At all costs and at any cost are two versions of the same idiom. We will examine the meaning of the idioms at all costs and at any cost, where they came from, and some examples of their idiomatic usage in sentences.
At all costs and at any cost are two idioms that describe a situation in which the speaker is willing to do anything to attain a goal. No matter how big the effort, no matter what the speaker may sacrifice, no matter the price, the speaker is willing to do whatever it takes to achieve something. The phrases at all costs and at any cost came into use in the mid-1800s. Interestingly, the word cost in these two phrases may be an artifact of a definition of cost that has gone out of style. An early definition of cost was way, or course of action.
