I’ve heard the term Easter originates from Eostre which is a pagan goddess of the spring. That being said the reference is exclusively an English/Germanic thing. The Orthodox church uses the more ancient term of “Pascha” which derives from “Passover”. So you are partially right but no Christian versed in their history would say it takes away from the holiness of the holiday. The Orthodox church would often observe pagan customs and peacefully orient them towards Christ. As a result the church has a rich tapestry of jurisdictions with their own liturgical nuances. Easter is about Christ defeating death. Glory to God.
