From Ancient Greek πτηνός (ptēnós, “flying, winged creature, bird”), from πέτομαι (pétomai), itself from Proto-Indo-European *péth₂eti (“to fly”) from the root *peth₂- (literally “to spread one’s wings”).
Beware Slavic false cognates such as Bulgarian пти́ца (ptíca), Macedonian птица (ptica), Russian пти́ца (ptíca), Serbo-Croatian пти̏ца/ptȉca, Ukrainian пти́ця (ptýcja), all meaning bird from Proto-Slavic *pъtica. True cognates are Old English feþer (English feather), Latin petō, Russian перо́ (peró), Sanskrit पतति (pátati), Avestan 𐬞𐬀𐬙𐬀𐬌𐬙𐬌 (pataiti), Old Armenian թիռ (tʻiṙ).
