'archangelic' originates from Greek, specifically the word 'archangelos', where 'arch-' meant 'chief' and 'angelos' meant 'messenger'; the adjective is formed by adding the suffix '-ic'.

'archangelic' changed from Medieval Latin 'archangelicus' (and Old French 'archangélique') and eventually became the modern English word 'archangelic' through Late Latin and Middle English usage.

Initially, it meant 'of or relating to an archangel', but over time it also came to be used figuratively to mean 'supremely angelic or exalted'.
