The Oromo language is a Cushitic language spoken primarily in Ethiopia and Kenya, especially in the Oromia region of Ethiopia. It is also known as Afaan Oromo or Oromiffa. It is the fourth most-spoken language in Africa, and it is one of the official languages of Ethiopia. There are four variations of the language: Western Oromo, Shewa, Eastern Oromo, and Southern Oromo, which are important to consider with Oromo speech and language development.
Previously, the language was banned and suppressed in Ethiopia, but it has maintained a large base of native speakers and has been reinstated in schools. In the United States, it is also gaining recognition as significant populations exist in Washington D.C., New York, Washington State, and Minnesota. Additionally, Stanford University started offering Oromo classes in 2022.

Interesting Facts About Oromo Speech and Language Development
- Like most other Ethiopian languages, Oromo has a set of ejective consonants, or voiceless stops or affricates that are accompanied by glottalization and an explosive burst of air.
- More than 35% of Ethiopia’s population are Oromo mother-tongue speakers.
- “Oromummaa” is an ideology that fosters Oromo culture and nationalism, including embracing Oromo identity at the personal, community, and national levels.
Language Connections: Somali, Maay-Maay, Oromo, and Amharic
These four languages are spoken in the Horn of Africa and belong to the broader Afro-Asiatic language family, but they come from different branches and have unique linguistic characteristics, so they are addressed in separate essays. However, speech language pathologists may encounter them together in diverse communities, so here is a quick overview of their similarities and differences:
Geographic and Linguistic Relationships
| Language | Language Family | Branch | Primary Country/Region | Script | Mutual Intelligibility |
| Somali | Afro-Asiatic | Cushitic | Somalia, Kenya, Ethiopia | Latin | High with Standard Somali |
| Maay-Maay | Afro-Asiatic | Cushitic | Southern Somalia | Latin | Low with Somali |
| Oromo | Afro-Asiatic | Cushitic | Ethiopia, Kenya | Latin | Not mutually intelligible |
| Amharic | Afro-Asiatic | Semitic | Ethiopia (official) | Ge’ez (Fidel) | No mutual intelligibility |
Clinical Note for SLPs
- Maay-Maay is often grouped with Somali, but the two differ significantly in grammar, phonology, and their level of mutual intelligibility (the ability of speakers of one language to understand speakers of the other language). Treat them as distinct languages during assessments.
- Oromo shares its Cushitic roots with Somali and Maay-Maay, but its syntax and morphology are quite different.
- Amharic, though also Afro-Asiatic, is Semitic and closer in structure to Arabic or Hebrew than to the other three.
- Script differences (Latin vs. Ge’ez) may affect literacy development and should be considered in assessments.
Each language on this site has its own phonological, grammatical, and developmental features described in detail below.

Oromo Consonants in Comparison to English
| Oromo Consonants Not Shared with English | /tʼ/, /kʼ/, /dʼ/, /q/, /ts/, /ɗ/ |
| Consonants Shared With English | /p/, /b/, /t/, /d/, /k/, /g/, /f/, /s/, /m/, /n/, /ŋ/, /l/, /w/, /j/, /h/ |
| English Consonants Not Shared with Oromo | /v/, /z/, /ʃ/, /ʒ/, /tʃ/, /dʒ/, /ð/, /θ/, /ɹ/ |
Oromo Vowels in Comparison to English
| Oromo Vowels Not Shared with English | Long vowel contrasts: /iː/, /eː/, /aː/, /oː/, /uː/ |
| Vowels Shared With English | /i/, /e/, /a/, /o/, /u/ |
| English Vowels Not Shared with Oromo | /ɚ/, /ɔ/, /ʊ/, /ɛ/, /ʌ/, /ə/, /I/, /æ/ |
Notes on Oromo Phonology
- Consonants: Oromo has ejective consonants (/tʼ/, /kʼ/, /dʼ/) and implosive /ɗ/, absent in English. English has fricatives /v/, /z/, /ʃ/, /ʒ/, /θ/, /ð/ and affricates /tʃ/, /dʒ/ absent in Oromo.
- Vowels: Oromo vowels are /i e a o u/ with phonemic length contrasts; English has a more complex vowel system including schwa, lax/tense distinctions, and rhotic vowels.
The Use of Phonotactic Constraints in Oromo Speakers
- Syllable Structure: Oromo primarily allows CV, CVC, and V syllable structures. Consonant clusters are generally not permitted in syllable onsets or codas.
- Consonant Clusters: Oromo does not allow complex consonant clusters in word-initial, medial, or final positions. English clusters (e.g., /st/, /sp/, /bl/, /tr/) may be reduced by Oromo speakers during English acquisition.
- Word-Initial Position: Words may begin with a single consonant or a vowel but never with a consonant cluster.
- Word-Final Position: Single consonants are permitted in final position; however, clusters are avoided, and speakers may add a final vowel (epenthesis) or delete one consonant to simplify clusters.
- Epenthesis: To accommodate English consonant clusters, Oromo speakers may insert a schwa or an echo vowel (e.g., “school” → [səkul]).
- Vowel Length: Oromo has phonemic vowel length, meaning vowel length changes meaning. When acquiring English, speakers may overextend vowel duration where it is not phonemic in English.
- Ejective/Implosive Sounds: Oromo includes ejective (/tʼ/, /kʼ/, /dʼ/) and implosive (/ɗ/) sounds absent in English. Oromo speakers may substitute English stops for these sounds or may apply glottalization in English stops.
- No Final Voiced Stops in Some Dialects: In some Oromo dialects, voiced stops do not occur word-finally. Oromo speakers may devoice final voiced stops when producing English words (e.g., “dog” → [dɔk]).
Language Specific Differences Between English and Oromo
Oromo and English differ in sentence word order, with Oromo using Subject-Object-Verb (SOV) vs. Subject-Verb-Object (SVO) in English. Oromo adjectives typically precede nouns, and it does not use definite or indefinite articles like “a,” “an,” or “the.” Verb tense is marked with suffixes, and Oromo uses a rich system of verb inflection with subject markers, which differs from English auxiliary structures. Oromo does not mark grammatical gender and has consistent plural formation, which may influence the learning of irregular plural and gendered pronoun distinctions in English.
