Oromo, also known as Afaan borana Oromoo, Oromiffa(a) (Ethiopic: ኦሮሚኛ), and sometimes in other languages by variant spellings of these names (Oromic, Afan Oromo, etc.), is an Afro-Asiatic language, and the most widely spoken of the Cushitic family. It is spoken as a first language by more than 35 million Oromo and neighboring peoples in Ethiopia and Kenya. After their subjugation by the Abyssinians (Habesha people), their language and people were referred to by Abyssinians as well as by misinformed Europeans as Galla, but this term is no longer recognized in a modern context.
At least 99 percent of Oromo speakers live in Ethiopia, mainly in Oromia Region. In Somalia there are also about 42,000 speakers of the language.
Within Ethiopia, Oromo is the first most spoken (more than 40%). Within Africa, it is the language with the fourth most speakers, after Arabic (if one counts the mutually unintelligible spoken forms of Arabic as a single language and assuming the same for the varieties of Oromo), Swahili, Hausa.
Besides first language speakers, a number of members of other ethnicities who are in contact with the Oromos speak Oromo as a second language, for example, the Omotic-speaking Bambassi and the Nilo-Saharan-speaking Kwama in northwestern Oromia.
Before the Ethiopian Revolution of 1974, publishing or broadcasting in Oromo was prohibited, and the few works that had been published, most notably Onesimos Nesib's and Aster Ganno's translation of the Bible from the late nineteenth century, were written in the Ge'ez script. Following the 1974 Revolution, the government undertook a literacy campaign in several languages, including Oromo, and publishing and radio broadcasts began in the language. All Oromo materials printed in Ethiopia at that time, such as the newspaper Barissa, were written in the traditional script.
Plans to introduce Oromo instruction in the schools, however, were not realized until the government of Mengistu Haile Mariam was overthrown in 1991, except in regions controlled by the Oromo Liberation Front. With the creation of Oromia under the new system of ethnic regions, it has been possible to introduce Oromo as the medium of instruction in elementary schools throughout the region (including areas where other ethnic groups live speaking their languages) and as a language of administration within the region.
Oromo is most commonly written with a modified Latin alphabet called Qubee, which was formally adopted in 1991, and used by the Oromo Liberation Front rebels by the late 1970's. In recent years, it is said to have been limited by the Ethiopian government.
With the adoption of Qubee, it is believed more texts were written in the Oromo language between 1991 and 1997 than in the previous 100 years.
The Saphalo script was an indigenous Oromo script invented by Sheikh Bakri Saphalo (also known by his birth name, Abubaker Usman Odaa) in the years following Italian invasion of Ethiopia, and used underground afterwards . The Arabic alphabet has also been used intermittently in areas with Muslim populations.
Within Kenya there has been radio broadcasting in Oromo (in the Borana dialect) on the Voice of Kenya since at least the 1980s. The Borana Bible in Kenya was printed using the Latin alphabet, but not using the same spelling rules as in Ethiopian Qubee.
Sounds and orthography
Consonant and vowel phonemes
Like most other Ethiopian languages, whether Semitic, Cushitic, or Omotic, Oromo has a set of ejective consonants
, that is, voiceless stops or affricates that are accompanied by glottalization and an explosive burst of air. Oromo has another glottalized phone that is more unusual, an implosive
retroflex stop, "dh" in Oromo orthography, a sound that is like an English "d" produced with the tongue curled back slightly and with the air drawn in so that a glottal stop is heard before the following vowel begins.
Oromo has the typical Southern Cushitic set of five short and five long vowels, indicated in the orthography by doubling the five vowel letters. The difference in length is contrastive, for example, hara 'lake', haaraa 'new'. Gemination is also significant in Oromo. That is, consonant length can distinguish words from one another, for example, badaa 'bad', baddaa 'highland'.
