      英文詞源


      dose
      dose: [15] A dose is literally ‘that which is given to one’ – etymologically and semantically, it is a parallel formation to donation. It comes via French dose and late Latin dosis from Greek dósis, a derivative of the verb didónai ‘give’ (which is related to English date, donate, etc). It originally meant simply ‘giving, gift’, but was used by Greek physicians such as Galen for ‘portion of medicine administered’, and it is that application that has proved most durable. The modern slang sense ‘venereal infection’ dates from just before World War I.
      => date, donate
      dose (n.)
      early 15c., "the giving of medicine (in a specified amount or at a stated time)," from Middle French dose (15c.) or directly from Late Latin dosis, from Greek dosis "a portion prescribed," literally "a giving," used by Galen and other Greek physicians to mean an amount of medicine, from stem of didonai "to give" (see date (n.1)). Slang meaning "venereal disease" is from 1914.
      dose (v.)
      1650s, from dose (n.). Related: Dosed; dosing.
