The vast majority of verbs in sentences are in the indicative mood.
The main verb in a declarative sentence (a statement) or an interrogative sentence (a question) will be in the indicative mood.
Mood is the form a verb takes to show how it is to be regarded (e.g., as a fact, a command, a wish, an uncertainty).
Most sentences are in the indicative mood. Therefore, it can be considered the "baseline" mood. (The biggest point for learners related to the indicative mood is understanding how to form questions.) In essence, the indicative mood is the baseline against which the other more-abstract moods (i.e., the imperative mood and the subjunctive mood) are compared.
