Learn
Learn (lẽrn) , transitive verb
[Old English lernen, leornen, Anglo-Saxon leornian; akin to Old Saxon linōn, for lirnōn, Old High German lirnēn, lernēn, German lernen, from the root of Anglo-Saxon laran to teach, Old Saxon lērian, Old High German lēran, German lehren, Gothic laisjan, also Goth lais I know, leis acquainted (in comp.); all prob. from a root meaning, to go, go over, and hence, to learn; compare Anglo-Saxon leoran to go. Compare Last a mold of the foot, lore.]
Learn formerly had also the sense of teach, in accordance with the analogy of the French and other languages, and hence we find it with this sense in Shakespeare, Spenser, and other old writers. This usage has now passed away. To learn is to receive instruction, and to teach is to give instruction. He who is taught learns, not he who teaches.
