The powers that be

In idiomatic English, "the powers that be" (sometimes initialized as TPTB) is a phrase used to refer to those individuals or groups who collectively hold authority over a particular domain.^[1] Within this phrase, the word be is an archaic variant of are rather than a subjunctive be. The use of are in this phrase ("the powers that are") is less common. "The powers that were" (TPTW) can also be found.
