Answer:
sole
Step-by-step explanation:
The word "sole" used in the text to utter a pun together with the word "single" and to stimulate the creation of a joke about the state Romeo was in, as he was single and suffering from a Platonic love he felt for Rosaline .
This excerpt, shown in the question above, was taken from the play "Romeo and Juliet" written by Shakespeare, who was an author who used many puns in his works, making trivial jokes that promoted a comic relief or hid meanings that would be revealed in the course of history.
