puntiglio

Nobody is sure where 'pun' comes from. The word appeared in English around 1660, and its origin has been debated for three centuries. The leading theory traces it to Italian puntiglio, 'a fine point, a quibble,' from Latin punctum, 'a point.' A pun, on this reading, is a fine point of language — a place where two meanings balance on a single sharp tip.

Other theories exist. Some scholars connect pun to the English word 'pound' (to beat, to hammer), as if a pun hammers a word into two shapes. Others suggest it was clipped from pundigrion, an obscure seventeenth-century word for a joke, whose own origin is unknown. The word pun may itself be a kind of joke — a word without a clear ancestor, wandering English with forged papers.

Shakespeare loved puns. He put them in the mouths of dying men (Mercutio: 'Ask for me tomorrow, and you shall find me a grave man'). He put them in the mouths of kings. He averaged over a hundred puns per play. The Elizabethans did not consider puns low comedy — they considered them proof of linguistic dexterity.

Samuel Johnson called the pun the lowest form of humor. Generations of English teachers repeated him. But the pun persists, unkillable, because it exploits the fundamental instability of language: most words have more than one meaning, and the gap between those meanings is where comedy lives. The pun does not create ambiguity. It finds the ambiguity that was already there.
