Abaza is a surname.
In Russian, the surname "Абаза" (Abaza) was first recorded among noble families in 1843. It derives from Turkish abaza, meaning stupid, which was originally adopted as a nickname and then morphed into a surname. However, in a Circassian context, the Abazin people's "self-designation" Abaza is separate from this Russian/Turkish origin. The word is also the name of this people's language and of an Egyptian noble family from the same origin.
