Explanation: In "Romeo and Juliet" by William Shakespeare, Rosaline is a foil to Juliet. A foil character is one whose main characteristics are opposite to another character. In that way, it highlights the qualities of the other character. Although Rosaline never appears in the play, we are told by other characters that she is quiet, she has sworn not to marry and she eludes the pleasures of the flesh. This highlights Juliet's characteristics. She loves Romeo and says so, and enjoys his company.
