'baptizable' originates from English formation, specifically from the verb 'baptize' + the suffix '-able', where 'baptize' comes from Greek 'baptizein' meaning 'to dip, immerse' and '-able' meant 'capable of'.

'baptizable' changed from the verb 'baptize' (Middle English 'baptisen' from Old French 'baptiser' and Late Latin 'baptizare', originally from Greek 'baptizein') and eventually became the modern English adjective 'baptizable' by adding the adjectival suffix '-able'.

Initially, related to the literal sense 'to dip or immerse', but over time it evolved into the current meaning 'capable of being baptized; eligible for the rite of baptism'.
