Verbs are tense

1. Verbs are tense Locating ideas in time

2. Six verb tenses

3. Four principal parts of the verb

4. Auxiliary or helping verbs Helping verbs combine with main verbs to express tense, mood, voice, or condition. In a simple tense the verb stands alone, as a single word: John chortled. In a compound tense the principal part is supplemented by an auxiliary or helping verb to construct the tense: John has chortled, or John will have chortled.

5. Types of helping verbs • There are three types of helping verbs: primary, modal, and marginal.

6. Verbs, like pronouns, have person and number

7. Perfect tenses have finished. • The three perfect tenses are “have” tenses; they all make use of the verb to have as a helping verb. • The perfect tenses are tenses of things that are finished- either finished in the past, present, or future

9. Have, not of • Sometimes we use contractions like should’ve instead of should have. This has lead to the mistaken idea that we are saying should of, but it is should have. • As a matter of style, we do not use contractions in academic writing.

10. are in progress Progressive forms are in progress. • Each of the six tenses also has a progressive form or aspect, an–ingvariation using the present participle- the -ingform of a verb- indicating action still in progress. The progressive form is made with the present participle and one or more auxiliary verbs.
