  Definition:   You learned earlier in this module that the   tense   of a verb indicates   when   an action occurred, but each verb also has a   mood   that tells us   how   the action is viewed or perceived by the speaker. It indicates whether something is a fact, opinion, command, suggestion, request, wish, hypothetical (imaginary) situation, or uncertainty. Moods are as important in writing as they are in our lives because they provide perspective. In English the three primary moods are indicative, imperative, and subjunctive. Indicative Mood Indicative mood  is fact mood, and it's the one we use most often. It states, asks, or denies a fact. However, it can also express an opinion because opinions are often stated as facts; when you have an opinion about something, you usually view it as a fact. Almost all the verbs you've studied so far have been in the indicative mood, so you're already familiar with it. The simple, progressi...
