'unreliably-produced' originates from the combination of 'unreliable' and 'produced'. 'Unreliable' comes from the prefix 'un-' meaning 'not' and 'reliable', which is derived from 'rely', originating from Latin 'religare', meaning 'to bind fast'. 'Produced' comes from Latin 'producere', where 'pro-' meant 'forward' and 'ducere' meant 'to lead'.

'Unreliable' evolved from the Middle English 'rely', which was influenced by the Old French 'relier'. 'Produced' evolved from the Latin 'producere', through Old French 'produire', and into Middle English 'produce'.

Initially, 'unreliable' meant 'not to be trusted', and 'produced' meant 'brought forth'. Over time, 'unreliably-produced' came to mean 'produced in a manner that cannot be depended upon'.
