The declarative mood is a grammatical term used to describe a sentence that makes a statement or assertion - it simply declares something. Synonyms for the declarative mood include the indicative mood, the affirmative mood, and the assertive mood. The indicative mood is used to indicate a state of fact, while the affirmative mood affirms the truth of a statement. Meanwhile, the assertive mood stresses the forcefulness of a given statement. Declarative sentences can be negative or positive, but they always simply make a statement, as opposed to issuing commands or asking questions. With these synonyms, it's easy to identify the tone and purpose of any declarative sentence.
