The word 'mildly-produced' is a compound formed from 'mildly' (adverb form of 'mild') and 'produced' (past participle of 'produce'). 'Mild' comes from Old English 'milde' meaning 'gentle or soft', and 'produce' comes from Latin 'producere' meaning 'to bring forth'.

'Mildly' and 'produced' were combined in modern English to describe something made in a gentle way. 'Produce' evolved from Latin 'producere' through Old French 'produire' and Middle English 'producen'.

Initially, 'mildly' meant 'in a gentle way' and 'produced' meant 'made or created'. The compound 'mildly-produced' specifically refers to something made in a gentle or not intense manner.
