c.1300, from Old French glebe, from Latin gleba, glaeba "clod, lump of earth," from PIE *glebh- "to roll into a ball" (cf. Latin globus "sphere;" Old English clyppan "to embrace;" Lithuanian glebys "armful," globti "to embrace, support"). Earliest English sense is "land forming a clergyman's benefice," on notion of soil of the earth as source of vegetable products.
