What does fie mean in Shakespeare?

"Fie" is an exclamation used to express disgust, contempt, or disapproval. It is often used in Shakespeare's plays to convey a sense of moral outrage or to emphasize the negative qualities of a character or situation. For example, in Hamlet, the title character uses "fie" to express his disgust at his mother's hasty marriage to his uncle: "Fie, 'tis an unweeded garden,/ That grows to seed; things rank and gross in nature/ Possess it merely." Here, Hamlet uses "fie" to convey his sense of moral outrage at his mother's actions.
