Origin: 1300–50; Middle English levain < Anglo-French, Old French levain < Vulgar Latin *levāmen, equivalent to Latin levā(re) to raise + -men deverbal noun suffix (probably not continuous with Latin levāmen means of alleviating, solace)
mid-14c., from O.Fr. levain (12c.), from L. levamen "alleviation, mitigation," but used in V.L. in its literal sense of "a means of lifting, something that raises," from levare "to raise" (see lever). The verb is attested from early 15c.
