The idiom it is what it is has an uncertain origin. We will examine the meaning of the idiom it is what it is, where it came from, and some examples of its use in sentences.
It is what it is means that a situation cannot be changed or mitigated. One may comment it is what it is when he cannot avoid a situation, change someone’s mind, or avoid a certain outcome. It is what it is implies acceptance; it may mean that one is resigned to his fate, or it may mean he is at peace with whatever happens. The origin of the phrase it is what it is is not clear. William Safire traced the phrase to the 1940s, when it was published in the Nebraska State Journal; however, the idiom may have been in use before that time.
