1. (of a person's hair, clothes, or appearance) untidy; disordered:"a man with long dishevelled hair"
Word Originlate Middle English: from obsolete dishevely, from Old French deschevele, past participle of descheveler (based on chevel ‘hair’, from Latin capillus). The original sense was ‘having the hair uncovered’; later, referring to the hair itself, ‘hanging loose’, hence ‘disordered, untidy’. Compare with unkempt.
