You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.87.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 11:04, 19 October 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

Igbo Languages are spoken by a total of 31 million people.<ref name=e27/> The number of [[Igboid languages]] depends on how one classifies a language versus a [[dialect]], so there could be around 35 different Igboid languages. The core Igbo cluster or Igbo proper is generally thought to be one language but there is limited mutual intelligibility between the different groupings (north, west, south and east). A standard literary language termed 'Igbo izugbe' (meaning "general igbo") was generically developed and later adopted around 1972, with its core foundation based on the [[Orlu, Imo|Orlu]] ([[Isu people|Isu]] dialects), Anambra ([[Awka]] dialects) and [[Umuahia]] ([[Ohuhu]] dialects), omitting the [[nasal vowel|nasalization]] and [[aspiration (phonetics)|aspiration]] of those varieties.

The [[language]] was standardized in church usage by the Union Igbo Bible (1913).<ref>((cite journal |last1=Fulford |first1=Ben |title=An Igbo Esperanto: A History of the Union Ibo Bible 1900-1950 |journal=Journal of Religion in Africa |date=2002 |volume=32 |issue=4 |page=478 |doi=10.1163/157006602321107658 |jstor=1581603 |url=https://www.jstor.org/stable/1581603 |access-date=18 July 2022))</ref>

Central Igbo, is based on the dialects of two members of the Ezinifite group of Igbo in Central Owerri Province between the towns of Owerri and Umuahia in Eastern Nigeria.((citation needed|date=June 2022)) From its proposal as a literary form in 1939 by Dr. [[Ida C. Ward]], it was gradually accepted by missionaries, writers, and publishers across the region.((citation needed|date=June 2022))

Standard Igbo aims to cross-pollinate Central Igbo with words from other Igbo dialects, with the adoption of [[loan words]].<ref name=Oraka21/>

[[Chinua Achebe]] passionately denounced language standardization efforts, beginning with Union Igbo through to Central and finally Standard Igbo, in a 1999 lecture sponsored by the Roman Catholic Archdiocese in [[Owerri]].<ref>((Cite speech |title=Tomorrow is Uncertain: Today is Soon Enough |first=Chinua |last=Achebe |location=Owerri, Nigeria |date=1999 |website=Columbia University |url=http://www.columbia.edu/itc/mealac/pritchett/00fwp/igbo/achebe/index.html |archive-url=https://web.archive.org/web/20031225010722/http://www.columbia.edu/itc/mealac/pritchett/00fwp/igbo/achebe/index.html |archive-date=2003-12-25 |accessdate=23 October 2022 |translator-first=Frances W. |translator-last=Pritchett))</ref><ref>((Cite web |url=http://www.columbia.edu/itc/mealac/pritchett/00fwp/igbo/igbohistory.html |title=A History of the Igbo Language |last=Pritchett |first=Frances W. |website=Columbia University |accessdate=23 October 2022))</ref>

== Vocabulary ==

=== Word classes ===
Lexical categories in Igbo include nouns, pronouns, numerals, verbs, adjectives, conjunctions, and a single preposition.<ref name=":2">((cite book |last1=Green |first1=M. M. |last2=Igwe |first2=G. E. |year=1963 |title=A Descriptive Grammar of Igbo |publisher=Deutsche Akademie der Wissenschaften zu Berlin: Institut für Orientforschung))</ref> The meaning of ''na'', the single preposition, is flexible and must be ascertained from the context. Examples from Emenanjo (2015) illustrate the range of meaning:

((interlinear|number=(1)
|O bì '''n''''Enugwū.
|3sg live '''PREP'''-Enugwū
|'He lives '''in''' Enugwū.'))

((interlinear|number=(2)
|O bì ebe à '''n''''ogè agha.
|3sg live here this '''PREP'''-time war
|'He lived here '''during''' the time of the war.'))

