'jointly-produced' originates from the combination of 'jointly' and 'produced', where 'jointly' comes from the Latin 'junctus', meaning 'joined', and 'produced' from the Latin 'producere', meaning 'to bring forth'.

'jointly' evolved from the Old French 'joint', and 'produced' from the Old French 'produire', eventually forming the modern English term 'jointly-produced'.

Initially, it meant 'brought forth together', and this meaning has largely remained the same in modern usage.
