unkempt: [15] Unkempt means literally ‘uncombed’. It was coined from the prefix un- ‘not’ and the past participle of the now defunct verb kemb ‘comb’. This came from a prehistoric Germanic *kambjan, a derivative of *kambaz ‘comb’ (ancestor of the English noun comb). It began to be replaced by the new verb comb in the 14th century. => comb[unkempt etymology, unkempt origin, 英语词源]