((interlinear|number=(3)
|Ndị Fàda kwènyèrè '''n''''atọ̀ '''n''''ime otù.
|people Catholic believe '''PREP'''-three '''PREP'''-inside one
|'The Catholics believe in the [[Trinity]].'<ref name=":0" />))

Igbo has an extremely limited number of [[adjective]]s in a [[closed class]]. Emenanjo (1978, 2015)<ref>((cite book |last=Emenanjo |first=Nolue |year=1978 |title=Elements of Modern Igbo Grammar - a descriptive approach |location=Ibadan, Nigeria |publisher=Oxford University Press))</ref><ref name=":0">((cite book |last=Emenanjo |first=Nolue |title=A Grammar of Contemporary Igbo: Constituents, Features and Processes |location=Oxford |publisher=M and J Grand Orbit Communications |year=2015))</ref> counts just eight, which occur in pairs of opposites: ''ukwu'' 'big', ''nta'' 'small'; ''oji'' 'dark', ''ọcha'' 'light'; ''ọhụrụ'' 'new', ''ochie'' 'old'; ''ọma'' 'good'; ''ọjọọ'' 'bad' (Payne 1990).<ref>((cite encyclopedia |first=JR |last=Payne |year=1990 |title=Language Universals and Language Types |editor-last=Collinge |encyclopedia=An Encyclopedia of Language))</ref> Adjectival meaning is otherwise conveyed through the use of stative verbs or abstract nouns.

Verbs, by far the most prominent category in Igbo, host most of the language's morphology and appear to be the most basic category; many processes can derive new words from verbs, but few can derive verbs from words of other classes.<ref name=":0" />

Igbo pronouns do not index gender, and the same pronouns are used for male, female and inanimate beings. So the sentence, ''ọ maka'' can mean "he, she or it is beautiful".

== Phonology ==
===Vowels===
[[Image:Igbo vowel chart.svg|thumb|The oral vowel phonemes of Igbo, based on ((Harvcoltxt|Ikekeonwu|1999))]]
Igbo is a [[tone (linguistics)|tonal language]]. Tone varies by dialect but in most dialects there seem to be three register tones and three contour tones. The language's tone system was given by [[John Goldsmith (linguist)|John Goldsmith]] as an example of [[autosegmental]] [[Phenomenon|phenomena]] that go beyond the linear model of [[phonology]] laid out in ''[[The Sound Pattern of English]]''.<ref>((cite thesis |last=Goldsmith |first=John A. |date=June 1976 |title=Autosegmental Phonology |degree=Ph.D. |publisher=Massachusetts Institute of Technology. |url=http://www.ai.mit.edu/projects/dm/theses/goldsmith76.pdf |archive-url=https://web.archive.org/web/20050322005820/http://www.ai.mit.edu/projects/dm/theses/goldsmith76.pdf |archive-date=2005-03-22))</ref> Igbo words may differ only in tone. An example is ''ákwá'' "cry", ''àkwà'' "bed", ''àkwá'' "egg", and ''ákwà'' "cloth". As tone is not normally written, these all appear as ((angbr|akwa)) in print.

In many cases, the two (or sometimes three) tones commonly used in Igbo dictionaries fail to represent how words actually sound in the spoken language . This indicates that Igbo may have many more tones than previously recognised. For example, the imperative form of the word ''bia'' "come" has a different tone to that used in statement ''O bia'' "he came". That imperative tone is also used in the second syllable of ''abuo'' "two". Another distinct tone appears in the second syllable of ''asaa'' "seven" and another in the second syllable of ''aguu'' "hunger".
[[File:WIKITONGUES- Valentine speaking Igbo.webm|thumb|Valentine speaking Igbo.]]
The language features [[vowel harmony]] with two sets of oral vowels distinguished by [[human pharynx|pharyngeal]] cavity size described in terms of [[retracted tongue root]] (RTR). These vowels also occupy different places in vowel space: ((IPA|[i ɪ̙ e a u ʊ̙ o ɒ̙])) (the last commonly transcribed ((IPA|[ɔ̙])), in keeping with neighboring languages). For simplicity, phonemic transcriptions typically choose only one of these parameters to be distinctive, either RTR as in the chart on the right and Igbo orthography (that is, as ((IPA|/i i̙ e a u u̙ o o̙/))), or vowel space as in the alphabetic chart below (that is, as ((IPA|/i ɪ e a u ʊ o ɔ/))). There are also [[nasal vowel]]s.

