'uncharacteristically-structured' originates from the prefix 'un-' meaning 'not,' combined with 'characteristically,' which derives from 'characteristic,' and 'structured,' from the Latin 'structura,' meaning 'a fitting together, building.'

'characteristic' evolved from the Greek word 'kharaktēr,' meaning 'a stamping tool,' and 'structured' from the Latin 'structura.'

Initially, 'characteristic' meant 'a distinctive mark,' and 'structured' meant 'to build or arrange.' Over time, 'uncharacteristically-structured' evolved to describe something not typically arranged or built.
