- concrete (adj.) late 14c., "actual, solid; particular, individual; denoting a substance," from Latin concretus "condensed, hardened, stiff, curdled, congealed, clotted," figuratively "thick; dim," literally "grown together;" past participle of concrescere "to grow together," from assimilated form of com "together" (see con-) + crescere "to grow" (from PIE root *ker- (2) "to grow").
- concrete (n.) 1520s, "that which is material or not abstract," a noun use of concrete (adj.). Meaning "a mass formed by concretion" is from 1650s, from the literal sense of Latin concretus. Hence "building material made from sand, gravel, stone chips, etc., cemented together" (1834).
