Origin

Late 16th century: probably from Middle Dutch schōle 'troop'. Compare with school2.

  • school from Old English:

    The school that children go to derives from Greek skholē ‘leisure, philosophy, place for lectures’, the source also of scholar (Old English). Many ancient Greeks clearly spent their leisure time in intellectual pursuits rather than physical recreation. This is not the same school that large groups of fish or sea mammals congregate in. Here the word comes from early German and Dutch schōle, ‘a troop, multitude’, and comes from the same root as shoal (Old English) and is related to shallow (Late Middle English).
