What is a verb mood?

Verb mood is the grammatical term used to describe the relationship between a verb and reality. In other words, it indicates the attitude or purpose of the speaker or writer towards an action or state described by the verb. There are three main verb moods: indicative, imperative, and subjunctive. The indicative mood is used to assert facts or opinions, the imperative mood is used to make commands or requests, and the subjunctive mood is used to express doubt or uncertainty, or to describe hypothetical or unreal situations.
