no-sweat

the term "no-sweat" is a modern american english colloquialism that emerged in the mid-20th century. it is a compound formed directly from the common words "no" and "sweat," where "sweat" metaphorically represents physical exertion, strain, or anxiety. the logic is transparently literal: a situation that induces "no sweat" is one that is effortless or causes no worry. this reflects a characteristically informal and vivid pattern in english where bodily experiences ("sweat," "pain," "breeze") are used to figuratively describe levels of difficulty.

this is a compound adjective formed from the adverb/negative particle "no" and the noun "sweat". it functions as a fixed idiomatic expression.
