concrete

concrete: [14] 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.
=> accrue, crescent, decrease, increase
