Verb

In English, words are grouped into word classes based on the function they perform in a sentence. There are nine main word classes in English; nouns, verbs, adjectives, adverbs, prepositions, pronouns, determiners, conjunctions, and interjections. This explanation is all about verbs.

A verb is a word that expresses an action, event, feeling, or state of being. They are often thought of as 'doing words', for example, 'she eats' or 'the horse runs'. However, not all verbs are necessarily things that are 'done'; they can also be experienced, e.g. 'Homer thought about the doughnut' or 'Jack loved going to the beach'.

What is a Verb?

Verbs normally describe what the noun or the subject in a sentence is doing. To recap - the subject of the verb is normally the person or thing performing an action, while the object of a verb is normally the person or thing which receives the action. In the case of this sentence 'Homer thought about the doughnut', the subject 'Homer' is the person who 'thought' about the object (the doughnut). Therefore, the verb 'thought' shows what action the person is doing.

Typically, a complete sentence should contain a subject, a verb and an object.

Types of verbs

It's easy to think that verbs are only 'doing words', but this isn't true; there are a number of different verb types. These are;

• Main verbs

  • Dynamic verbs

  • Stative verbs

  • Transitive verbs

  • Intransitive verbs

• Auxiliary verbs

  • Primary auxiliaries

  • Modal auxiliaries

• Linking verbs (copula verbs)

• Imperative verbs

We will explain what each type of verb is and give you plenty of examples to help you understand how they are used.

Main verbs

A main verb is a verb that can stand on its own. It's a strong, independent verb that doesn't need anything else. Main verbs usually describe the actions of the sentence's subject.

Main verbs can 'head' the verb phrase as it carries the most important information and meaning.

Examples of main verbs include:

• Run

• Find

• Look

• Want

• Think

• Decide

Main verbs usually come straight after the subject of the sentence. For example, in the sentence 'The man drove the car.', the main verb 'drove' follows the subject 'the man'.

Fig 1. The man drove the car

Auxiliary verbs

There are twelve auxiliary verbs, divided into two categories: primary auxiliary verbs and modal auxiliary verbs.

Primary Auxiliary verbs

The primary auxiliary verbs are very important. These are the verbs that 'help' to show a verb's tense, voice, or mood. These consist of the various forms of 'to have', 'to be', and 'to do'.

For example:

• Forms of have - has, had

• Forms of be - is, am, are, was, were

• Forms of do - does, did

Let's take a look at these in action:

'He is enjoying the game'

As we know, auxiliary verbs 'help' the main verb. In the sentence 'he is enjoying the game', the verb 'is' helps the main verb 'enjoying'. In this case, it gives information about the tense of the action. Because of the use of the auxiliary verb 'is', we know that the boy is currently enjoying the game in the present tense.

'He had enjoyed the game'

In the sentence 'he had enjoyed the game', the auxiliary verb 'had' shows the action (main verb) was done in the past. Therefore, it helps add information to the verb phrase.

Modal Auxiliary Verbs

There are nine modal auxiliaries:

• Could

• Would

• Should

• Might

• Can

• May

• Want

• Must

• Shall

These verbs show modality, such as possibility (I might go to the shop later), ability (I can dance well), permission (you may marry Juliet), or obligation (I should see my grandma). As you can see from these examples, modal auxiliary verbs can never stand alone as a main verb; instead, they always appear alongside the main verb.

Linking (copula) verbs

Imperative verbs

• Clean your room!

• Be careful!

• Come over here, please.

• Learn your verbs!

As you can see from these examples, imperative verbs are often used at the beginning of a sentence. They often sound demanding, like you are being shouted out!

When using imperative verbs, there is often no subject as the subject is implied or assumed. The subject is usually 'you'. For example, '(you) clean your room' or '(you) be careful!'

Verb Inflections

In English, inflectional affixes (letters added to the beginning or the end of a word) may be added to a verb. These are added to the beginning or end of a word and provide us with extra information.

Verb inflections may be used to express:

• Tense - We can add the inflection '-ed' to regular verbs to show they happened in the past, and we can add the inflection '-ing' to show that the action is continuing. E.g. in the sentence 'The monkey played the piano', the inflection '-ed' at the end of the verb 'play' shows that the action was done in the past.

• Person or number - In English, the inflection '-s' is necessary when using the third person: e.g. 'I play' vs. 'she plays'.

Tenses and verbs

Take a look at this table of tenses for the verb 'to study'. Don't worry about the name of the tenses for now; focus on the inflections of the verbs and the 'helping' auxiliary verbs, which are highlighted in bold:

Fig 2. Inflections of verbs

As you can see, a single verb ('to study') may have a number of different forms, made by adding inflections. Key things to note:

• Primary auxiliary verbs (was, am, have, has, had, been, will) give extra information about tense.

• The modal auxiliary 'will' is used to show that the verb is in the future.

• The inflection '-ing' shows that an action is continuous or ongoing.

• The past tense (and perfect tense) are often formed by adding the inflection '-ed'. For example, both the past simple ('I studied') and the past participle ('I had studied') are formed by adding the inflection '-ed'. In these cases, it is the primary auxiliary 'had' that gives information further about tense.

Irregular verbs

Irregular verbs do not take regular inflections, such as the -ed ending. Instead, the word usually has a completely different spelling.

Take the word 'begin', for example. In the past tense, this becomes 'began', or as a past participle (verb 3), it is 'begun'. This is similar to the verb 'to choose', which becomes 'chose' or 'chosen'.

Let's have a look at another example:

Fig 3. Diagram: Irregular verb 'to give'

The diagram above shows the different forms of the verb 'to give' and its inflections. Each form gives information about tense - 'gives' is present tense, and 'giving' is continuous present (the -ing participle, sometimes called the 'present participle'). The two irregular forms are 'gave', which is in the simple past tense, and 'given', which is the past participle. It is also important to note that not all of these can stand alone, e.g. the word 'giving' often requires the help of a primary auxiliary verb such as 'he is giving' or 'he was giving'.

Unfortunately, there are no rules for irregular verbs.

Suffixes

Suffixes may signal what word class a word belongs to. They often change a word from one word class to another, e.g. the adjective 'short' can become the verb 'shorten' by adding the suffix '-en'.

Here are some common suffixes for verbs:

Verb phrases

A verb phrase is a group of words with a main verb and any other auxiliary verbs that 'help' the main verb. For example, 'could eat' is a verb phrase as it contains the main verb ('eat') and an auxiliary ('could'). More complex verb phrases may also contain complements, direct objects, indirect objects, or modifiers in the phrase. The verb phrase 'I am running' consists of the main verb ('running'), the primary auxiliary ('am'), and the subject ('I'). Verb phrases act as the verb in a sentence.

Phrasal verbs

Phrasal verbs, sometimes called multi-word verbs, are a combination of words that act as a verb, e.g. pick up, hand in, came out, and took off. Phrasal verbs must be read together to get their meaning and often will have a different meaning than the individual parts. For example, 'The movie came out in 2005'. The verb 'came' takes on a different meaning here.

Phrasal verbs are made up of two parts; the main verb (e.g. pick) and an adverb particle (e.g. up).
