Enmity is deep, lasting hostility between people or groups who view each other as enemies. It's more than a simple disagreement or momentary anger: enmity describes a serious, ongoing state of hatred or opposition that can persist for years.

In stories, enmity drives conflicts between characters who can't seem to find peace. The Montagues and Capulets in Shakespeare's Romeo and Juliet are locked in enmity, a feud so bitter that it poisons their entire city. In history, enmity between nations has sparked wars, while enmity between political rivals has shaped governments.

Enmity differs from ordinary conflict. Two students might argue over a game and be friends again by lunch, but enmity suggests something harder to heal. It's the cold, settled feeling that people have decided they're permanent opponents. Someone might speak of “ancient enmities” between tribes or kingdoms, meaning hatreds passed down through generations.

When enmity exists between people, trust becomes nearly impossible. They view each other with suspicion and hostility, seeing threats where others might see opportunities for understanding.
