'uniquely-assembled' originates from the combination of 'unique' and 'assemble', where 'unique' comes from Latin 'unicus' meaning 'only one' and 'assemble' from Latin 'assemblare' meaning 'to bring together'.

'uniquely-assembled' evolved from the combination of the words 'unique' and 'assemble', which were used separately in Middle English and later combined in modern English to describe something distinctively put together.

Initially, 'unique' meant 'only one of its kind', and 'assemble' meant 'to bring together'. Over time, 'uniquely-assembled' came to mean something distinctively put together.
