A simile is a literary device that compares two things using 'like' or 'as'. An example of a simile used in Pygmalion is, "He is, in fact, but for his years and size, rather like an impetuous baby." This is used to compare Higgins's behavior to that of a baby. Another example in Pygmalion is when Higgins says to Eliza, "Don't sit there crooning like a bilious pigeon." He is comparing Eliza's crying to an annoying bird.
