Resembling, relating to, or characteristic of an angel; heavenly or innocent.
From Late Latin 'angelicus' derived from 'angelus' (angel), with the addition of the English adjectival suffix '-al'.
The word 'angelical' is mostly archaic now—modern English prefers 'angelic'—but you can still find it in older literature like Milton's Paradise Lost, showing how some words slowly get dropped in favor of simpler versions.
