Middle English: from Old French coustume, based on Latin consuetudo, from consuetus, past participle of consuescere 'accustom', from con- (expressing intensive force) + suescere 'become accustomed'.

  • Both custom and costume (early 18th century) come from the same root, Latin consuetudo ‘custom, habit’—costume was originally the decor and clothing appropriate to a painting with a historical theme. A customer (Late Middle English) was a person who habitually bought from a particular tradesman, and customs (Late Middle English) were payments traditionally made to a lord or king.
