Verb Tenses, Mood, and Voice
Tense is the time of action expressed by the verb. The simple tenses indicate a general time of action or state of being: present, past, and future. The perfect tenses indicate completed actions. The progressive tenses indicate continuing actions. The perfect progressive tenses indicate actions that continue up to some point in time.
The mood of a verb indicates whether the writer or speaker regards the action as a fact, as a command, or as a wish, request, or condition contrary to fact.
