Yoruba ( US : / ˈ j ɔːr ə b ə / , UK : / ˈ j ɒr ʊ b ə / ; Yor. Èdè Yorùbá , IPA: [jōrùbá] ) is a language that is spoken in West Africa , primarily in Southwestern and Central Nigeria. It is spoken by the Yoruba people . Yoruba speakers number roughly 47 million, including about 2 million second-language speakers. As a pluricentric language , it is primarily spoken in a dialectal area spanning Nigeria , Benin , and Togo with smaller migrated communities in Côte d'Ivoire , Sierra Leone and The Gambia .
55-409: Ondo State ( Yoruba : Ìpínlẹ̀ Oǹdó ) is a state in southwestern Nigeria . It was created on 3 February 1976 from the former Western State . Ondo borders Ekiti State to the north , Kogi State to the northeast for 45 km, Edo State to the east, Delta State to the southeast for 36 km, Ogun State to the southwest for 179 km, Osun State to the northwest for 77 km, and
110-402: A phoneme /n/ ; the letter ⟨n⟩ is used for the sound in the orthography, but strictly speaking, it refers to an allophone of /l/ immediately preceding a nasal vowel. There is also a syllabic nasal , which forms a syllable nucleus by itself. When it precedes a vowel, it is a velar nasal [ŋ] : n ò lọ [ŋ ò lɔ̄] 'I didn't go'. In other cases, its place of articulation
165-490: A syllable has been elided. For example: nlá 'to be large', originally a compound of ní 'to have' + lá 'to be big' and súfèé 'to whistle', originally a compound of sú 'to eject wind' + òfé or ìfé 'a blowing'. Vowels serve as nominalizing prefixes that turn a verb into a noun form. Nominal roots are mostly disyllabic , for example: abà 'crib, barn', ara 'body', ibà 'fever'. Monosyllabic and even trisyllabic roots do occur but they are less common. Yoruba
220-420: A consonant has been elided word-internally. In such cases, the tone of the elided vowel is retained: àdìrò → ààrò 'hearth'; koríko → koóko 'grass'; òtító → òótó 'truth'. Most verbal roots are monosyllabic of the phonological shape CV(N), for example: dá 'to create', dán 'to polish', pọ́n 'to be red'. Verbal roots that do not seem to follow this pattern are mostly former compounds in which
275-566: A distinction between human and non-human nouns when it comes to interrogative particles: ta ni for human nouns ('who?') and kí ni for non-human nouns ('what?'). The associative construction (covering possessive /genitive and related notions) consists of juxtaposing nouns in the order modified-modifier as in inú àpótí {inside box} 'the inside of the box', fìlà Àkàndé 'Akande's cap' or àpótí aṣọ 'box for clothes'. More than two nouns can be juxtaposed: rélùweè abẹ́ ilẹ̀ (railway underground) 'underground railway', inú àpótí aṣọ 'the inside of
330-500: A plural of respect may have prevented the coalescence of the two in NWY dialects. Central Yoruba forms a transitional area in that the lexicon has much in common with NWY and shares many ethnographical features with SEY. Its vowel system is the most traditional of the three dialect groups, retaining nine oral-vowel contrasts, six or seven nasal vowels, and an extensive vowel harmony system. Peculiar to Central and Eastern (NEY, SEY) Yoruba also
385-811: A vision received in his sleep which he believed to have been granted by Oduduwa . This Oduduwa script has also received support from other prominent chiefs in the Yorubaland region of both countries. The syllable structure of Yoruba is (C)V(N). Syllabic nasals are also possible. Every syllable bears one of the three tones: high ⟨◌́⟩ , mid ⟨◌̄⟩ (generally left unmarked), and low ⟨◌̀⟩ . The sentence n̄ ò lọ ( I didn't go ) provides examples of three syllable types: Standard Yoruba has seven oral and five nasal vowels. There are no diphthongs in Yoruba; sequences of vowels are pronounced as separate syllables. Dialects differ in
440-399: Is homorganic with the following consonant: ó ń lọ [ó ń lɔ̄] 'he is going', ó ń fò [ó ḿ fò] 'he is jumping'. C, Q, V, X and Z only appear in words borrowed from English. Yoruba is a tonal language with three-level tones and two or three contour tones. Every syllable must have at least one tone; a syllable containing a long vowel can have two tones. Tones are marked by use of
495-444: Is mi . Apart from tone's lexical and grammatical use, it is also used in other contexts such as whistling and drumming. Whistled Yoruba is used to communicate over long distances. The language is transformed as speakers talk and whistle simultaneously: consonants are devoiced or turned to [h], and all vowels are changed to [u]. However, all tones are retained without any alteration. The retention of tones enables speakers to understand

