英语词汇take a powder的起源、历史背景-英语词源词典

take a powder. Nobody agrees about the origins of this slang phrase but there are some wonderful explanations. To take a powder means to leave quickly, flee, take off, beat it, dust off, take it on the lam. Powder has been used in the sense of “to rush” since the early 17th century, deriving its meaning from the rapid explosiveness of gun-powder (“Cacheus climb’d the Tree: But O how fast . . . he powder’d down agen,” 1632). But the phrase seems to date back only to the 1920s, when it was first take a run-out powder. One possibility is that it was sug- gested by the dust (or powder) of a person fleeing down the road, another that “flee” suggested “flea” and thus “flea pow- der.” The most ingenious theory is that the powder in the ex- pression represents the “moving” powers of a laxative powder.
