@section Introduction to Evaluation
The Lisp interpreter, or evaluator, is the program that computes
-the value of an expression that is given to it. When a function
+the value of an expression that is given to it. When a function
written in Lisp is called, the evaluator computes the value of the
function by evaluating the expressions in the function body. Thus,
running any Lisp program really means running the Lisp interpreter.

The built-in function @code{indirect-function} provides an easy way to
perform symbol function indirection explicitly.
-@c Emacs 19 feature
-@defun indirect-function function
-This function returns the meaning of @var{function} as a function. If
-@var{function} is a symbol, then it finds @var{function}'s function
-definition and starts over with that value. If @var{function} is not a
-symbol, then it returns @var{function} itself.
+@defun indirect-function object
+This function returns the meaning of @var{object} as a function. If
+@var{object} is a symbol, then it finds @var{object}'s function
+definition and starts over with that value. If @var{object} is not a
+symbol, then it returns @var{object} itself.
Here is how you could define @code{indirect-function} in Lisp:
