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.
