'roughly-shaped' originates from the combination of 'roughly' and 'shaped', where 'roughly' comes from 'rough', meaning 'not smooth', and 'shaped' from 'shape', meaning 'form or outline'.

'roughly-shaped' evolved from the Old English word 'rūh', meaning 'rough', and 'sceapian', meaning 'to create or form'.

Initially, it meant 'formed in a rough manner', and this meaning has largely remained the same in modern usage.
