Cases in nouns and adjectives

The proto-Semitic three-case system (nominative, accusative and genitive) with differing vowel endings (-u, -a -i), fully preserved in Qur'anic Arabic (see ʾIʿrab), Akkadian and Ugaritic, has disappeared everywhere in the many colloquial forms of Semitic languages. Modern Standard Arabic maintains such case distinctions, although they are typically lost in free speech due to colloquial influence. An accusative ending -n is preserved in Ethiopian Semitic. In the northwest, the scarcely attested Samalian reflects a case distinction in the plural between nominative -ū and oblique -ī (compare the same distinction in Classical Arabic). Additionally, Semitic nouns and adjectives had a category of state, the indefinite state being expressed by nunation.
