For their given names, Bulgarians use many traditional Slavic names in addition to Christian European names. Bulgarian vocabulary words are also sometimes used as names. Recently there has been a revival of some historic Bulgar names such as Asen and Ivaylo. (Bulgar was the Turkic language spoken by the Bulgar people before they adopted a Slavic language.)
Bulgarian names are normally written in the Cyrillic alphabet, the usual alphabet of the Bulgarian language. When they are represented in the Latin alphabet (of English and other western European languages) they are transcribed, which can result in multiple spellings for a single name depending on the transcription.
The word name in Bulgarian is име (ime), plural имена (imena).