In the Qunee alphabet, a single "letter" consists either of a single symbol or a digraph ("ch", "dh", "ny", "ph", "sh"). Gemination is not obligatorily marked for the digraphs, though some writers indicate it by doubling the first symbol: qopphaa'uu 'be prepared'. In the charts below, the International Phonetic Alphabet symbol for a phoneme is shown in brackets where it differs from the Oromo letter. The phonemes /p/, /v/ and /z/ appear in parentheses because they are only found in recent loan words. Note that there have been minor changes in the orthography since it was first adopted: "x" (IPA [t']) was originally represented as "th", and there has been some confusion among authors in the use of "c" and "ch" in representing the phonemes /ʧ'/ and /ʧ/, with some early works using "c" for /ʧ/ and "ch" for /ʧ'/ and even "c" for different phonemes depending on where it appears in a word. This article uses "c" consistently for /ʧ'/ and "ch" for /ʧ/.

Like most other Afro-Asiatic languages
, Oromo has two grammatical genders
masculine and feminine, and all nouns belong to either one or the other.
Grammatical gender in Oromo enters into the grammar in the following ways:
- Verbs (except for the copula be) agree with their subjects in gender when the subject is third person singular (he or she).
- Third person singular personal pronouns (he, she, it, etc. in English) have the gender of the noun they refer to.
- Adjectives agree with the nouns they modify in gender.
- Some possessive adjectives ("my", "your") agree with the nouns they modify in some dialects.
Except in some southern dialects, there is nothing in the form of most nouns that indicates their gender. A small number of nouns pairs for people, however, end in -eessa (m.) and -eettii (f.), as do adjectives when they are used as nouns: obboleessa 'brother', obboleettii 'sister', dureessa 'the rich one (m.)', hiyyeettii 'the poor one (f.)'. Grammatical gender normally agrees with biological gender for people and animals; thus nouns such as abbaa 'father', ilma 'son', and sangaa 'ox' are masculine, while nouns such as haadha 'mother' and intala 'girl, daughter' are feminine. However, most names for animals do not specify biological gender.
Names of astronomical bodies are feminine: aduu 'sun', urjii 'star'. The gender of other inanimate nouns varies somewhat among dialects.
Oromo has singular and plural number
, but nouns that refer to multiple entities are not obligatorily plural. That is, if the context is clear, a formally singular noun may refer to multiple entities: nama
'man', nama shan
, 'five men'. Another way of looking at this is to treat the "singular" form as unspecified for number.
When it is important to make the plurality of a referent clear, the plural form of a noun is used. Noun plurals are formed through the addition of suffixes. The most common plural suffix is -oota; a final vowel is dropped before the suffix, and in the western dialects, the suffix becomes -ota following a syllable with a long vowel: mana 'house', manoota 'houses', hiriyaa 'friend', hiriyoota 'friends', barsiisaa 'teacher', barsiiso(o)ta 'teachers'. Among the other common plural suffixes are -(w)wan, -een, and -(a)an; the latter two may cause a preceding consonant to be doubled: waggaa 'year', waggaawwan 'years', laga 'river', laggeen 'rivers', ilma 'son', ilmaan 'sons'.
Oromo has no indefinite articles
(corresponding to English a
), but (except in the southern dialects) it indicates definiteness
) with suffixes on the noun: -(t)icha
for masculine nouns (the ch
is geminated though this is not normally indicated in writing) and -(t)ittii
for feminine nouns. Vowel endings of nouns are dropped before these suffixes: karaa
'the road', nama
'the man', haroo
'the lake'. Note that for animate nouns that can take either gender, the definite suffix may indicate the intended gender: qaalluu
'the priest (m.)', qallittii
'the priest (f.)'. The definite suffixes appear to be used less often than the
in English, and they seem not to co-occur with the plural suffixes.
An Oromo noun has a citation form
or base form
that is used when the noun is the object of a verb, the object of a preposition or postposition, or a nominal predicative
- mana 'house', mana binne 'we bought a house'
- hamma 'until', dhuma 'end', hamma dhuma 'until (the) end'
- mana keessa, 'inside (a/the) house'
- inni 'he', barsiisaa 'teacher', inni barsiisaa (dha) 'he is a teacher'
A noun may also appear in one of six other grammatical cases, each indicated by a suffix or the lengthening of the noun's final vowel. The case endings follow plural or definite suffixes if these appear. For some of the cases, there is a range of forms possible, some covering more than one case, and the differences in meaning among these alternatives may be quite subtle. Nominative
- The nominative is used for nouns that are the subjects of clauses.