Adjacent vowels usually undergo [[Assimilation (linguistics)|assimilation]] during speech. The sound of a preceding vowel, usually at the end of one word, merges in a rapid transition to the sound of the following vowel, particularly at the start of another word, giving the second vowel greater prominence in speech. Usually the first vowel (in the first word) is only slightly identifiable to listeners, usually undergoing [[Vowel reduction|centralisation]]. /kà ó mésjá/, for example, becomes /kòó mésjá/ "goodbye". An exception to this assimilation may be with words ending in /a/ such as /nà/ in /nà àlà/, "on the ground", which could be completely assimilated leaving /n/ in rapid speech, as in "nàlà" or "n'àlà". In other dialects however, the instance of /a/ such as in "nà" in /ọ́ nà èrí ńrí/, "he/she/it is eating", results in a long vowel, /ọ́ nèèrí ńrí/.<ref name="welmers74">((cite book |last=Welmers |first=William Everett |year=1974 |title=African Language Structures |publisher=University of California Press |pages=41–42 |isbn=0520022106))</ref>

===Tone===
The Igbo language is tonal in nature. This means that the meaning of a word can be altered depending on the tone used when pronouncing it. Igbo has two main tones: high and low. The high tone is usually marked with an acute accent (´) and the low tone is marked with a grave accent (`).

For example, the word ((angbr|akwa)) can mean "cry, egg, cloth, sew" depending on the tone used. If pronounced with a high tone on the first and last syllable it means "cry". But if pronounced with a low tone on the first syllable and high on the last syllable, it means "egg”. If it is pronounced with low tone on both syllables, then it will mean “cloth” or “sew”.

Another example is the word "eze” which means "king” or “teeth". If pronounced with a high tone, it means "king". But if pronounced with a low tone, it means "teeth".

The use of tonal inflection in Igbo language is very important because it helps to differentiate between words that would otherwise sound the same. It can be challenging for English speakers to learn how to use the tones properly, but with practice, it can be mastered.

===Consonants===

Igbo does not have a contrast among voiced occlusives (between voiced stops and nasals): stops precede oral vowels, and nasals precede nasal vowels. Only a limited number of other consonants occur before nasal vowels, including ((IPA|/f, z, s/)).

In some dialects, such as Enu-Onitsha Igbo, the doubly articulated ((IPA|/ɡ͡b/)) and ((IPA|/k͡p/)) are realized as a voiced/devoiced labial–velar [[implosive]]. The approximant ((IPA|/ɹ/)) is realized as an [[alveolar tap]] ((IPAblink|ɾ)) between vowels as in ''árá''. The Enu-Onitsha Igbo dialect is very much similar to Enuani spoken among the Igbo-Anioma people in Delta State.

To illustrate the effect of phonological analysis, the following inventory of a typical Central dialect is taken from Clark (1990). Nasality has been analyzed as a feature of consonants, rather than vowels, avoiding the problem of why so few consonants occur before nasal vowels; ((IPA|[CjV])) has also been analyzed as ((IPA|/CʲV/)).<ref>((cite book |first=Mary M. |last=Clark |year=1990 |title=The Tonal System of Igbo |doi=10.1515/9783110869095 |isbn=9783110130416))</ref>

Syllables are of the form ((Not a typo|(C)V)) (optional consonant, vowel) or N (a [[syllabic nasal]]). CV is the most common syllable type. Every syllable bears a tone. Consonant clusters do not occur. The semivowels ((IPAslink|j)) and ((IPAslink|w)) can occur between consonant and vowel in some syllables. The semi-vowel in ((IPA|/CjV/)) is analyzed as an underlying vowel "ị", so that ''-bịa'' is the phonemic form of ''bjá'' 'come'. On the other hand, "w" in ((IPA|/CwV/)) is analyzed as an instance of labialization; so the phonemic form of the verb ''-gwá'' "tell" is ((IPA|/-ɡʷá/)).

== Morphological typology ==
Igbo is an [[Isolating language|isolating]] language that exhibits very little [[Fusional language|fusion]]. The language is predominantly [[suffix]]ing in a hierarchical manner, such that the ordering of suffixes is governed [[Semantics|semantically]] rather than by fixed position classes. The language has very little [[inflection]]al morphology but much [[Derivational morpheme|derivational]] and extensional morphology. Most derivation takes place with verbal roots.<ref name=":0" />

Extensional suffixes, a term used in the Igbo literature, refer to morphology that has some but not all characteristics of derivation. The words created by these suffixes always belong to the same lexical category as the root from which they are created, and the suffixes' effects are principally semantic. On these grounds, Emenanjo (2015) asserts that the suffixes called extensional are bound lexical compounding elements; they cannot occur independently, though many are related to other free morphemes from which they may have originally been derived.<ref name=":0" />

