Introduction to verbs
Verbs are the words in a sentence that indicate an action, a state of being, or possession. Some examples.
action | state of being | possession | ||
I walk to school. | I feel tired. | This belongs to me | ||
She runs fast. | You look great! | He has good ideas. | ||
It rains in Paris. | We believe you. | She and Tom own a car. | ||
They drink tea. | You and he are tall. | They had two dogs. |
In English, verbs have three general forms: the infinitive form, the base form, and the conjugated form. The infinitive form is always preceded by the word to. The base form is the same as the infinitive but without to. The base form is what you look for in the dictionary. The infinitive and base forms are neutral: There is no tense or person inflected in the verb.

to eat | eat | |
to drink | drink | |
to sleep | sleep |
A conjugated form of a verb indicates when an action takes place (present, past, or future). Sometimes the verb indicates who or what is doing the action though usually English requires a subject in order to determine who or what is doing the action. Here are some examples of conjugated verbs:
She is tired. | third person singular of BE – simple present | |
They went home | third person plural of GO – simple past | |
Tom will call you. | modal verb WILL and the verb CALL – future construction |
Except for the verb BE and modal verbs, all English verbs have only two conjugations in the simple present and only one in the simple past. The verb BE has three conjugations in the simple present and two in the simple past. Modal verbs are not conjugated. Click on the links above to learn.
Like many languages, English has regular verbs and irregular verbs. An English regular verb is a verb in which the simple past is formed by the addition of the morpheme –ed to the base form of the verb. (There are a few small irregularities concerning this morpheme. To learn more, click on simple past.) A regular verb also means that the past participle form is the same as the simple past form. Here are examples of regular verbs in the base form, the simple past, and the past participle form.
regular verbs | ||||
base form | simple past | past participle | ||
call | called | called | ||
belong | belonged | belonged | ||
anticipate | anticipated | anticipated |
For irregular verbs, the simple past is formed by a change in spelling. The past participle sometimes maintains the same form as the simple past, but not always. Other times, the simple past and the past participle are the same as the base form.

think | thought | thought | ||
cut | cut | cut |
Some verbs are called transitive verbs. These verbs are followed by nouns or pronouns that serve as direct objects in the sentence. In general, English sentence structure follows this pattern: subject + verb + direct object.
subject | verb | object |
I | own | a car. |
She | loves | Tom. |
They | plant | trees. |
The tree | has | leaves. |
These verbs require a direct object. Without a direct object, the sentences are incomplete.
correct | incorrect | |||
subject | verb | object | ||
I | own | a car. | I own. | |
She | loves | Tom. | She loves. | |
They | plant | trees. | They plant. | |
The tree | has | leaves. | The tree has. |
Verbs that do not require a direct object are called intransitive verbs. Here are some examples:
subject | verb |
Birds | fly. |
Fish | swim. |
Tom | snores. |
They | agree. |
Some verbs in English can be both transitive and intransitive, Here are examples:
intransitive | transitive | ||||
subject | verb | object | subject | verb | |
They | cook | dinner. | They | cook. | |
Alicia | teaches | English. | Alicia | teaches. | |
I | won | a toy. | I | won. |
