 \indextext{function, overloaded|see{overloading}}%
 When two or more different declarations are specified for a single name
 in the same scope, that name is said to be
-\grammarterm{overloaded}.
+\term{overloaded}.
 By extension, two declarations in the same scope that declare the same name
 but with different types are called
 \term{overloaded declarations}.
