The word 'richly-produced' is a compound formed from 'richly' (meaning 'in a rich manner') and 'produced' (the past participle of 'produce'). 'Richly' comes from 'rich' + '-ly', and 'produced' comes from the verb 'produce', which originates from Latin 'producere'.

'Richly' and 'produced' were combined in modern English to describe works (like films or music) that are made with great care or expense. 'Produce' comes from Latin 'producere', which became 'produce' in Middle English.

Initially, 'richly' meant 'in a rich manner' and 'produced' meant 'made'. Together, 'richly-produced' evolved to mean 'created with great detail or expense'.
