The Etymology of Cancel
Cancel reached Middle English in 1391 from Old French canceler, descended from Late Latin cancellare, to cross out a piece of writing by drawing lines across it in the form of cancelli — the lattice grating that screened off the inner court of a Roman tribunal. The Latin cancelli is itself a diminutive of cancer, lattice (also crab — Roman naturalists thought a crab’s crossed claws resembled lattice-work), and the same word lies behind English chancellor (the official who stood at the lattice), chancery (his court), and chancel (the lattice-screened part of a church). To cancel a document, then, was originally a precise legal act: drawing crossed lines through the parchment to mark it as void — visually like a tiny grating. The metaphor expanded outward to cover any annulment, deletion, or withdrawal. The modern colloquial cancelled, for someone publicly disavowed online, sits at the far end of a long Latin lattice.
