      英文詞源


      synthetic (adj.)
      1690s, as a term in logic, "deductive," from French synthétique (17c.) and directly from Modern Latin syntheticus, from Greek synthetikos "skilled in putting together, constructive," from synthetos "put together, constructed, compounded," past participle of syntithenai "to put together" (see synthesis). From 1874 in reference to products or materials made artificially by chemical synthesis; hence "artificial" (1930). As a noun, "synthetic material," from 1934. Related: Synthetical (1620s in logic).
