dunce

“But now in our age it is growne to be a common prouerbe in derision, to call such a person as is senselesse or without learning a Duns, which is as much as a foole.”

Francis Thynne, Holinshed’s Chronicles, 1587

The word dunce hasn’t always meant, well, dunce. Named for Scottish scholastic theologian John Duns Scotus, it first referred to a follower of Duns’s teachings, says the OED. Then it gained the derisive meaning of “a hair-splitting reasoner,” due to later philosophers who ridiculed his work, as well as “a dull pedant” and finally someone dull-witted.

Dunce cap might have first been used by Charles Dickens in his novel, The Old Curiosity Shop: “Displayed on hooks upon the wall in all their terrors, were the cane and ruler; and near them, on a small shelf of its own, the dunce’s cap, made of old newspapers and decorated with glaring wafers of the largest size.”
