There are two main levels of language used in A Streetcar Named Desire. These are the text of the stage directions and the words the actors actually say to one another. The biggest contrast is between Stanley's course, slang language and Blanche's classy, flowery statements. While Blanche's language sounds much more proper, it also sounds very fake and false in comparison with Stanley's speech. This is how Williams wanted it to sound when he wrote the play. By using two styles of writing and language, Williams was able to distinguish the two main characters from one another very easily, which tells the reader a lot about the characters' personalities and beliefs.
