What are the figures of speech used in act 3, scene 1?Mainly focusing Macbeth's solliloquy...
Since the focus of figurative speech will be on Macbeth's soliloquy of Act III, scene i, that will narrow it down immensely.
The first figure of speech used by Macbeth is irony, for he fears Banquo, a countryman who fought alongside Macbeth in war and a man who is extremely trustworthy. The irony is found when Macbeth says "Our fears in Banquo / Stick deep."
Another noteworthy bit of figurative speech is the personification Macbeth uses in describing Banquo's "valor" which he says will "act in safety."
Macbeth also uses an allusion to Mark Antony and Caesar as a reference to Banquo and himself .
Macbeth uses a siimile when he compares the witches as "prophetlike."
Then he uses metaphors when he describes his lineage as a "fruitless crown" and a "barren scepter." He continues to use a metaphor when he compares his soul as a "vessel of my peace" and "mine eternal jewel."
Then he personifies "fate" by challenging it.
