Origin & History of “baffle”

The etymology of baffle is appropriately baffling. Two main candidates have been proposed as a source. The first is the medieval Scots verb bawchill or bauchle, meaning ‘discredit publicly’. this fits in with the way baffle was first used: ‘I will baffull your good name, sound with the trumpet your dishonour, and paint your pictor with the heeles vpward, and beate it in despight of yourselfe’, Churchyardes chippes 1570. The other strand is represented by French bafouer ‘hoodwink, deceive’, which perhaps comes from Old French beffer. This corresponds more closely to the present-day meaning of baffle, and it may well be that there are two distinct words here.
