'hastily-packaged' originates from English, combining the adverb 'hastily' (formed from the adjective 'hasty' + the adverbial suffix '-ly') and the past participle 'packaged' (from the verb 'package').

'hasty' developed in Middle English from Old French forms related to 'haste'; 'package' entered English via Old French (e.g. 'paquet'/'pacquet') and Middle English forms (e.g. 'pakage'/'package'), with 'packaged' as the past participle of 'package'. The compound adjective is a modern English formation using an adverb + past participle.

Initially 'hasty' meant quick or rushed and 'package' referred to a bundle; over time the compound has come to mean 'packed quickly and therefore often carelessly or inadequately.'
