'unrefinedly' originates from the prefix 'un-' meaning 'not' and the word 'refined', which comes from the Latin 'refinire', where 're-' meant 'again' and 'finire' meant 'to finish'.

'refinire' transformed into the Old French word 'refiner', and eventually became the modern English word 'refine'. The adverbial form 'unrefinedly' was later derived by adding the suffix '-ly'.

Initially, 'refine' meant 'to purify or make fine', and 'unrefinedly' evolved to mean 'in a manner that is not refined'.
