Verb mood refers to the form a verb takes to indicate the writer's or speaker's attitude towards what they are saying. There are three main verb moods in English: indicative, imperative, and subjunctive. The indicative mood is used for statements of fact or opinion. The imperative mood is used for commands or requests. The subjunctive mood is used to express hypothetical or contrary-to-fact situations. Each of these moods affects the way in which a verb is conjugated and used in a sentence.
