The progressive tense (also called the progressive aspect) is sometimes referred to as the imperfect tense.
There are six progressive tenses: present, past, future, present perfect, past perfect, and future perfect. Some grammarians refer to the progressive tense as the progressive aspect of a verb. The progressive tense shows an “ongoingness” of the action denoted by the verb.
The progressive tense is formed by using the verb to be as an auxiliary verb and adding the present participle (-ing) of the verb. You form a particular tense simply by conjugating the verb to be in that tense and adding the present participle of the verb.
