Tenses, aspects, and moods (TAMs)

There is no agreement about which tenses, aspects, or moods (TAMs) Proto-Afroasiatic might have had. Most grammars of AA posit a distinction between perfective and imperfective verbal aspects, which can be found in Cushitic, Berber, Semitic, most Chadic languages, and some Omotic languages. The Egyptian verbal system diverges greatly from that found in the other branches. Additionally, it is common in Afroasiatic languages for the present/imperfective form to be a derived (marked) form of the verb, whereas in most other languages and language families the present tense is the default form of the verb. Another common trait across the family is the use of a suppletive imperative for verbs of motion.
