Shakespeare uses the language of the characters to achieve this multifaceted quality. Through the use of language (specifically Iago, Othello, and Desdemona), Shakespeare propels the plot, engages the audience, creates dramatic irony, and reveals the characters’ psyches.
Shakespeare's writings greatly influenced the entire English language. He expanded the scope of English literature by introducing new words and phrases, experimenting with blank verse, and also introducing new poetic and grammatical structures.
