'uniquely' originates from Latin, specifically the word 'unicus,' where 'uni-' meant 'one' and '-cus' meant 'pertaining to.' 'Structured' comes from Latin 'structura,' meaning 'a fitting together, building.'

'Unicus' transformed into the Old French word 'unique,' and eventually became the modern English word 'unique.' 'Structura' evolved into the Old French 'structure,' leading to the modern English 'structure.'

Initially, 'unique' meant 'one of a kind,' and this meaning has largely remained the same in modern usage. 'Structured' originally referred to the act of building, but now also refers to the arrangement or organization of parts.
