If the integral of a derivative of a function produces the original function (within a constant), why are integrals referred to as anti derivatives rather than inverse derivatives?

Inverse functions are unique, whereas antiderivates are actually infinite (one for every choice of the integration constant.)

Well, "anti-" means the same as "inverse" (i.e., opposite to), so I guess it is just a matter of choice and tradition. For me, at least, the word "antiderivative" sounds better, but maybe it's just what I'm used to.
