Does language itself have transformative power, or does its power come entirely through the people who use it?

In this play and in British society at large, language is closely tied with class. From a person's accent, one can determine where the person comes from and usually what the person's socioeconomic background is. Because accents are not very malleable, poor people are marked as poor for life. Higgins's teachings are somewhat radical in that they disrupt this social marker, allowing for greater social mobility. In the end language is a tool that can deceive as well as communicate truth. The reader must decide what defines Eliza throughout the book.