- * Ibsaa man's name, Ibsaan 'Ibsaa (nom.)', makiinaa, qaba 'he has', Ibsaan makiinaa qaba 'Ibsaa has a car'
- Most nouns ending in short vowels with a preceding single consonant drop the final vowel and add -ni to form the nominative. Following certain consonants, assimilation changes either the n or that consonant (the details depend on the dialect).
- * nama 'man', namni 'man (nom.)'
- * namoota 'men'; namootni, namoonni 'men (nom.)' (t + n may assimilate to nn)
- If a final short vowel is preceded by two consonants or a geminated consonant, -i is suffixed.
- * ibsa 'statement', ibsi 'statement (nom.)'
- * namicha 'the man', namichi 'the man (nom.)' (the ch in the definite suffix -icha is actually geminated, though not normally written as such)
- If the noun ends in a long vowel, -n is suffixed to this. This pattern applies to infinitives, which end in -uu.
- * maqaa 'name', maqaan 'name (nom.)'
- * nyachuu 'to eat, eating', nyachuun 'to eat, eating (nom.)'
- If the noun ends in n, the nominative is identical to the base form.
- * afaan 'mouth, language (base form or nom.)'
- Some feminine nouns ending in a short vowel add -ti. Again assimilation occurs in some cases.
- * haadha 'mother', haati (dh + t assimilates to t)
- * lafa 'earth', lafti Genitive
- The genitive is used for possession or "belonging"; it corresponds roughly to English of or -'s. The genitive is usually formed by lengthening a final short vowel, by adding -ii to a final consonant, and by leaving a final long vowel unchanged. The possessor noun follows the possessed noun in a genitive phrase. Many such phrases with specific technical meanings have been added to the Oromo lexicon in recent years.
- * obboleetti 'sister', namicha 'the man', obboleetti namichaa 'the man's sister'
- * hojii 'job', Caaltuu, woman's name, hojii Caaltuu, 'Caaltuu's job'
- * barumsa 'field of study', afaan 'mouth, language', barumsa afaanii 'linguistics'
- In place of the genitive it is also possible to use the relative marker kan (m.) / tan (f.) preceding the possessor.
- * obboleetti kan namicha 'the man's sister' Dative
- The dative is used for nouns that represent the recipient (to) or the benefactor (for) of an event. The dative form of a verb infinitive (which acts like a noun in Oromo) indicates purpose. The dative takes one of the following forms:
- * Lengthening of a final short vowel (ambiguously also signifying the genitive)
- * namicha 'the man', namichaa 'to the man, of the man'
- * -f following a long vowel or a lengthened short vowel; -iif following a consonant
- * intala 'girl, daughter', intalaaf 'to a girl, daughter'
- * saree 'dog', sareef 'to a dog'
- * baruu 'to learn', baruuf 'in order to learn'
- * bishaan 'water', bishaaniif 'for water'
- * -dhaa or -dhaaf following a long vowel
- * saree 'dog'; sareedhaa, sareedhaaf 'to a dog'
- * -tti (with no change to a preceding vowel), especially with verbs of speaking
- * Caaltuu woman's name, himi 'tell, say (imperative)', Caaltuutti himi 'tell Caaltuu' Instrumental
- The instrumental is used for nouns that represent the instrument ("with"), the means ("by"), the agent ("by"), the reason, or the time of an event. The formation of the instrumental parallels that of the dative to some extent:
- * -n following a long vowel or a lengthened short vowel; -iin following a consonant
- * harka 'hand', harkaan 'by hand, with a hand'
- * halkan 'night', halkaniin 'at night'
- * -tiin following a long vowel or a lengthened short vowel
- * Afaan Oromoo 'Oromo (language)', Afaan Oromootiin 'in Oromo'
- * -dhaan following a long vowel
- * yeroo 'time', yeroodhaan 'on time'
- * bawuu 'to come out, coming out', bawuudhaan 'by coming out' Locative
- The locative is used for nouns that represent general locations of events or states, roughly at. For more specific locations, Oromo uses prepositions or postpositions. Postpositions may also take the locative suffix. The locative also seems to overlap somewhat with the instrumental, sometimes having a temporal function. The locative is formed with the suffix -tti.
