'quickly-released' originates from modern English, formed by combining the adverb 'quickly' (itself from 'quick' + the adverbial suffix '-ly') and the past participle 'released' (from the verb 'release').

'quick' comes from Old English 'cwic' meaning 'alive, lively', which developed into Middle English 'quik' (fast); the adverbial suffix '-ly' comes from Old English '-lice'. 'Release' came into English via Old French (e.g. 'releser'/'relasser') and ultimately from Latin roots related to 'loosening' (e.g. 'relaxare'), evolving through Middle English forms into modern 'release'. The compound 'quickly-released' is a modern adjectival combination of these elements.

Originally 'quick' often meant 'alive' and later shifted to 'fast'; the suffix '-ly' formed the adverb 'quickly'. 'Release' originally carried the sense 'to loosen or set free' and has retained that core meaning; combined, the compound now denotes something that was set free or made available in a short time.
