hostile

The word "hostile" describes an attitude, action, or environment marked by strong opposition, unfriendliness, or aggression. It goes beyond simple disagreement. When someone or something is hostile, the feeling is tense, unfriendly, and sometimes threatening. Think of two armies in battle: they are hostile toward each other because they are acting as enemies.

Historically, "hostile" comes from the Latin word hostis, meaning "enemy." That root shows its basic idea: it describes people, actions, or conditions that are against someone or not friendly toward them. It is often used in contexts involving conflict, such as war ("hostile forces"), legal situations ("a hostile witness"), or personal relationships ("a hostile exchange").

However, "hostile" is not limited to people. Places and conditions can also be hostile. A desert is a hostile environment for most plants and animals because it is hard to survive there. In business, a company might face a "hostile takeover," where another firm tries to gain control against the wishes of its management.

You can be hostile by acting in an angry or unfriendly way, feel hostile when you are full of anger or opposition, or describe something as hostile when it feels dangerous, harsh, or unwelcoming. It is a strong word, and it usually suggests open tension rather than quiet dislike. If you sense hostility, you should expect resistance, coldness, or even aggression instead of warmth or support.
