Middle English: from Old French ciment (noun), cimenter (verb), from Latin caementum 'quarry stone', from caedere 'hew'.

  • This is from Old French ciment from Latin caementum ‘quarry stone’. Cement was originally used for the material added to mortar to make something closer to concrete, a term only used for building material from the mid 19th century, but which was used in other senses from Late Middle English. It comes from Latin concrescere ‘grow together’.
