'angelical' originates from Medieval Latin, specifically the word 'angelicalis,' where 'angelicus' meant 'angelic' and '-alis' was a suffix forming adjectives.

'angelicalis' transformed into the Old French word 'angelical,' and eventually became the modern English word 'angelical' through Middle English.

Initially, it meant 'of or pertaining to angels,' but over time it evolved into its current meaning of 'resembling or characteristic of an angel.'
