History for fool

In Latin the word follis meant “bag” or (in the plural form folles) “bellows.” In the late stage of Latin that developed into French, follis also took on the meaning “person without sense,” whose head seemed, like a bag or bellows, to be full of nothing but air. Follis became Old French fol, which was borrowed into English as fol, later spelled fool.
