英语词汇shot in the arm的起源、历史背景-英语词源词典

shot in the arm. Anything that gives a person renewed vitali- ty, enthusiasm, determination, confidence, or hope. However, if the expression’s origins were taken into account it would mean short-lived vitality and false hope, for the words derive not from a shot administered by a doctor but from hypodermic injections of narcotics by drug addicts. Some anonymous drug user coined a shot in the arm back in the 1920s, basing it on the medical shot, for medicine injected into the body, which had been invented shortly before it. The phrase has nothing what- soever to do with “Quick, Watson, the needle!,” a saying often attributed to Sherlock Holmes. See also sherlock holmes.
