Verb

What are Verbs? The verb is king in English. The shortest sentence contains a verb. You can make a one-word sentence with a verb, for example: "Stop!" You cannot make a one-word sentence with any other type of word. Verbs are sometimes described as "action words". This is partly true. Many verbs give the idea of action, of "doing" something. For example, words like run, fight, do and work all convey action. But some verbs do not give the idea of action; they give the idea of existence, of state, of "being". For example, verbs like be, exist, seem and belong all convey state. A verb always has a subject. (In the sentence "John speaks English", John is the subject and speaks is the verb.) In simple terms, therefore, we can say that verbs are words that tell us what a subject does or is; they describe: action (Ram plays football.) state (Anthony seems kind.) There is something very special about verbs in English. Most other words (adjectives, adverbs, prepositions etc) do not change in form (although nouns can have singular and plural forms). But almost all verbs change in form. For example, the verb to work has five forms: to work, work, works, worked, working Of course, this is still very few forms compared to some languages which may have thirty or more forms for a single verb. In this lesson we look at the ways in which we classify verbs

• Verb Classification We divide verbs into two broad classifications: 1. Helping Verbs Imagine that a stranger walks into your room and says: I can. People must. The Earth will. Do you understand anything? Has this person communicated anything to you? Probably not! That's because these verbs are helping verbs and have no meaning on their own. They are necessary for the grammatical structure of the sentence, but they do not tell us very much alone. We usually use helping verbs with main verbs. They "help" the main verb. (The sentences in the above examples are therefore incomplete. They need at least a main verb to complete them.) There are only about 15 helping verbs. 2. Main Verbs Now imagine that the same stranger walks into your room and says: I teach. People eat. The Earth rotates. Do you understand something? Has this person communicated something to you? Probably yes! Not a lot, but something. That's because these verbs are main verbs and have meaning on their own. They tell us something. Of course, there are thousands of main verbs. Helping Verbs Helping verbs have no meaning on their own. They are necessary for the grammatical structure of a sentence, but they do not tell us very much alone. We usually use helping verbs with main verbs. They "help" the main verb (which has the real meaning). There are only about 15 helping verbs in English, and we divide them into two basic groups: Primary helping verbs (3 verbs) These are the verbs be, do, and have. Note that we can use these three verbs as helping verbs or as main verbs. On this page we talk about them as helping verbs. We use them in the following cases:
• be to make continuous tenses (He is watching TV.) to make the passive (Small fish are eaten by big fish.)
• have to make perfect tenses (I have finished my homework.)
• do to make negatives (I do not like you.) to ask questions (Do you want some coffee?) to show emphasis (I do want you to pass your exam.) to stand for a main verb in some constructions (He speaks faster than she does.) Modal helping verbs (10 verbs) We use modal helping verbs to "modify" the meaning of the main verb in some way. A modal helping verb expresses necessity or possibility, and changes the main verb in that sense. These are the modal verbs:
• can, could
• may, might
• will, would
• shall, should
• must
• ought to Here are examples using modal verbs: I can't speak Chinese. John may arrive late. Would you like a cup of coffee? You should see a doctor. I really must go now.

Main Verb

Main verbs have meaning on their own (unlike helping verbs). There are thousands of main verbs, and we can classify them in several ways:

Transitive and intransitive verbs

A transitive verb takes a direct object: Somebody killed the President. An intransitive verb does not have a direct object: He died. Many verbs, like speak, can be transitive or intransitive. Look at these examples:

transitive:

I saw an elephant. We are watching TV. He speaks English.

intransitive:

He has arrived. John goes to school. She speaks fast.

Linking verbs

A linking verb does not have much meaning in itself. It "links" the subject to what is said about the subject. Usually, a linking verb shows equality (=) or a change to a different state or place (>). Linking verbs are always intransitive (but not all intransitive verbs are linking verbs).

Mary is a teacher. (mary = teacher) Tara is beautiful. (tara = beautiful) That sounds interesting. (that = interesting) The sky became dark. (the sky > dark) The bread has gone bad. (bread > bad)

Dynamic and stative verbs

Some verbs describe action. They are called "dynamic", and can be used with continuous tenses. Other verbs describe state (non-action, a situation). They are called "stative", and cannot normally be used with continuous tenses (though some of them can be used with continuous tenses with a change in meaning).

dynamic verbs (examples):

hit, explode, fight, run, go

stative verbs (examples):

be like, love, prefer, wish impress, please, surprise hear, see, sound belong to, consist of, contain, include, need appear, resemble, seem

Regular and irregular verbs

This is more a question of vocabulary than of grammar. The only real difference between regular and irregular verbs is that they have different endings for their past tense and past participle forms. For regular verbs, the past tense ending and past participle ending is always the same: -ed. For irregular verbs, the past tense ending and the past participle ending is variable, so it is necessary to learn them by heart.

regular verbs: base, past tense, past participle

look, looked, looked work, worked, worked

irregular verbs: base, past tense, past participle

buy, bought, bought cut, cut, cut do, did, done
