'baptizee' originates from English, specifically formed from the verb 'baptize' plus the English/French-derived suffix '-ee' (from French '-é') meaning 'one who receives the action'.

'baptizee' is a modern English formation: the verb 'baptize' (from Late Latin 'baptizare' and Greek 'baptizein') combined with the agent/recipient-forming suffix '-ee' (borrowed via French), producing a noun meaning 'one who is baptized.'

The root 'baptize' ultimately comes from Greek 'baptizein' originally meaning 'to dip' or 'to immerse'; over time it came to mean the Christian rite of baptism, and 'baptizee' specifically denotes the person who receives that rite.
