+There are some well-known linguistic applications of Combinatory
+Logic, due to Anna Szabolcsi, Mark Steedman, and Pauline Jacobson.
+Szabolcsi supposed that the meanings of certain expressions could be
+insightfully expressed in the form of combinators. A couple more
+combinators:
+
+ **C** is defined to be: `\f x y. f y x` [swap arguments]
+
+ **W** is defined to be: `\f x . f x x` [duplicate argument]
+
+For instance, Szabolcsi argues that reflexive pronouns are argument
+duplicators.
