'Anastasia' originates from Greek, specifically the word 'Ἀναστασία' (Anastasia), where 'ἀνάστασις' ('anastasis') meant 'resurrection'.

'Anastasia' entered Late Latin as 'Anastasia' and was used in Byzantine Greek and ecclesiastical contexts before becoming a personal name in various European languages and eventually modern English.

Initially, it meant 'resurrection' in a religious/ceremonial sense; over time it became used primarily as a female personal name while retaining the original sense in liturgical contexts.
