Final answer:
Macbeth's syntax reveals his troubled and preoccupied state of mind after the murder of King Duncan.
Step-by-step explanation:
The syntax used by Macbeth in the dialogue with Lennox and Macduff reveals that he is troubled and preoccupied by his guilt after having recently murdered King Duncan. His terse and short responses indicate his unease and internal struggle. For example, when Macduff asks if the king is stirring, Macbeth simply responds, 'Not yet', suggesting his guilt and anxiety are affecting his ability to engage in normal conversation.
