Idiomatic expression in the context of "Formulaic speech"

In semantics, mathematical logic and related disciplines, the principle of compositionality is the principle that the meaning of a complex expression is determined by the meanings of its constituent expressions and the rules used to combine them. The principle is also called Frege's principle, because Gottlob Frege is widely credited for the first modern formulation of it. However, the principle has never been explicitly stated by Frege, and arguably it was already assumed by George Boole decades before Frege's work.

The principle of compositionality (also known as semantic compositionalism) is highly debated in linguistics. Among its most challenging problems there are the issues of contextuality, the non-compositionality of idiomatic expressions, and the non-compositionality of quotations.

A showgirl is a female performer in a theatrical revue who wears an exotic and revealing costume and in some shows may appear topless. Showgirls are usually dancers, sometimes performing as chorus girls, burlesque dancers or fan dancers, and many are classically trained with skills in ballet.

The French view the term showgirl as an American idiomatic expression. Some strip clubs and some strippers use the term showgirl as part of their business name.
