A more thorough explanation:

Definition: Hostility is a feeling of strong dislike or anger towards someone or something. It can also refer to a state of conflict or war between individuals or nations.

Examples:

• When two people are arguing and shouting at each other, they are displaying hostility towards each other.
• During a war, there are often acts of hostility such as bombings and shootings.
• When a person is constantly making negative comments and being aggressive towards someone, they are showing hostility towards that person.

The examples illustrate how hostility can manifest in different ways, such as through verbal arguments, physical violence, or negative behavior towards someone. Hostility can also lead to more serious conflicts, such as wars between nations.
