'inadequately-produced' is a modern compound formed from the adverb 'inadequately' + the past participle 'produced'. 'inadequately' itself derives from the adjective 'inadequate' (in- 'not' + 'adequate') and the adverbial suffix '-ly'; 'produce' originates from Latin 'producere' meaning 'to lead forth' or 'to bring forth'.

'produce' originates from Latin 'producere' (pro- 'forward' + ducere 'to lead'), passed into Old French as 'produire', and entered Middle English as 'produce'/'producen', eventually becoming the modern English 'produce'. 'inadequate' comes from Latin 'in-' (not) + 'adaequatus' (made equal), later via French/Medieval Latin into English; the adverbial '-ly' was added to form 'inadequately'. The compound adjectival use (adverb + past participle) is a productive modern English formation.

Initially, Latin 'producere' meant 'to lead or bring forth'; over time it came to mean 'to make or manufacture' in English. 'Inadequate' initially conveyed 'not equal' or 'not sufficient', and its modern sense of 'insufficient or not meeting standards' is consistent with current usage; the compound now specifically conveys 'made in a way that is insufficient or below standard.'
