A function applied to (some of) its arguments. If it is not applied to all its argument then it is a "{partial application}". Application is usually written in the form f(x) but some languages such as command-line interpreters and many functional languages use juxtaposition: f x. Lisp places the parentheses around the whole application: (f x).
