East Cushitic languages
The East Cushitic languages are a branch of Cushitic within the Afroasiatic phylum. Prominent East Cushitic languages include Afar, Oromo, and Somali. Divided into two main sub-branches, the unity of East Cushitic has been contested: linguist Robert Hetzron suggested combining the Sidama like Highland East Cushitic languages with Agaw languages into a "Highland Cushitic" branch, however, other scholars follow in seeing Highland and Lowland as two branches of East Cushitic.
Classification
Clearly distinct subgroups within East Cushitic are Highland East Cushitic, Oromoid, Omo-Tana, Dullay, and Saho-Afar. A number of tree models of how these relate to each other have been put forward. Highland East Cushitic is commonly seen as a primary branch, also in the "traditional" or "classical" view which groups Yaaku with Dullay and groups the rest as Lowland East Cushitic. With the addition of Dahalo, formerly considered to belong to South Cushitic, this classification is also followed by David Appleyard:East CushiticAn influential alternative classification was put forward by Mauro Tosco. His 2000 proposal groups Yaaku and Dullay with part of Lowland and replaces them with all of South Cushitic as the fourth daughter branch of East Cushitic:East Cushitic

Morphology
Noun
Many East Cushitic languages are characterized by marked nominative alignment. Nouns distinguish a nominative and accusative case, but the nominative is only used to mark the subject. Hence, the nominative is commonly referred to as the subject case in Cushitic linguistics, while the accusative is called the absolute case. Besides marking the direct object, the absolute case is used in many other contexts, as well as when case distinctions are neutralized. It is also used as the citation form of the noun, and as the non-verbal predicate kunin nam-a 'this is a man'Most East Cushitic languages have a gender distinction. Nouns are inherently masculine or feminine or, in some languages, a third gender interpreted by linguists as either neuter or a typologically rare "plural gender". Another cross-linguistically rare feature of East Cushitic gender is that the singular and plural of the same lexeme often differ in gender, as in Somali, where most masculine singulars have a feminine plural, and vice versa.
Verb
As in most other branches of Cushitic, the majority of East Cushitic verbs mark their subject agreement and tense–aspect–mood information with suffixes. A typically East Cushitic feature is the threefold distinction between imperfective, perfective, and jussive forms, marked by a changing vowel. This is most clearly seen in Lowland languages like Oromo, but also recognizable in Highland languages like Sidamo:Syntax
Most East Cushitic languages obligatorily mark focus. Sasse cites the following examples from Gidole:he-tóóyé 'he looked'ínno he-tóóyé 'he looked at us'inno tóóyé 'he looked ''at us'''Lexicon
