Old English scolere "student," from Medieval Latin scholaris, noun use of Late Latin scholaris "of a school," from Latin schola (see school (n.1)). Greek scholastes meant "one who lives at ease." The Medieval Latin word was widely borrowed, e.g. Old French escoler, French écolier, Old High German scuolari, German Schüler. The modern English word might be a Middle English reborrowing from French. Fowler points out that in British English it typically has been restricted to those who attend a school on a scholarship.