In addition to affixation, Igbo exhibits both partial and full [[reduplication]] to form [[gerund]]s from verbs. The partial form copies on the initial consonant and inserts a high front vowel, while the full form copies the first consonant and vowel. Both types are then prefixed with ''o-''. For example, ''-go'' 'buy' partially reduplicates to form ''ògigo'' 'buying,' and ''-bu'' 'carry' fully reduplicates to form ''òbubu'' 'carrying'. Some other noun and verb forms also exhibit reduplication, but because the reduplicated forms are semantically unpredictable, reduplication in their case is not synchronically productive, and they are better described as separate lexical items.<ref name=":0" />

== Grammatical relations ==
Igbo does not mark overt case distinctions on nominal constituents and conveys grammatical relations only through [[word order]]. The typical Igbo sentence displays subject-verb-object (SVO) ordering, where the subject is understood as the sole argument of an intransitive verb or the agent-like (external) argument of a transitive verb. Igbo thus exhibits [[Nominative–accusative language|accusative]] [[Morphosyntactic alignment|alignment]].

It has been proposed, with reservations, that some Igbo verbs display ergativity on some level, as in the following two examples:<ref name=":0" />

((interlinear|number=(4)
|Nnukwu mmīri nà-ezò n'iro.
|big water AUX-fall PREP-outside
|'Heavy rain is falling outside.'))

((interlinear|number=(5)
|Ọ nà-ezò nnukwu mmīri n'iro.
|it AUX-fall big water PREP-outside
|'Heavy rain is falling outside.'))

In (4), the verb has a single argument, ''nnukwu mmīri'', which appears in subject position, and in the transitive sentence (5), that same argument appears in the object position, even though the two are semantically identical. On this basis, authors such as Emenanjuo (2015) have posited that this argument is an absolutive and that Igbo therefore contains some degree of ergativity.

However, others disagree, arguing that the relevant category is not alignment but underlying argument structure; under this hypothesis, (4) and (5) differ only in the application of a transformation and can be accounted for entirely by the [[Unaccusative verb|unaccusative]] hypothesis and the [[Extended Projection Principle]];<ref name=":3">((Cite journal|last=Nwachukwu|first=P. Akujuoobi |date=September 1987 |title=The Argument Structure of Igbo Verbs |journal=Lexicon Project Working Papers |volume=18 |archive-url=https://web.archive.org/web/20231221030515/https://manfredi.mayfirst.org/Nwachukwu1987MIT.pdf |archive-date=2023-12-21 |url=https://manfredi.mayfirst.org/Nwachukwu1987MIT.pdf))</ref> the nominal argument is generated in object position, and either it is raised to the subject position, as in (4), or the subject position is filled with a [[pleonastic pronoun]], as in (5).

== Relative clauses ==
Igbo relative clauses are externally headed and follow the head noun. They do not employ overt relative markers or resumptive pronouns, instead leaving a gap in the position of the relativized noun. Subjects and objects can be relativized. Examples include (relative clauses bracketed):<ref name=":0" />

((interlinear|number=(6)
|Ọ zụ̀-tà-rà àkwa [mā-ra mmā].
|3sg buy-SUFF-PRF egg [be.good-PRF goodness]
|'She bought eggs that are good.'))

((interlinear|number=(7)
|Àkwa [ọ zụ̀-tà-rà] mà-rà mmā.
|egg [3sg buy-SUFF-PRF] good-PRF goodness
|'The eggs that she bought are good.'))

== Voice and valence ==
Igbo lacks the common valence-decreasing operation of [[passivization]], a fact which has led multiple scholars to claim that "voice is not a relevant category in Igbo."<ref name=":0" /> The language does, however, possess some valence-increasing operations that could be construed as [[Voice (grammar)|voice]] under a broader definition

((interlinear|number=(8)
|Ógù a-vó-ọ-la
|Ogu PREF-be.open-SUFF-PRF
|'Ogu has become disgraced.'))

((interlinear|number=(9)
|Íbè e-mé-vọ-ọ-la Ogù.
|Ibe PREF-make-be.open-SUFF-PRF Ogu
|'Ibe has disgraced Ogu.'))

