breathe (one's) last

Our Living Language The euphemistic expression breathe one's last illustrates the phenomenon of taboo avoidance. Concepts that few people like to talk about, such as death, are often expressed by circumlocutions or other substitutions for the word that directly expresses the concept (in this case, the verb to die). It is interesting to compare how two different styles of language, formal and slang, avoid saying "die." More formal or elevated speech is full of euphemistic expressions such as breathe one's last, pass away, depart, expire, go to one's eternal reward, go the way of all flesh, and go to a better place. Many of these expressions try to cast death in a positive light, often with religious overtones. Die is absent in slang for the same taboo-avoidance reasons; in addition, slang usually involves coming up with novel expressions for old concepts. The result is a raft of irreverent expressions that are much more direct than the elevated ones—but not so direct as to actually say "die." These expressions often concentrate on a particular physical aspect of dying, lending them an unusually vivid quality: croak, bite the dust, go belly up, kick the bucket, cash in one's chips.
