  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, progressive, and perfect  tenses  all express indic

  In this lesson you'll learn that   to be   is used as either a   linking   or   helping   verb. Since   to be   is an irregular verb, let's do a quick review of its forms before diving into the material. To Be : Present and Past Tenses Person and Number Present Past First person singular ( I ) am was First person plural ( we ) are were Second person singular or plural ( you ) are were Third person singular ( he ,  she ,  it ) is was Third person plural ( they ) are were To Be : Present and Past Participles Present Past being been To Be  As a Linking Verb To be  is considered a  linking verb  when it's used to describe traits, characteristics, emotions, and states of being. It connects the main noun (or  subject ) to a describing word, such as an  adjective  or another  noun . Traits and Characteristics Daphne  is  very  kind . Is  links the noun  Daphne  and the  adjective   kind . My grandfather  was  a  doctor . Was  links the noun  grandfather  and the describing noun