((interlinear|number=(10)
|Àfe isé kò-ro n'ezí.
|clothes five hang-PRF PREP-compound
|'Five items of clothing are hanging in the compound.'))

((interlinear|number=(11)
|Ókwu kò-we-re afe isé n'ezi.
|Okwu hang-INCH-PRF clothes five PREP-compound
|'Okwu hung five items of clothing in the compound.'))

Igbo also possess an applicative construction, which takes the suffix ''-rV'', where ''V'' copies the previous vowel, and the applicative argument follows the verb directly. The applicative suffix is identical in form with the past tense suffix, with which it should not be confused.<ref name=":2" /> For example:<ref name=":3" />

((interlinear|number=(12)
|Íbè nye-re-re m Ógù ákwụkwọ.
|Ibe give-PRF-APPL 1sg Ogu book
|'Ibe gave the book to Ogu for me.'))

== Verb serialization ==
Igbo permits [[Serial verb construction|verb serialization]], which is used extensively to compensate for its paucity of prepositions. Among the meaning types commonly expressed in serial verb constructions are instruments, datives, accompaniment, purpose, and manner. (13) and (14) below illustrate instrumental and dative verb series, respectively:<ref name=":0" />

((interlinear|number=(13)
|Ọ nà-èji mmà à-bacha jī.
|3sg AUX-PREF-use knife PREF-peel yam
|'He peels yams with a knife.'))

((interlinear|number=(14)
|Ọ zụ̀-tà-rà akwụkwọ nye m̄.
|3sg buy-SUFF-PRF book give 1sg
|'He bought a book and gave it to me.'))

=== History of Igbo orthography ===
Before the existence of any official system of orthography for the Igbo language, travelers and writers documented Igbo sounds by utilizing the orthracyologies of their own languages in transcribing them, though they encountered difficulty representing particular sounds, such as implosives, labialized velars, syllabic nasals, and non-expanded vowels. In the 1850s, German philologist [[Karl Richard Lepsius]] published the [[Standard Alphabet by Lepsius|Standard Alphabet]], which was universal to all languages of the world, and became the first Igbo orthography. It contained 34 letters and included digraphs and diacritical marks to transcribe sounds distinct to African languages.<ref name=":23">((Cite journal |last=Ohiri-Aniche |first=Chinyere |date=2007 |title=Stemming the tide of centrifugal forces in Igbo orthography |journal=Dialectical Anthropology |volume=31 |issue=4 |pages=423–436 |via=Hollis |doi=10.1007/s10624-008-9037-x |s2cid=144568449))</ref> The Lepsius Standard Alphabet contained the following letters:
* a b d e f g h i k l m n o p r s t u v w y z gb gh gw kp kw ṅ nw ny ọ s ds ts<ref name=":23"/>
The Lepsius orthography was replaced by the Practical Orthography of African Languages (Africa Orthography) in 1929 by the colonial government in Nigeria. The new orthography, created by the [[International Institute of African Languages and Culture|International Institute of African Languages and Cultures (IIALC)]], had 36 letters and disposed of diacritic marks. Numerous controversial issues with the new orthography eventually led to its replacement in the early 1960s.<ref name=":23"/> The Africa Orthography contained the following letters:
* a b c d e f g gb gh h i j k kp l m n ŋ ny o ɔ ɵ p r s t u w y z gw kw nw<ref name=":23"/>

The graphemes ((angle bracket|gb)) and ((angle bracket|kp)) are described both as coarticulated ((IPAslink|ɡ͡b)) and ((IPAslink|k͡p)) and as implosives, so both values are included in the table.

((angle bracket|m)) and ((angle bracket|n)) each represent two phonemes: a nasal consonant and a syllabic nasal.

Tones are sometimes indicated in writing, and sometimes not. When tone is indicated, low tones are shown with a grave accent over the vowel, for example ((angle bracket|a)) → ((angle bracket|à)), and high tones with an acute accent over the vowel, for example ((angle bracket|a)) → ((angle bracket|á)).

