'roughly-constructed' originates from the combination of 'roughly' and 'constructed', where 'roughly' means 'in a rough manner' and 'constructed' means 'built or assembled'.

'Roughly' comes from the Old English word 'ruh', meaning 'coarse or uneven', and 'constructed' comes from the Latin 'constructus', meaning 'to build'.

Initially, 'roughly' meant 'coarse or uneven', and 'constructed' meant 'to build'. Together, they evolved to describe something built in a crude or hasty manner.
