Avdey
Avdey is an uncommon Russian male first name. The Russian language borrowed the name from Byzantine Christianity in the form of Avdiy, but in the colloquial usage it transformed into "Avdey". "Avdiy" continued to be a form used by the Russian Orthodox Church, having replaced an earlier form Audiy. The name derives either from the Biblical Hebrew obadyā, meaning god's slave, god's servant, or from Greek audēis, meaning sonorous, melodious—from the Biblical prophet Obadiah.
The diminutives of "Avdey" include Ava and Deya, as well as Avdeyka, Avdya, Avda, Avdyukha, Avdyusha, Avdasha, Avdyunya, Avdusya, Avdyusya, and Adya.
The patronymics derived from "Avdey" are "Авде́евич" and its colloquial form "Авде́ич", and "Авде́евна".
Last names Avdonin, Avdokhin, Avdoshin, Avdyunin, and Avdyushin all derive from this first name.
