We hear language in all its forms in Pygmalion: everything from slang and "small talk," to heartfelt pleas and big talk about soul and poverty. Depending on the situation, and depending on whom you ask, language can separate or connect people, degrade or elevate, transform or prevent transformation. Language, we learn, doesn't necessarily need to be "true" to be effective; it can deceive just as easily as it can reveal the truth. It is, ultimately, what binds Pygmalion together, and it pays to read carefully; even something as small as a single word can define a person.
Pygmalion represents Shaw's attempt to not just use words and language to create art and raise questions, but to force readers to examine the power and purpose of language itself.
Reading Pygmalion, we come to learn that communication is about more than words, and everything from clothing to accents to physical bearing can affect the way people interact with each other.
