Helping verbs are used in a verb phrase (that is, with a second verb) to show tense or form a question or a negative.
Helping verbs are always followed by a second verb, and they show the perfect verb tenses, continuous/progressive verb tenses, and passive voice.
To show tense
The sentence pattern will be:
- Subject (noun, pronoun, or noun phrase)
- Helping verb
- Verb
- The rest of the sentence (adj, adv, noun, prepositional phrase, etc.)
To form a question
The sentence structure will be:
- Helping verb
- Subject (noun, pronoun, or noun phrase)
- Verb
- The rest of the sentence (adj, adv, noun, prepositional phrase, etc.)
Categories
There are three categories for helping verbs: “Do/be/have”, one-word modals, and two-word modals.
Do/Be/Have
These help other verbs make questions, negatives, and some verb tenses. Remember: Do, be, and have are helping verbs only when they are used with a second verb.
Do is a helping verb when it is used to indicate questions, negatives, and emphasis.
Be is a helping verb when it is used to form the continuous/progressive tense or to show passive voice.
HAVE is a helping verb when it is used to show the perfect verb tenses, or used to form a question.
These sentences are in question form. Do/Does/Did are used as helping verbs with Have to form these questions.
- Do you have a car?
- Does he have a car?
- Did he have a car before?
Emphasis with Do
To respond to a statement like, “You don’t want to go to the park,” you may want to reply with great emphasis. Situations like that are perfect for using Do/Does/Did to indicate you really mean something.
In these sentences, Do/Does/Did are used with the verb Want.
- I do want to go to the park.
- He does want to go to the park.
- They really did want to go to the park.
Negatives with Do
Do/Does/Did are used as helping verbs and the word Not to form a negative. In these sentences, they again are used with Want.
- I do not want to go to the zoo.
- He does not want to go to the zoo.
- They did not want to go to the zoo.
Continuous tense with Be
These sentences use Am/Was/Will Be (forms of the verb Be) to form the continuous verb tense with the verb Helping.
- I am helping Diane right now.
- I was helping Diane when George paged me.
- I will be helping Diane when George comes home.
Passive voice with Be
These sentences use Is/Was/Will Be with the verb Canceled to show passive voice.
- The picnic is being canceled because of rain.
- The picnic was canceled because of rain.
- The picnic will be canceled because of rain.
Perfect tense with Have
These sentences use Have/Had with the verb Studied to show the perfect tense.
- I have studied French for two years.
- I had studied French for two years before I went to Paris.
- I will have studied French for three years in August.
Questions with Have
Have is used with the verb Seen to make a question.
- Have you seen that new movie yet?
Modals
Modals are a special kind of helping verb, used to show possibility, probability, and necessity. They:
- Do not show tense
- Do not follow subject/verb agreement
- Do not add an “-s” in the third person singular (he, she, it)
- Are not conjugated
Like other helping verbs, modals are always followed by a second verb. But the second verb follows a different conjugation pattern if a modal is present. The second verb can never add “-s,” “-es,” “-ed,” or “-ing.” It also cannot be in the infinitive form (“to …”) or in the gerund form (“…-ing”).
When using modals, the sentence structure will be:
- Subject (noun, pronoun, or noun phrase)
- Modal (should, would, could, may, might, etc.)
- Verb
- The rest of the sentence (adj, adv, noun, prepositional phrase, etc.)
The Modal page of this guide includes more information on modals, including sentence examples.

As the name suggests, helping verbs “help” the main verb of a sentence. We’ll dive into the difference between auxiliary verbs like “be,” “do,” and “have” and modal auxiliaries like “can” and “could.”
Quick Summary on Helping Verbs
- Helping verbs (also known as auxiliary verbs) help the main verb of a sentence by adding grammatical information to it, like tense, voice, or possibility.
- The most common auxiliary verbs are be, do, and have (and their conjugated forms).
- Modal auxiliaries include can, could, may, might, will, would, shall, should, and must.
What Are Helping Verbs?
Helping verbs add information to the main verb, whether it be by indicating time, voice, possibility, necessity, obligation, other vital information, or by helping form a question. Just in case you need a refresher, verbs are words that express action or state of being.
Helping verbs are also known as auxiliary verbs (or auxiliaries). Be, do, and have (and all their forms) are the most common type of auxiliary verbs, but modal auxiliaries (sometimes known as modals or modal verbs) are also a type of auxiliary verb. In other words, all helping verbs are auxiliaries, but not all auxiliaries are modals.
We’ll explain which words fall under these categories, and what information they add to the main verb.
Helping Verbs List

