(fast-release)
released quickly
Etymology
'fast-released' is a modern English compound from 'fast' + 'release'. 'fast' originates from Old English, specifically the word 'fæst', where it meant 'firm, fixed'. 'release' originates from Old French, specifically the word 'releser', ultimately from Latin components 're-' + 'laxare' where 're-' meant 'again' (or intensifier) and 'laxare' meant 'to loosen'.
'release' entered Middle English from Anglo-Norman/Old French 'releser' and evolved into the modern English 'release'. 'fast' has been inherited from Old English 'fæst' into modern English. The compound 'fast-release' and adjectival form 'fast-released' are comparatively recent technical formations (particularly 20th century) used in pharmaceutical and product descriptions.
Originally, 'fast' primarily conveyed 'firm, fixed' in Old English, while 'release' meant 'to loosen or set free' in Latin/Old French. Over time 'fast' also came to be used in senses related to speed in modern usage, and 'release' broadened to include the discharge of substances; together they now mean 'released quickly'.