- * Arsiitti 'in Arsii'
- * harka 'hand', harkatti 'in hand'
- * guyyaa 'day', guyyaatti 'per day'
- * jala, jalatti 'under' Ablative
- The ablative is to represent the source of an event; it corresponds closely to English from. The ablative, applied to postpositions and locative adverbs as well a nouns proper, is formed in the following ways:
- * When the word ends in a short vowel, this vowel is lengthened (as for the genitive).
- * biyya 'country', biyyaa 'from country'
- * keessa 'inside, in', keessaa 'from inside'
- * When the word ends in a long vowel, -dhaa is added (as for one alternative for the dative).
- * Finfinneedhaa 'from Finfinnee (Addis Ababa)'
- * gabaa 'market', gabaadhaa 'from market'
- * When the word ends in a consonant, -ii is added (as for the genitive).
- * Hararii 'from Harar'
- * Following a noun in the genitive, -tii is added.
- * mana 'house', buna 'coffee', mana bunaa 'cafe', mana bunaatii 'from cafe'
- An alternative to the ablative is the postposition irraa 'from' whose initial vowel may be dropped in the process:
- * gabaa 'market', gabaa irraa, gabaarraa 'from market'
In most languages, there is a small number of basic distinctions of person
, and often gender
that play a role within the grammar of the language.
Oromo and English are such languages. We see these distinctions within the basic set of independent personal pronouns
, for example,
, Oromo ani
; English they
, Oromo isaani
and the set of
, for example, English my
, Oromo koo
; English mine
, Oromo kan koo
In Oromo, the same distinctions are also reflected in subject-verb agreement:
Oromo verbs (with a few exceptions) agree
with their subjects
; that is, the person, number, and (singular third person) gender of the subject of the verb are marked by suffixes
on the verb. Because these suffixes vary greatly with the particular verb tense
, they are normally not considered to be pronouns and are discussed elsewhere in this article under verb conjugation
In all of these areas of the grammar — independent pronouns, possessive adjectives, possessive pronouns, and subject-verb agreement — Oromo distinguishes seven combinations of person, number, and gender.
For first and second persons, there is a two-way distinction between singular ('I', 'you sg.') and plural ('we', 'you pl.'), whereas for third person, there is a two-way distinction in the singular ('he', 'she') and a single form for the plural ('they'). Because Oromo has only two genders, there is no pronoun corresponding to English it; the masculine or feminine pronoun is used according to the gender of the noun referred to.
Oromo is a subject pro-drop language.
That is, neutral sentences in which the subject is not emphasized do not require independent subject pronouns: kaleessa dhufne 'we came yesterday'.
The Oromo word that translates 'we' does not appear in this sentence, though the person and number are marked on the verb dhufne ('we came') by the suffix -ne.
When the subject in such sentences needs to be given prominence for some reason, an independent pronoun can be used: nuti kaleessa dhufne 'we came yesterday'.
The table below gives forms of the personal pronouns in the different cases, as well as the possessive adjectives. For the first person plural and third person singular feminine categories, there is considerable variation across dialects; only some of the possibilities are shown.
The possessive adjectives, treated as separate words here, are sometimes written as noun suffixes. In most dialects there is a distinction between masculine and feminine possessive adjectives for first and second person (the form agreeing with the gender of the modified noun). However, in the western dialects, the masculine forms (those beginning with k-) are used in all cases. Possessive adjectives may take the case endings for the nouns they modify: ganda kootti 'to my village' (-tti: locative case).

As in languages such as French, Russian, and Turkish, the Oromo second person plural is also used as a polite singular form, for reference to people that the speaker wishes to show respect towards. This usage is an example of the so-called T-V distinction that is made in many languages. In addition, the third person plural may be used for polite reference to a single third person (either 'he' or 'she').
For possessive pronouns ('mine', 'yours', etc.), Oromo adds the possessive adjectives to kan 'of': kan koo 'mine', kan kee 'yours', etc.
Reflexive and reciprocal pronouns
Oromo has two ways of expressing reflexive pronouns
('myself', 'yourself', etc.). One is to use the noun meaning 'self': of(i)
. This noun is inflected for case but, unless it is being emphasized, not for person, number, or gender: isheen of laalti
'she looks at herself' (base form of of
), isheen ofiif makiinaa bitte
'she bought herself a car' (dative of of
The other possibility is to use the noun meaning 'head', mataa, with possessive suffixes: mataa koo 'myself', mataa kee 'yourself (s.)', etc.
