c.1400, from cement (n.) or Old French cimenter. Figurative use from c.1600. Related: Cemented; cementing.



c.1300, from Old French ciment "cement, mortar, pitch," from Latin cæmenta "stone chips used for making mortar" (singular caementum), from caedere "to cut down, chop, beat, hew, fell, slay" (see -cide). The sense evolution from "small broken stones" to "powdered stones used in construction" took place before the word reached English.
