Avetisyan
Avetisyan is an Armenian surname. It is a patronymic surname derived from the given name Avetis, which is the Armenian form of the biblical name Habakkuk, a Hebrew prophet. The suffix "-yan" is a common Armenian suffix indicating "son of" or "descendant of". Therefore, Avetisyan literally translates to "son of Avetis" or "descendant of Avetis."
The surname is relatively common in Armenia and among the Armenian diaspora. Variations in spelling may occur due to transliteration differences from Armenian to other languages.
