iho: "down"
• verb + aʻe: "up", "adjacent"
• stative verb + iā + agent: agent marker

Causative verb creation

Causative verbs can be created from nouns and adjectives by using the prefix ho'o-, as illustrated in the following:^[3]: p.24

• nani "pretty"; hoʻonani "to beautify"
• nui "large"; hoʻonui "to enlarge"
• hui "club"; hoʻohui "to form a club"

Reduplication

Reduplication^[3]: p.23 can emphasize or otherwise alter the meaning of a word. Examples are:

• ʻau "to swim"; ʻauʻau "to bathe"
• haʻi "to say"; haʻihaʻi "to speak back and forth"
• maʻi "sick"; maʻimaʻi "chronically sick"
