Etymology: "Oof" is imitative: the sound of breath forced out of the body by a blow or a heavy fall. Its closest relatives are the Dutch "oef", a sigh of effort or relief, and the German "uff", which expresses a similar gasp or exhalation. The sound is one people make almost instinctively, which is why so many languages have a version of it. The English interjection has a more surprising shape than its sound suggests. It is a clipping of "ooftish", a word built on "oof", a term for money. Taken from that slang, "oof" once meant cash itself, and "ooftish" was a more playful form of the same idea, so the modern exclamation is the shortened remnant of a word for having funds. Its meaning drifted from the gasp of the body to the wince at a bad situation, leaving the money sense behind.
