lesson: [13] Etymologically, a lesson is ‘something read’ – as indeed the lesson read in church still is. The word comes via Old French lecon from Latin lectiō ‘reading’, a derivative of the verb legere ‘read’ (from which English gets lectern, lecture, etc). The word’s educational sense arose from the notion of a passage of text that a child had to read and learn. => lectern, lecture, legible
lesson (n.)
early 13c., "a reading aloud from the Bible," also "something to be learned by a student," from Old French le?on, from Latin lectionem (nominative lectio) "a reading," noun of action from past participle stem of legere "to read" (see lecture (n.)). Transferred sense of "an occurrence from which something can be learned" is from 1580s.