==== Other orthographies ====
A variety of issues have made agreement on a standardized [[orthography]] for the Igbo language difficult. In 1976, the Igbo Standardization Committee criticized the official orthography in light of the difficulty notating diacritic marks using typewriters and computers; difficulty in accurately representing tone with tone-marking conventions, as they are subject to change in different environments; and the inability to capture various sounds particular to certain Igbo dialects. The Committee produced a modified version of the Ọnwụ orthography, called the New Standard Orthography, which substituted ((angbr|ö)) and ((angbr|ü)) for ((angbr|ọ)) and ((angbr|ụ)), ((angbr|c)) for ((angbr|ch)), and ((angbr|ñ)) for ((angbr|ṅ)).<ref>((cite journal |last1=Oluikpe |first1=Esther N. |title=Igbo language research: Yesterday and today |journal=Language Matters |date=27 March 2014 |volume=45 |issue=1 |pages=110–126 |doi=10.1080/10228195.2013.860185|s2cid=145580712 ))</ref> The New Standard Orthography has not been widely adopted, although it was used, for example, in the 1998 ''Igbo English Dictionary'' by [[Michael Echeruo]].

More recent calls for reform have been based in part on the rogue use of alphabetic symbols, tonal notations, and spelling conventions that deviate from the standard orthography.<ref name=":23" />

There are also some modern movements to restore the use of and modernize nsibidi as a writing system,<ref>((cite web |url=http://blog.nsibiri.org/ |title=Nsibidi |website=blog.nsibiri.org))</ref><ref>((cite web |url=https://sugabellyrocks.com/2013/01/update-on-the-ndebe-igbo-writing-system.html |title=Update on the Ndebe Igbo Writing System |website=Sugabelly |date=2013-01-05))</ref> which mostly focus on Igbo as it is the most populous language that used to use nsibidi.

==== Ndebe Script ====
In 2009, a Nigerian software engineer and artist named Lotanna Igwe-Odunze developed a native script named Ndebe script. It was further redesigned and relaunched in 2020 as a standalone writing system completely independent of Nsibidi.<ref name="Tubosun">((cite web|url=http://popula.com/2020/07/13/writing-africas-future-in-new-characters|last1=Tubosun|first1=Kola|title=Writing Africa's Future in New Characters|website=Popula|date=13 July 2020))</ref><ref>((cite news |url=http://saharareporters.com/2020/07/05/nigerian-woman-lotanna-igwe-odunze-invents-new-writing-system-igbo-language |title=Nigerian Woman, Lotanna Igwe-Odunze, Invents New Writing System For Igbo Language |website=Sahara Reporters |date=2020-07-05))</ref> The script gained notable attention after a write-up from Nigerian linguist [[Kola Tubosun]] on its "straightforward" and "logical" approach to indicating tonal and dialectal variety compared to Latin.<ref name="Tubosun"/><ref>((cite news |last1=Elusoji |first1=Solomon |title=The Igbo Language Gets Its Own Modern Script, But Will It Matter? |url=https://www.channelstv.com/2020/10/03/the-igbo-language-gets-its-own-modern-script-but-will-it-matter/ |access-date=18 November 2020 |work=Channels Television |date=3 October 2020))</ref>

== Proverbs ==
[[Proverb]]s and idiomatic expressions (ilu and akpalaokwu in Igbo, respectively) are highly valued by the Igbo people and proficiency in the language means knowing how to intersperse speech with a good dose of proverbs. Chinua Achebe (in ''[[Things Fall Apart]]'') describes proverbs as "the [[palm oil]] with which words are eaten". Proverbs are widely used in the traditional society to describe, in very few words, what could have otherwise required a thousand words. Proverbs may also become euphemistic means of making certain expressions in the Igbo society, thus the Igbo have come to typically rely on this as avenues of certain expressions.<ref>((cite journal |last=Nwagbo |first=Osita Gerald |title=Sexual Taboos and Euphemisms in Igbo: An Anthropolinguistic Appraisal |journal=Language in Africa |volume=2 |issue=3 |year=2021 |pages=112–148 |doi= 10.37892/2686-8946-2021-2-3-112-148 |url=https://iling-ran.ru/library/languageinafrica/2/LiA_2_3_5_Nwagbo.pdf))</ref>

