What does the title of the play stand for?A Streetcar Named Desire

Literally, the title, A Streetcar Named
Desire, refers to the streetcar Blanche rides into town on.  Of course,
desire plays a much larger role in the play than
that.

Desire is why Stella stays with Stanley.  After he
abuses her she looks forward to the passion they'll share when they make up.  Desire is
what Stanley can fulfill for her that her former plantation life, Blanche, etc.,
cannot.  Desire is connected to violence in the play, and is prevelant.  In addition to
Stanley and Stella, the couple who live above them also have a relationship that
contains violence.

Desire also plays a major role in
Blanche's character.  It's part of the reason for her former life that she tries to hide
from Stanley and Stella, etc., it is revealed when she attempts to seduce the young boy
that enters the house, and is revealed by her flirting with Stanley.  The play reveals a
disparity between how women act in Southern society, and how women are expected to act
in Southern society.  Blanche is figuratively trapped between how she wants to live, and
how she is forced to live. 

Violence, of course, mixed with
desire--Stanley's--also destroys Blanche and leads to her
madness.

The play basically breaks down into a battle for
Stella between Blanche and Stanley.  And Stanley wins, largely because he fulfills
Stella's desire.
