Characterization is the means of a writer to describe, reveal or develop a character for a reader. The writer uses many techniques to bring out the characterization of a character through the use of language. A writer’s use of language is by the application of imagery, metaphor, simile, and other kind of figurative language which are also used by the writer in the text to portray the characters’ traits besides using the dramatic devices such as humour, foreshadowing, irony, pun, suspense and slapstick. Thus, the writer uses application in his description of narrational voice, presentation of the character’s action, speech and thoughts to reveal the characterization of the characters. Besides that, often remarks and comments by other characters and how other characters act, react, think about him will also throw light on his personality and character traits. The use of language in Gulp and Gasp Drama by John Townsend in defining characterization in the play is beautifully displayed. John Townsend uses some of the combination of the techniques mentioned above to dramatically bring out the characterization of Rose, Percy, Lord Septic and Crouch.
