Writing style of Pygmallion

In calling Pygmalion a romance (its subtitle is "A Romance in Five Acts"), Shaw was referencing a well-established literary form (not usually employed in theatre), to which Pygmalion does not fully conform. (Shaw was aiming to provoke thought by designating his play thusly.) The term romance does not imply, as it was misinterpreted to mean by many of Shaw's contemporaries, a romantic element between Liza and Higgins. Since the middle ages, romances have been distinguished from more realistic forms by their exotic, exaggerated narratives, and their idealized characters and themes. Shaw playfully suggests Pygmalion is a romance because of the almost magical transformations which occur in the play and the idealized qualities to which the characters aspire.
