'quickly-chopped' originates from Modern English, specifically the adverb 'quickly' (from 'quick' + '-ly') and the past participle 'chopped' (from the verb 'chop').

'quickly' developed from Old English 'cwic' (meaning 'alive, living') which later took on the sense 'rapid'; the adverb was formed by adding the suffix '-ly'. 'Chop' comes via Middle English 'choppen' (probably imitative/echoic in origin) and produced the past participle 'chopped'. These elements combined in Modern English as a compound modifier.

Initially the parts had different senses ('quick' related to life, 'chop' as an imitative verb), but over time 'quickly' came to mean 'rapidly' and 'chopped' 'cut into pieces'; together they now mean 'cut rapidly' or 'having been cut rapidly'.
