Usage Discussion of teach
Learn in the sense of “teach” dates from the 13th century and was standard until at least the early 19th <made them drunk with true Hollands—and then learned them the art of making bargains — Washington Irving>. But by Mark Twain's time it was receding to a speech form associated chiefly with the less educated <never done nothing for three months but set in his back yard and learn that frog to jump — Mark Twain>. The present-day status of learn has not risen. This use persists in speech, but in writing it appears mainly in the representation of such speech or its deliberate imitation for effect.
