Shakespeare describes romeo and juliet as "star-crossed lovers." in at least 150 words, explain what this means and how it relates to the play's major themes.

"Star-crossed lovers" is a phrase describing a pair of lovers whose relationship is often thwarted by outside forces. The usage of that term in Romeo and Juliet is foreshadowing for how later in the story, Romeo and Juliet's relationship was thwarted by their feuding parents in multiple ways- for example, the Capulets wanted Juliet to marry another man and stay away from Romeo.
