“Fie!” expresses moral outrage or shock, as in “Fie on thee, traitor!” It appears in Shakespearean drama and Puritan verse to signal virtue offended or decorum breached. Its brevity and sharp vowel make it ideal for interjections in dialogue or soliloquy. Though obsolete in speech, “fie” survives in poetry as a stylized marker of ethical censure or emotional recoil, often heightening dramatic tension.

Fie expresses moral disapproval, disgust, or shame, like "shame on you!" It's often directed at impropriety, cowardice, or vice. Shakespeare uses it extensively: "Fie, fie upon her!" (Much Ado About Nothing). The exclamation can be repeated for emphasis: "Fie, fie, fie!" Ladies in literature use fie to express shock at indecency. In comedy, fie can be mock-prudish or genuinely scandalized depending on context. Students should note that fie usually condemns moral failings rather than practical errors. The interjection often appears with "on" or "upon" to specify the target. In poetry, fie's brevity and sharp sound suit moments of sudden censure. Compare "faugh!" (disgust at physical unpleasantness) versus fie's moral register.
