CHAPTER I. STUDYING OF VERB IN ENGLISH GRAMMAR
1.1 The features and classification of verbs.
Verbs are very important for language development because they allow children to start building early sentences. Every sentence needs a verb. And the choice of verb determines many of the grammatical forms in a sentence. In fact, a recent study showed that 2-year-old children who use more verbs have more advanced grammatical skills six months later
Full definition of verb is word that characteristically is the grammatical center of a predicate and expresses an act, occurrence, or mode of being, that in various languages is inflected for agreement with the subject, for tense, for voice, for mood, or for aspect, and that typically has rather full descriptive meaning and characterizing quality but is sometimes nearly devoid of these especially when used as an auxiliary or linking verb. As the heart of sentences and clauses, verbs show what the subject is doing or feeling, even if they’re just existing. Verbs are also the only type of word that’s absolutely necessary to make a sentence. Not even nouns, which represent things, need to be in every sentence. Because verbs are so important, they have more rules than other types of words. This can make verbs a little confusing in English, but read on for our explanation of everything you need to know: the different types of verbs, the different forms they take, how to conjugate them in every tense, and some expert tips on how to use them when speaking or writing.
