'quickly-inflated' is a compound formed from the adverb 'quickly' and the past-participle form 'inflated'. 'quickly' originates from Old English elements related to 'quick' (Old English 'cwic' meaning 'alive, lively') plus the suffix '-ly'. 'inflate' originates from Latin 'inflāre', where 'in-' meant 'into' and 'flāre' meant 'to blow'.

'quickly' developed from Old English 'cwic' -> Middle English 'quik' -> modern English 'quick' + adverbial suffix '-ly' to form 'quickly'. 'inflate' came from Latin 'inflāre' -> (via Old French/Medieval Latin forms) Middle English 'inflaten' -> modern English 'inflate'. These two elements were later combined in English as a descriptive compound (adverb + past participle) to make phrases like 'quickly-inflated'.

Initially the component words meant 'fast' (quick/quickly) and 'to blow into / to swell' (inflate). Over time, combining them produced the adjectival compound meaning 'having been inflated quickly', which is a straightforward compositional meaning rather than a large semantic shift.
