Etymology: "Unteaching" is built from the prefix "un-" attached to "teach," and the "un-" here works as a reversal: it means to undo what teaching has put in place. "Teach" itself traces back to Old English "tǣcan," meaning to show or point out, which is why teaching has always carried a sense of presenting something to a learner. Adding "un-" turns that act around, so the word describes deliberately dismantling knowledge or habits that someone has already absorbed. The idea sits comfortably alongside older verbs like "unlearn," which follows the same pattern of reversing an earlier act. Where "unlearn" focuses on forgetting, "unteach" puts the emphasis on removing ideas that were taught, often ones that feel so natural they go unnoticed. The word is most often heard in discussions of education and training, where unlearning a deeply held assumption can be harder than learning something new.
