'archangelship' originates from English, specifically the compound 'archangel' + the noun-forming suffix '-ship', where 'archangel' comes from Greek 'arkhangelos' meaning 'chief messenger' and the suffix '-ship' comes from Old English '-scipe' meaning 'state, condition, office'.

'archangel' changed from Late Latin 'archangelus', which in turn was borrowed from Greek 'arkhangelos'; the modern English compound 'archangelship' was formed by adding the native English suffix '-ship' to 'archangel' to denote office or condition.

Initially it designated the 'office or status of an archangel' and this meaning has remained consistent in its rare/technical usage.