== Usage in the diaspora ==
As a consequence of the [[Atlantic slave trade]], the Igbo language was spread by enslaved Igbo people throughout slave colonies in the Americas. Examples can be found in [[Jamaican Patois]]: the pronoun ((IPA|/unu/)), used for 'you (plural)', is taken from Igbo, ''Red eboe'' refers to a fair-skinned black person because of the reported account of a fair or yellowish skin tone among the Igbo.<ref>((cite book|title=A Dictionary of Jamaican English |first1=Frederic Gomes |last1=Cassidy |edition=2nd  |first2=Robert Brock |last2=Le Page |publisher=University of the West Indies Press |year=2002 |page=168 |isbn=976-640-127-6 |url=https://books.google.com/books?id=_lmFzFgsTZYC&pg=PA168 |access-date=2008-11-24))</ref> ''Soso'' meaning ''only'' comes from Igbo.<ref>((cite book | title=The Missing Spanish Creoles: Recovering the Birth of Plantation Contact Languages | first=John H. | last=McWhorter |page=77 | isbn=0-520-21999-6 | url=https://books.google.com/books?id=czFufZI4Zx4C&pg=PA77 | publisher=University of California Press | year=2000 |access-date=2008-11-29))</ref> See [[List of Jamaican Patois words of African origin]] for more examples.

The word ''Bim'', a name for Barbados, was commonly used by enslaved [[Barbadian people|Barbadians]] ([[Barbados|Bajan]]s). This word is said to derive from the Igbo language, derived from ''bi mu'' (or either ''bem'', ''Ndi bem'', ''Nwanyi ibem'' or ''Nwoke ibem'') (((lang-en|My people))),<ref>((cite book|title=Dictionary of Caribbean English Usage |first=Richard |last=Allsopp |author2=Jeannette Allsopp |page=101 |url=https://books.google.com/books?id=PmvSk13sIc0C&pg=PA101 |publisher=University of the West Indies Press |year=2003 |others=Contributor Richard Allsopp |isbn=976-640-145-4 |access-date=2008-11-24))</ref><ref>((cite book |last=Carrington |first=Sean |title=A~Z of Barbados Heritage |year=2007 |publisher=Macmillan Caribbean Publishers Limited |pages=25 |isbn=978-0-333-92068-8<!--|access-date=2008-11-23-->))</ref> but it may have other origins (see: [[Barbados#Etymology|Barbados etymology]]).

In [[Cuba]], the Igbo language (along with the [[Efik language]]) continues to be used, albeit in a creolized form, in ceremonies of the [[Abakuá]] society, equivalent or derived from the [[Ekpe]] society in modern Nigeria.

In modern times, Igbo people in the diaspora are putting resources in place to make the study of the language accessible.

There are some discussions as to whether the Igbo language is in danger of extinction, advanced in part by a 2006 [[UNESCO]] report that predicted the Igbo language will become extinct within 50 years.<ref name=":03">((Cite journal|last=Asonye|first=Emma|date=2013|title=UNESCO Prediction of the Igbo Language Death: Facts and Fables|url=http://www.academix.ng/documents/papers/1463491669_1870.pdf|journal=Journal of the Linguistic Association of Nigeria|volume=16| issue =  1 & 2|pages=91–98))</ref> Professor of African and African Diaspora Literatures at University of Massachusetts, Chukwuma Azuonye, emphasizes indicators for the endangerment of the Igbo language based on criteria that includes the declining population of monolingual elderly speakers; reduced competence and performance among Igbo speakers, especially children; the deterioration of idioms, proverbs, and other rhetorical elements of the Igbo language that convey the cultural aesthetic; and [[code-switching]], [[code-mixing]], and [[language shift]].<ref name=":13">((Cite journal|last=Azuonye|first=Chukwuma|date=2002|title=Igbo as an Endangered Language|url=http://scholarworks.umb.edu/africana_faculty_pubs/17|journal=Africana Studies Faculty Publication Series|volume=17|pages=41–68))</ref>

