Miller uses both direct and indirect characterization in the play.
Examples of direct exposition can be found in each of the first three acts of the play regarding John Proctor, Elizabeth Proctor, Tituba, Danforth, Rebecca Nurse and Reverend Parris. These characters are given direct description by others in the play and these descriptions help to define the character discussed. Exposition of back-story is also provided in the first act and helps to develop character relationships in a direct manner.
In this mode of characterization one person describes another. In Miller's use of indirect exposition, characters define themselves.
Indirect character exposition can be found throughout the play as characters act. Many examples of this type of exposition can be drawn from interpretations of actions and some can be drawn from dialogue.
