The Cushitic languages are a branch of the Afroasiatic language family. They are spoken primarily in the Horn of Africa, with minorities speaking Cushitic languages to the north in Egypt and the Sudan, and to the south in Kenya and Tanzania. As of 2012, the Cushitic languages with over one million speakers were Oromo, Somali, Beja, Afar, Hadiyya, Kambaata, Saho, and Sidama.
Official status
The Cushitic languages with the greatest number of total speakers are Oromo (37 million), Somali (22 million), Beja (3.2 million), Sidamo (3 million), and Afar (2 million).
Oromo serves as one of the official working languages of Ethiopia and is also the working language of several of the states within the Ethiopian federal system including Oromia, Harari and Dire Dawa regional states and of the Oromia Zone in the Amhara Region.
Somali is one of two official languages of Somalia and three official languages of Somaliland. It also serves as a language of instruction in Djibouti, and as the working language of the Somali Region in Ethiopia.
Beja, Afar, Blin and Saho, the languages of the Cushitic branch of Afroasiatic that are spoken in Eritrea, are languages of instruction in the Eritrean elementary school curriculum. The constitution of Eritrea also recognizes the equality of all natively spoken languages. Additionally, Afar is a language of instruction in Djibouti, as well as the working language of the Afar Region in Ethiopia.
Origin and prehistory
Christopher Ehret argues for a unified Proto-Cushitic language in the Red Sea Hills as far back as the Early Holocene. Based on onomastic evidence, the Medjay and the Blemmyes of northern Nubia are believed to have spoken Cushitic languages related to the modern Beja language. Less certain are hypotheses which propose that Cushitic languages were spoken by the people of the C-Group culture in northern Nubia, or the people of the Kerma culture in southern Nubia.
Typological characteristics
Phonology
Most Cushitic languages have a simple five-vowel system with phonemic length (/a a: e e: i i: o o: u u:/); a notable exception are the Agaw languages, which do not contrast vowel length, but have one or two additional central vowels. The consonant inventory of many Cushitic languages includes glottalic consonants, e.g. in Oromo, which has the ejectives /pʼ tʼ tʃʼ kʼ/ and the implosive /ᶑ/. Less common are pharyngeal consonants /ħ ʕ/, which appear e.g. in Somali or the Saho–Afar languages.
Pitch accent is found in most Cushitic languages, and plays a prominent role in morphology and syntax.
Grammar
Nouns
Nouns are inflected for case and number. All nouns are further grouped into two gender categories, masculine gender and feminine gender. In many languages, gender is overtly marked directly on the noun (e.g. in Awngi, where all female nouns carry the suffix -a).
The case system of many Cushitic languages is characterized by marked nominative alignment, which is typologically quite rare and predominantly found in languages of Africa. In marked nominative languages, the noun appears in unmarked “absolutive” case when cited in isolation, or when used as predicate noun and as object of a transitive verb; on the other hand, it is explicitly marked for nominative case when it functions as subject in a transitive or intransitive sentence.
Possession is usually expressed by genitive case marking of the possessor. South Cushitic—which has no case marking for subject and object—follows the opposite strategy: here, the possessed noun is marked for construct case, e.g. Iraqw afé-r mar’i “doors” (lit. “mouths of houses”), where afee “mouth” is marked for construct case.
Most nouns are by default unmarked for number, but can be explicitly marked for singular (“singulative”) and plural number. E.g. in Bilin, dəmmu “cat(s)” is number-neutral, from which singular dəmmura “a single cat” and plural dəmmut “several cats” can be formed. Plural formation is very diverse, and employs ablaut (i.e. changes of root vowels or consonants), suffixes and reduplication.
Verbs
Verbs are inflected for person/number and tense/aspect. Many languages also have a special form of the verb in negative clauses.
Most languages distinguish seven person/number categories: first, second, third person, singular and plural number, with a masculine/feminine gender distinction in third person singular. The most common conjugation type employs suffixes. Some languages also have a prefix conjugation: in Beja and the Saho–Afar languages, the prefix conjugation is still a productive part of the verb paradigm, whereas in most other languages, e.g. Somali, it is restricted to only a few verbs. It is generally assumed that historically, the suffix conjugation developed from the older prefix conjugation, by combining the verb stem with a suffixed auxiliary verb. The following table gives an example for the suffix and prefix conjugations in affirmative present tense in Somali.
