Origin & History of “cement”
Latin caementa meant ‘stone chips used for making mortar’; etymologically, the notion behind it was of ‘hewing for a quarry’, for it was originally *caedmenta, a derivative of caedere ‘cut’ (from which English gets concise and decide). In due course the signification of the Latin word passed from ‘small broken stones’ to ‘powdered stone (used for mortar)’, and it was in this sense that it passed via Old French ciment into English.
