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
