The art or process of making a compound by putting the
   ingredients together, as contrasted with analysis; thus, water is made
   by synthesis from hydrogen and oxygen; hence, specifically, the
   building up of complex compounds by special reactions, whereby their
   component radicals are so grouped that the resulting substances are
   identical in every respect with the natural articles when such occur;
   thus, artificial alcohol, urea, indigo blue, alizarin, etc., are made
   by synthesis.
