Respuesta :
Here romeo is using a metaphor by comparing his soul's weight to lead, meaning he is so sad that his own soul is weighing him down.
Answer:
Antithesis
Explanation:
The figure of speech used in this excerpt from Shakespeare's Romeo and Juliet is Antithesis , which means 'the opposite' . This rhetorical device has the purpose of showing contrasting effect when two opposite ideas are used together in the same sentence: "you have dancing shoes" (this allows her to have free movements ); "I have a soul of lead" (Romeo feels he cannot move ).
