'crudely-built' originates from the word 'crude,' which comes from Latin 'crudus,' meaning 'raw' or 'unrefined.'

'crudus' transformed into the Old French word 'crude,' and eventually became the modern English word 'crude.' The term 'crudely-built' combines 'crude' with 'built' to describe something constructed in a rough manner.

Initially, 'crude' meant 'raw' or 'unrefined,' and this meaning has largely remained the same in modern usage when describing construction.
