The word argument is used in several differing contexts in mathematics. The most common usage refers to the argument of a function, but is also commonly used to refer to the complex argument or elliptic argument.

An argument of a function f(x_1,...,x_n) is one of the n parameters on which the function's value depends. For example, the sine sinx is a one-argument function, the binomial coefficient (n; m) is a two-argument function, and the hypergeometric function _2F_1(a,b;c;z) is a four-argument function.
