dunce

n. [ From Joannes Duns Scotus, a schoolman called the Subtle Doctor, who died in 1308. Originally in the phrase “a Duns man”. See Note below. ] One backward in book learning; a child or other person dull or weak in intellect; a dullard; a dolt. [ 1913 Webster ]

I never knew this town without dunces of figure. Swift. [ 1913 Webster ]

☞ The schoolmen were often called, after their great leader Duns Scotus, Dunsmen or Duncemen. In the revival of learning they were violently opposed to classical studies; hence, the name of Dunce was applied with scorn and contempt to an opposer of learning, or to one slow at learning, a dullard. [ 1913 Webster ]