Its present monarch is HRM Oba (Dr) Oluwole Olufaderin Adetimehin, FIIN, FCIB, Jimoko II, a former President of the Chartered Insurance Institute of Nigeria who
605-490: Is a highly isolating language . Its basic constituent order is subject–verb–object , as in ó nà Adé 'he beat Adé'. The bare verb stem denotes a completed action, often called perfect; tense and aspect are marked by preverbal particles such as ń 'imperfect/present continuous', ti 'past'. Negation is expressed by a preverbal particle kò . Serial verb constructions are common, as in many other languages of West Africa . Although Yoruba has no grammatical gender , it has

The orthography here follows speech in that word divisions are normally not indicated in words that are contracted due to assimilation or elision: ra ẹja → rẹja 'buy fish'. Sometimes, however, authors may choose to use an inverted comma to indicate an elided vowel as in ní ilé → n'ílé 'in the house'. Long vowels within words usually signal that

Most modern practitioners of these religions in the Americas are not fluent in the Yoruba language, yet they still use Yoruba words and phrases for songs or chants—rooted in cultural traditions. For such practitioners,

Orthographically , ⟨ọn⟩ is used after labial and labial-velar consonants, as in ìbọn 'gun', and ⟨an⟩ is used after non-labial consonants, as in dán 'to shine'. All vowels are nasalized after the consonant /m/ , and thus there is no additional n in writing ( mi, mu, mọ ). In addition,

Like many other languages of the region, Yoruba has the voiceless and voiced labial–velar stops /k͡p/ and /ɡ͡b/ : pápá [k͡pák͡pá] 'field', gbogbo [ɡ͡bōɡ͡bō] 'all'. Notably, it lacks a voiceless bilabial stop /p/ , apart from phonaesthesia , such as [pĩpĩ] for vehicle horn sounds, and marginal segments found in recent loanwords, such as <pẹ́ńsù> [k͡pɛ́ńsù~pɛ́ńsù] for "pencil".

Standard Yoruba orthography originated in the early work of Church Mission Society missionaries working among the Aku (Yoruba) of Freetown . One of their informants was Crowther, who later would proceed to work on his native language himself. In early grammar primers and translations of portions of
1540-607: The English Bible, Crowther used the Latin alphabet largely without tone markings. The only diacritic used was a dot below certain vowels to signify their open variants [ɛ] and [ɔ] , viz. ⟨ẹ⟩ and ⟨ọ⟩ . Over the years, the orthography was revised to represent tone, among other things. In 1875, the Church Missionary Society (CMS) organized a conference on Yoruba Orthography;

The voiceless plosives /t/ and /k/ are slightly aspirated; in some Yoruba varieties, /t/ and /d/ are more dental. The rhotic consonant is realized as a flap [ɾ] or, in some varieties (notably Lagos Yoruba), as the alveolar approximant [ɹ] due to English influence. This

Linguistically, SEY has retained the /ɣ/ and /gw/ contrast, while it has lowered the nasal vowels /ĩ/ and /ʊ̃/ to /ɛ̃/ and /ɔ̃/, respectively. SEY has collapsed the second and third-person plural pronominal forms; thus, àn án wá can mean either 'you (pl.) came' or 'they came' in SEY dialects, whereas NWY for example has ẹ wá 'you (pl.) came' and wọ́n wá 'they came', respectively. The emergence of

The earliest documented history of the people, traced to the latter part of the 17th century, was in the Yoruba but in the Arabic script called Ajami . This makes Yoruba one of the oldest African languages with an attested history of Ajami (Cf. Mumin & Versteegh 2014; Hofheinz 2018). However,

Written Yoruba includes diacritical marks not available on conventional computer keyboards, requiring some adaptations. In particular, the use of the sub dots and tone marks are not represented, so many Yoruba documents simply omit them. Asubiaro Toluwase, in his 2014 paper, points out that
2145-649: The most widely spoken African language outside of the continent. There is a substantial body of literature in the Yoruba language, including books, newspapers, and pamphlets. Yoruba is used in radio and television broadcasting and is taught at primary, secondary, and tertiary levels. The Yoruba dialect continuum consists of several dialects. The various Yoruba dialects in Yorubaland can be classified into five major dialect areas: Northwest, Northeast, Central, Southwest, and Southeast. Clear boundaries cannot be drawn, but peripheral areas of dialectal regions often have some similarities to adjoining dialects. North-West Yoruba

There are several items of Yoruba Ajami in poetry, personal notes, and esoteric knowledge (Cf. Bang 2019). Nevertheless, Yoruba Ajami remained idiosyncratic and not socially diffused, as no standardized orthography existed. The plethora of dialects and the absence of a central promotional institution, among others, are responsible. In
