      英文詞源


      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
      concrete (adj.)
      late 14c., "actual, solid," from Latin concretus "condensed, hardened, thick, hard, stiff, curdled, congealed, clotted," figuratively "thick; dim," literally "grown together;" past participle of concrescere "to grow together," from com- "together" (see com-) + crescere "to grow" (see crescent). A logicians' term until meaning began to expand 1600s. Noun sense of "building material made from cement, etc." is first recorded 1834.
