|Charisius, Flavius Sosipater|
The 4th-century Latin grammarian who wrote the Ars Grammatica of Charisius.
1. The work, a compilation, is valuable because it contains excepts from the writings of other grammarians, such as Remmius Palaemon, Cominianus, and Julius Romanus.
2. His claim to fame is that he coined the Latin term adverbium (that which is added to a verb) — from which our term adverb derives — by translating the Greek word epirrhema, adverb.