External and internal factors have been proposed as causes for the decline of the Igbo language and its usage. Preference for the English language in post-colonial Nigeria has usurped the Igbo language's role and function in society,<ref name=":13" /> as English is perceived by Igbo speakers as the language of status and opportunity.<ref name=":13" /> This perception may be a contributor to the negative attitude towards the Igbo language by its speakers across the spectrum of socio-economic classes.<ref name=":03" /> Igbo children's reduced competence and performance has been attributed in part to the lack of exposure in the home environment, which impacts intergenerational transmission of the language.<ref name=":13" /> English is the official language in Nigeria and is utilized in government administration, educational institutions, and commerce. Aside from its role in numerous facets of daily life in Nigeria, globalization exerts pressure to utilize English as a universal standard language in support of economic and technological advancement.<ref name=":03" /> A 2005 study by Igboanusi and Peter demonstrated the preferential attitude towards English over the Igbo language amongst Igbo people in the communication, entertainment, and media domains. English was preferred by Igbo speakers at 56.5% for oral communication, 91.5% for written communication, 55.5–59.5% in entertainment, and 73.5–83.5% for media.<ref>((Cite journal |last=Igboanusi |first=Herbert |date=2008 |title=Is Igbo an endangered language? |url=https://www.degruyter.com/view/j/mult.2006.25.issue-4/multi.2006.023/multi.2006.023.xml |journal=Journal of Cross-Cultural and Interlanguage Communication |volume=25 |issue=4 |pages=443–452 |doi=10.1515/MULTI.2006.023|s2cid=145225091))</ref>

The effect of English on Igbo languages amongst bilingual Igbo speakers can be seen by the incorporation of English loanwords into Igbo and code-switching between the two languages. English loanwords, which are usually nouns, have been found to retain English semantics, but typically follow phonological and morphological structures of Igbo. Lexical items conform to the vowel harmony intrinsic to Igbo phonological structures. For example, loanwords with syllable-final consonants may be assimilated by the addition of a vowel after the consonant, and vowels are inserted in between consonant clusters, which have not been found to occur in Igbo.<ref name=":4" /> This can be seen in the word ''sukulu'', which is a loanword derived from the English word school that has followed the aforementioned pattern of modification when it was assimilated into the Igbo language.<ref>((Cite journal|last=Ikekeonwu|first=Clara I.|date=Winter 1982|title=Borrowings and Neologisms in Igbo|journal=Anthropological Linguistics|volume=24|issue=4|pages=480–486|jstor=30027647))</ref> Code-switching, which involves the insertion of longer English syntactic units into Igbo utterances, may consist of phrases or entire sentences, principally nouns and verbs, that may or may not follow Igbo syntactic patterns. Igbo affixes to English verbs determine tense and aspectual markers, such as the Igbo suffix -i affixed to the English word 'check', expressed as the word ''check-i''.<ref name=":4">((Cite journal|last=Akere|first=Funso|date=1981|title=Sociolinguistic consequences of language contact: English versus Nigerian Languages|journal=Language Sciences|volume=3|issue=2|pages=283–304|doi=10.1016/S0388-0001(81)80003-4))</ref>

The standardized Igbo language is composed of fragmented features from numerous Igbo dialects and is not technically a spoken language, but it is used in communicational, educational, and academic contexts. This unification is perceived by Chukwuma Azuonye as undermining the survival of Igbo by erasing diversity between dialects.<ref name=":13" /> Each individual dialect possesses unique untranslatable idioms and rhetorical devices that represent Igbo cultural nuances that can be lost as dialects disappear or deteriorate.<ref name=":13" /> Newly coined terms may fail to conform to a dialect's lexical formation in assimilating loan words.<ref name=":13" />

Proverbs are an essential component of the Igbo language that convey cultural wisdom and contextual significance to linguistic expression. Everyday usage of Igbo proverbs has declined in recent generations of speakers, which threatens loss in intergenerational transmission.<ref>((Citation|last=Emeka-Nwobia|first=Ngozi Ugo|title=Language Endangerment in Nigeria: The Resilience of Igbo Language|date=2018|work=Handbook of the Changing World Language Map|pages=1–13|editor-last=Brunn|editor-first=Stanley D|publisher=Springer International Publishing|language=en|doi=10.1007/978-3-319-73400-2_33-1|isbn=978-3-319-73400-2|s2cid=158553159|editor2-last=Kehrein|editor2-first=Roland))</ref>((citation needed|date=November 2019)) A recent study of the Ogwashi dialect of Igbo demonstrated a steep decline in youth's knowledge and use of proverbs compared to elder speakers.<ref name=":13" /> In this study, youths employed simplified or incomplete proverbial expressions, lacked a diverse proverbial repertoire, and were deficient in their understanding of proper contextual usages as compared to elders who demonstrated competence to enhance linguistic expression with a diverse vocabulary of proverbs.<ref name=":13" />
