Origin & History of “concrete”
In origin, something concrete is something that has ‘grown together’. The word comes, via Old French concret, from Latin concrētus, the past participle of concrēscere ‘grow together’, hence ‘harden’. this was a compound verb formed from the prefix com- ‘together’ and crēscere ‘grow’ (source also of English crescent, increase, and accrue). Its original application in English was fairly general – referring to that which is solid or material; its use for the building material did not emerge until the early 19th century.
