Strong dislike, anger, or unfriendliness, often leading to conflict or violence.
From Late Latin “hostilitas,” from Latin “hostilis” (of an enemy), from “hostis” (enemy). It originally referred to acts of war between states.
Hostility is what happens when disagreement moves from ideas to emotional attack. Even a small amount of hostility in a group can change how safe everyone feels, without a single punch thrown.
