'unremarked' originates from the prefix 'un-' meaning 'not' and the word 'remark,' which comes from the Old French 'remarquer,' meaning 'to notice or observe.'

'remarquer' transformed into the Middle English word 'remarken,' and eventually became the modern English word 'remark.'

Initially, 'remark' meant 'to notice or observe,' and 'unremarked' evolved to mean 'not noticed or commented upon.'
