Revenge refers to any form of personal retaliatory action against an individual, institution, or group for some alleged or perceived harm or injustice. It commonly describes a win by a previous loser, to take revenge for (a particular harmful action) or on behalf of (its victim); to avenge, and to take one's revenge (on or upon someone), which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to to take vengeance; to revenge itself, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Revenge as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Revenge therefore works well as a quotation category because it can hold direct statements about the subject, figurative uses that borrow its meaning, and broader reflections that stay anchored to the same central idea. Revenge is not limited to a single rigid definition in ordinary language, and that wider range is part of what makes the category useful for grouping related material without losing the term's main sense.
