Miller employs quite a few literary devices in this play. Dialect and symbolism both work together with the other devices mentioned in the answer above to make A View from the Bridge memorable and meaningful to the audience.
In this play, all the characters except for the narrator, Alfieri, speak in dialect, which is also known as colloquial language, or language specific to a certain part of the world or group of people. The play takes place in Brooklyn, so everyone except Alfieri speaks in the informal style of working class Brooklynites. Eddie, for example, uses shortened versions of words, like "lemme" and "goin'," and he uses "ain't" when conversing with Catherine and others. In contrast, Alfieri speaks in elevated language, describing Brooklyn as a place that lacks "elegance and glamour," a description that is validated by the speech of characters like Eddie.
Various symbols are also identifiable, and they are objects that appear to represent something else relevant to the audience's understanding of the play. Catherine's new dress and later, her high heels, symbolize her maturing, for example; Eddie is slightly alarmed by how grown-up she looks in her new clothes, which is a highly visible symbol for the audience to observe and experience for themselves. Catherine's womanly clothes and shoes are helpfully obvious signs of her leaving childhood behind.
A number of literary devices are employed by Miller in this play. The first and most obvious literary device of the play is the use of a frame story.
The lawyer, Alfieri, opens the story with a monologue (this is another repeatedly used literary device from the play. In a poetic speech, Alfieri introduces the themes of the play, including the background themes and the foreground themes.
In the background of this play stands a notion of the Old World meeting the new. To some extent, the conflicts and tensions of the play grow out of this meeting of two worlds (we might even say "collision" of two worlds).
Alfieri opens and closes the play with the same poetic refrain, repeating certain phrases and reiterating directly the idea that this play is not only about interpersonal conflict but also about a conflict of ages, so to speak.
These monologues function as a frame story, as Alfieri introduces the protagonist in the opening monologue and makes a final comment in the closing coda.
Alfieri serves as spokesperson for all as he delivers the final monologue, bringing the tragic tale to a close.
Additionally, Alfieri functions as the chorus in this play, hearkening back to Greek tradition.
Arthur Miller modeled A View from the Bridge after Greek tragedy: He made the lawyer, Alfieri, the leader of a dramatic chorus...
Alfieri's repeated narration of events helps to control the way time passes in the play, separating periods of time with his monologues. Functionally, these narrative monologues replace scene breaks that would otherwise be used.
