A helping verb, also called an auxiliary verb, works with a main verb in the same verb phrase.
For example:

Here, is, have, can, and will support the main verbs reading, finished, swim, and leave.

What Comes After a Helping Verb?
Different helping verbs require different forms of the main verb.
| Helping Pattern | Main Verb Form | Example |
|---|---|---|
| modal + base verb | base form | She can swim. |
| do/does/did + base verb | base form | She did go. |
| have/has/had + V3 | past participle | He has eaten. |
| be + -ing form | present participle | She is running. |
| be + V3 | past participle | It was written yesterday. |
Modal verbs such as can, could, may, might, must, should, will, and would normally take the base form.
Correct:
She can swim.
Incorrect:
She can swims.
Likewise, do, does, and did take the base form when they work as helping verbs.
Correct:
Did she go?
Incorrect:
Did she went?
Forms of have normally take a past participle:
She has written the letter.
He had eaten already.
Forms of be combine with an -ing form in continuous structures:
They are working.
They can also combine with a past participle in passive structures:
The room was cleaned.

Helping Verbs vs Main Verbs
Some words function as helping verbs in one sentence and as main verbs in another.
| Helping Verb Use | Main Verb Use |
|---|---|
| He has finished. | He has a bicycle. |
| She does understand. | She does her homework. |
| They did complete the work. | They did the task. |
In:
He has finished.
has supports finished, so it functions as a helping verb.
In:
He has a bicycle.
has carries the central meaning itself, so it functions as the main verb.
Helping Verbs vs Linking Verbs
Forms of be can function as helping verbs or linking verbs depending on the sentence.
| Helping Verb | Linking Verb |
|---|---|
| She is running. | She is tired. |
| They are working. | They are ready. |
| He was sleeping. | He was quiet. |
In:
She is running.
is supports the main verb running.
In:
She is tired.
is connects the subject she with the description tired.
A helping verb supports another verb, while a linking verb connects the subject to a description or identity.
How to Identify Helping Verbs in Sentences
To identify a helping verb, look for a verb that supports another verb in the same verb phrase.
She is reading.
is helps reading.
They have finished.
have helps finished.
He can swim.
can helps swim.
Longer verb phrases may contain more than one helping verb.
She has been studying.
Helping verbs: has, been
Main verb: studying
However, a word should not be classified as a helping verb simply because it appears on a memorized list.
Compare:
She is happy.
Here, is does not support another verb. Instead, it functions as a linking verb.
A useful question is:
Is this verb working with another verb in the same verb phrase?
If yes, it is functioning as a helping verb.
Common Mistakes in Helping Verb Sentences
Helping-verb errors often happen when the wrong auxiliary or main-verb form is used.
| Incorrect | Correct | Why |
|---|---|---|
| She reading. | She is reading. | Continuous form needs a form of be |
| He have finished. | He has finished. | Singular subject takes has |
| They does not know. | They do not know. | Plural subject takes do |
| She can swims. | She can swim. | Modal takes the base verb |
| He will goes. | He will go. | Will takes the base verb |
| Did she went? | Did she go? | Did takes the base verb |
| He has ate. | He has eaten. | Has takes the past participle |
| She is write. | She is writing. | Continuous form requires -ing |
| They has arrived. | They have arrived. | Plural subject takes have |
| He may comes. | He may come. | May takes the base verb |
Checking both the helping verb and the form of the main verb that follows it prevents most of these errors.