Oromo has a reciprocal pronoun wal (English 'each other') that is used like of/if. That is, it is inflected for case but not person, number, or gender: wal jaalatu 'they like each other' (base form of wal), kennaa walii bidan 'they brought each other gifts' (dative of wal).
Like English, Oromo makes a two-way distinction between proximal ('this, these') and distal ('that, those') demonstrative pronouns
and adjectives. Some dialects distinguish masculine and feminine for the proximal pronouns; in the western dialects the masculine forms (beginning with k-
) are used for both genders. Unlike in English, singular and plural demonstratives are not distinguished, but, as for nouns and personal pronouns in the language, case is distinguished. Only the base and nominative forms are shown in the table below; the other cases are formed from the base form as for nouns, for example, sanatti
'at/on/in that' (locative case).
Oromo Demonstrative Pronouns
| san |
| suni |
An Oromo verb consists minimally of a stem
, representing the lexical
meaning of the verb, and a suffix
, representing tense
agreement. For example, in dhufne
'we came', dhuf-
is the stem ('come') and -ne
indicates that the tense is past and that the subject of the verb is first person plural.
As in many other Afro-Asiatic languages, Oromo makes a basic two-way distinction in its verb system between the two tensed forms, past (or "perfect") and present (or "imperfect" or "non-past"). Each of these has its own set of tense/agreement suffixes. There is a third conjugation based on the present which has three functions: it is used in place of the present in subordinate clauses, for the jussive ('let me/us/him, etc. V', together with the particle haa), and for the negative of the present (together with the particle hin). For example, deemne 'we went', deemna 'we go', akka deemnu 'that we go', haa deemnu 'let's go', hin deemnu 'we don't go'. There is also a separate imperative form: deemi 'go (sg.)!'.
The table below shows the conjugation in the affirmative and negative of the verb beek-
'know'. The first person singular present and past affirmative forms require the suffix -n
to appear on the word preceding the verb or the word nan
before the verb. The negative particle hin
, shown as a separate word in the table, is sometimes written as a prefix on the verb.

For verbs with stems ending in certain consonants and suffixes beginning with consonants (that is, t or n), there are predictable changes to one or the other of the consonants. The dialects vary a lot in the details, but the following changes are common.
|b- + -t → bd
|| qabda 'you (sg.) have' |
| g- + -t → gd
|| dhugda 'you (sg.) drink' |
| r- + -n → rr
|| barra 'we learn' |
| l- + -n → ll
|| galla 'we enter' |
| q- + -t → qx
|| dhaqxa 'you (sg.) go' |
| s- + -t → ft
|| baas- 'take out', baafta 'you (sg.) take out' |
| s- + -n → fn
|| baas- 'take out', baafna 'we take out' |
| t-/d-/dh-/x- + -n → nn
|| bitti 'buy', binna 'we buy'; nyaadhaa 'eat', nyaanna 'we eat' |
| d- + -t → dd
|| fid- 'bring', fidda 'you (sg.) bring' |
| dh- + -t → tt
|| taphadh- 'play', taphatta 'you (sg.) play' |
| x- + -t → xx
|| fix- 'finish', fixxa 'you (sg.) finish' |
Verbs whose stems end in two consonants and whose suffix begins with a consonant must insert a vowel to break up the consonants since the language does not permit sequences of three consonants. There are two ways this can happen: either the vowel i
is inserted between the stem and the suffix, or the final stem consonants are switched (an example of metathesis
) and the vowel a
is inserted between them. For example, arg-
'he sees', argina
'we see'; kolf-
'he laughed', kolfite
'you (sg.) laughed'.
Verbs whose stems end in the consonant ' (which may appear as h, w, or y in some words, depending on the dialect) belong to three different conjugation classes; the class is not predictable from the verb stem. It is the forms that precede suffixes beginning with consonants (t and n) that differ from the usual pattern. The third person masculine singular, second person singular, and first person plural present forms are shown for an example verb in each class.
