'roughener' originates from the verb 'roughen', which comes from the adjective 'rough', derived from Middle English 'rough', from Old English 'rūh', meaning 'coarse' or 'uneven'.

'roughen' changed from the Old English word 'rūhian' and eventually became the modern English word 'roughen'.

Initially, it meant 'to make rough or coarse', and this meaning has largely remained the same in modern usage.
