c. 1300, leisir, "free time, time at one's disposal," also (early 14c.) "opportunity to do something, chance, occasion, an opportune time," also "lack of hurry," from Old French leisir, variant of loisir "capacity, ability, freedom (to do something); permission; spare time; free will; idleness, inactivity," noun use of infinitive leisir "be permitted," from Latin licere "to be allowed" (see licence (n.)).