- du'- 'die': du'a 'he dies', duuta 'you (sg.) die', duuna 'we die'
- beela'-, 'be hungry': beela'a 'he is hungry', beelofta 'you (sg.) are hungry', beelofna 'we are hungry'
- dhaga'- 'hear': dhaga'a 'he hears', dhageessa 'you (sg.) hear', dhageenya 'we hear' (note that the suffix consonants change)
The common verbs fedh- 'want' and godh- 'do' deviate from the basic conjugation pattern in that long vowels replace the geminated consonants that would result when suffixes beginning with t or n are added: fedha 'he wants', feeta 'you (sg.) want', feena 'we want', feetu 'you (pl.) want', hin feene 'didn't want', etc.
The verb dhuf- 'come' has the irregular imperatives koottu, koottaa. The verb deem- 'go' has, alongside regular imperative forms, the irregular imperatives beenu, beenaa.
An Oromo verb root can be the basis for three derived voices, passive, causative, and autobenefactive, each formed with addition of a suffix to the root, yielding the stem that the inflectional suffixes are added to. Passive voice
- The Oromo passive corresponds closely to the English passive in function. It is formed by adding -am to the verb root. The resulting stem is conjugated regularly. Examples: beek- 'know', beekam- 'be known', beekamani 'they were known'; jedh- 'say', jedham- 'be said', jedhama 'it is said' Causative voice
- The Oromo causative of a verb V corresponds to English expressions such as 'cause V', 'make V', 'let V'. With intransitive verbs, it has a transitivizing function. It is formed by adding -s, -sis, or -siis to the verb root, except that roots ending in -l add -ch. Verbs whose roots end in ' drop this consonant and may lengthen the preceding vowel before adding -s. Examples: beek- 'know', beeksis- 'cause to know, inform', beeksifne 'we informed'; ka'- 'go up, get up', kaas- 'pick up', kaasi 'pick up (sing.)!'; gal- 'enter', galch- 'put in', galchiti 'she puts in'; bar- 'learn', barsiis- 'teach', nan barsiisa 'I teach'. Autobenefactive voice
- The Oromo autobenefactive (or "middle" or "reflexive-middle") voice of a verb V corresponds roughly to English expressions such as 'V for oneself' or 'V on one's own', thought the precise meaning may be somewhat unpredictable for many verbs. It is formed by adding -adh to the verb root. The conjugation of a middle verb is irregular in the third person singular masculine of the present and past (-dh in the stem changes to -t) and in the singular imperative (the suffix is -u rather than -i). Examples: bit- 'buy', bitadh- 'buy for oneself', bitate 'he bought (something) for himself', bitadhu 'but for yourself (sing.)!'; qab- 'have', qabadh- 'seize, hold (for oneself)', qabanna 'we hold'. Some autobenefactives are derived from nouns rather than verbs, for example, hojjadh- 'work' from the noun hojii 'work'.
The voice suffixes can be combined in various ways. Two causative suffixes are possible: ka'- 'go up', kaas- 'pick up', kaasis- 'cause to pick up'. The causative may be followed by the passive or the autobenefactive; in this case the s of the causative is replaced by f: deebi'- 'return (intransitive)', deebis- 'return (transitive), answer', deebifam- 'be returned, be answered', deebifadh- 'get back for oneself'.
Another derived verbal aspect is the frequentative or "intensive," formed by copying the first consonant and vowel of the verb root and geminating the second occurrence of the initial consonant. The resulting stem indicates the repetition or intensive performance of the action of the verb. Examples: bul- 'spend the night', bubbul- 'spend several nights', cab- 'break', caccab- 'break to pieces, break completely'; dhiib- 'push, apply pressure', dhiddhiib- 'massage'.
The infinitive is formed from a verb stem with the addition of the suffix -uu. Verbs whose stems end in -dh (in particular all autobenefactive verbs) change this to ch before the suffix. Examples: dhug- 'drink', dhuguu 'to drink'; ga'- 'reach', ga'uu 'to reach'; jedh- 'say', jechu 'to say'. The verb fedh- is exceptional; its infinitive is fedhuu rather than the expected fechuu. The infinitive behaves like a noun; that is, it can take any of the case suffixes. Examples: ga'uu 'to reach', ga'uuf 'in order to reach' (dative case); dhug- 'drink', dhugam- 'be drunk', dhugamuu to be drunk', dhugamuudhaan 'by being drunk' (instrumental case).
