- "Each main verb has five forms. Three of them can be used as a complete main verb:
the -s form (present tense): she writesThe other two forms do not, by themselves, indicate tense:
the past tense form: he wrote
the simple form (present tense): they write
the -ing form: writingThey cannot be used alone as the main verb of a clause."
the participle form (-ed/-en form): written

- Main Verbs in Verb Phrases
"A verb phrase is the helping verb plus the main verb. The final word in a verb phrase, the main verb, carries the primary meaning of the verb phrase. Sometimes more than one helping verb accompanies the main verb. In the following sentences, the verb phrases are bold; HV appears [after] each helping verb, and MV appears [after] each main verb.
He is[HV] biking[MV] to Vermont from Boston.Notice that sometimes words not part of the verb phrase come between the helping verb and the main verb.
They will[HV] arrive[MV] in time for the game.
Cy Young has[HV] always been[HV] considered[MV] one of the best pitchers in baseball history.
"Typical helping verbs include: be, being, been, is, am, are, was, were, do, did, does, has, have, had, must, may, can, shall, will, might, could, would, should."
(The New York Times Guide to Essential Knowledge, 2nd ed. St. Martin's Press, 2007)
- Be, Have, and Do as Main Verbs
"Several verbs, such as be, have, and do, have a variety of syntactic and lexical functions: They can be main or auxiliary verbs.
"John is a student, and he does his homework daily [be and do are main lexical verbs], Bob has been working on his term paper [work is the main lexical verb, and has and been are auxiliary].
" . . . Every English sentence needs to have a verb to be grammatical. However, only the main verb is absolutely essential."
(Eli Hinkel, Teaching Academic ESL Writing: Practical Techniques in Vocabulary and Grammar. Lawrence Erlbaum, 2004)
- Relative Time
"We say He assumes she is single and He assumed she was single; the secondary verb follows the main verb into the past tense, a phenomenon sometimes called the normal sequence of tenses. However, we might also say He assumed she is single. The main verb does not necessarily force its tense on the secondary verb. Often a subordinate verb that expresses something that is always true, not just true at the time of the main verb's action, is in the present tense, as in Galileo believed that the earth moves around the sun--but moved would not be wrong, and some would consider it preferable, since a subordinate clause in the present tense is slightly jarring when the main clause is in a past tense."
(Edward D. Johnson, The Handbook of Good English. Washington Square Press, 1991)
