'angelize' originates from Medieval Latin, specifically the word 'angelizare,' where 'angelus' meant 'angel' and the suffix '-izare' meant 'to make or become.'

'angelizare' transformed into the Old French word 'angeliser,' and eventually became the modern English word 'angelize' through Middle English.

Initially, it meant 'to make into an angel or to treat as angelic,' and this meaning has largely remained the same in modern usage.