What Are Auxiliary Verbs?
Be, do, and have are the most frequently used auxiliary verbs. In this section, we’ll be focusing on those three (and their forms) before we move on to modal verbs.
Keep in mind that be, do, and have can be the main verb of a sentence. They are only considered helping verbs if followed by another verb.
Auxiliary verbs help establish tenses. They also help create questions, negate statements, or add emphasis.
(To) Be:
Be and its conjugated forms—am, are, is, was, were—help indicate the progressive (or continuous) aspect. In other words, be shows that an action is or was happening continuously.
I am sleeping in my brother’s bed.
They are preparing for the tournament.
Beatrice is explaining what went wrong yesterday.
He was explaining the rules.
We were practicing for two hours by the time the coach finally arrived.
(To) be is also used in the passive voice.
(To) Do:
As an auxiliary verb, do performs quite a few functions.
1. Forms questions in the simple present and past tense
Do you like this shirt?
Did they win the game?
Doesn’t he attend the other school?
2. Forms negations, or used to form the negative imperative (giving a demand using the negative)
She did not enjoy the play.
We do not expect anything in return.
Please do not bother me right now.
3. Adds emphasis
Alex does want to join you, he’s just being grumpy.
(To) Have:
Have as an auxiliary verb indicates perfect verb tenses and helps form questions.
I had finished eating by the time you arrived.
Depending on the type of perfect tense, have is sometimes used in conjunction with the past participle been.
I had been showering when you called me.
What Are Modal Verbs?
Modal verbs (sometimes known as modal auxiliaries) help demonstrate ability, possibility, probability, necessity, permission, and obligation. These types of verbs never change form. Consider the following sentences:
I may go to sleep.
I can go to sleep.
I must go to sleep.
I should go to sleep.
I will go to sleep.
Although similar, the modal verbs change the sentence meaning ever so slightly.
Here are a few more examples with the rest of the modal verbs:
I might skip today’s practice.
Luis said he could help us move.
Terry ought to know better.
I would offer an explanation, but I know you don’t want one.
She shall leave at the crack of dawn.
It’s worth noting that although not as common, dare, need to, and used to can sometimes function as modal verbs.
Helping the Helper Verbs
Yes, we covered a lot. Although complex, helping verbs play important roles and are necessary to complete certain sentences. Learning about helping verbs can help you in other areas of English grammar, like subject-verb agreement, for example.

We’ve made a mistake, forgotten about an important detail, or haven’t managed to get the point across? Let’s help each other to perfect our writing.
Auxiliary (or Helping) verbs are used together with a main verb to show the verb’s tense or to form a negative or question. The most common auxiliary verbs are have, be, and do.
- Does Sam write all his own reports?
- The secretaries haven’t written all the letters yet.
- Terry is writing an e-mail to a client at the moment.
Auxiliary verbs, also known as helping verbs, add functional or grammatical meaning to the clauses in which they appear. They perform their functions in several different ways:
- By expressing tense ( providing a time reference, i.e. past, present, or future)
- Grammatical aspect (expresses how verb relates to the flow of time)
- Modality (quantifies verbs)
- Voice (describes the relationship between the action expressed by the verb and the participants identified by the verb’s subject, object, etc.)
- Adds emphasis to a sentence
Auxiliary verbs almost always appear together with a main verb, and though there are only a few of them, they are among the most frequently occurring verbs in the English language.
How to Identify an Auxiliary Verb
You probably know that every sentence has at least one verb in it. There are two main types of verbs. Action verbs are used to depict activities that are doable, and linking verbs are used to describe conditions. Both action verbs and linking verbs can accompany auxiliary verbs including the three main ones: do, be, and have.
Sometimes actions or conditions occur only one time and then they’re over. It’s at times like these that some of the same verbs that are used as auxiliary verbs are instead used as action or linking verbs. In this example, we see the word “is”. This is one of the most common auxiliary verbs, but because it stands alone here, it is not functioning as an auxiliary verb.
Jerry slammed the car door on his thumb. He is in horrible pain.
“Is” is a linking verb in this sentence. Because it stands alone, it is not an auxiliary verb.
At other times, an action or condition is ongoing, happening predictably, or occurring in relationship to another event or set of events. In these cases, single-word verbs like is are not accurately capable of describing what happened, so phrases that include auxiliary verbs are used instead. These can be made up of anywhere from two to four words.
A main verb, also known as a base verb, indicates the kind of action or condition taking place. An auxiliary or helping verb accompanies the main verb and conveys other nuances that help the reader gain specific insight into the event that is taking place.
Read the following sentences and explanations to gain greater insight into how auxiliary verbs work.
- Jerry caught his thumb in the car door as coffee spilled from his cup onto his favorite shirt.
- Jerry is always spilling things.
- Since Jerry is also accident prone, he should have been drinking coffee from a mug with a lid, which would not have spilled on his favorite shirt.
In sentence one, caught and spilled, single-word verbs, describe quick, one-time actions of both Jerry and his messy coffee. This sentence does not contain an auxiliary verb.
Since Jerry often has unfortunate accidents, is spilling communicates the frequency of his clumsy actions in sentence two. In sentence three, the auxiliary verbs that make up should have been drinking and would have stained express time relationships as well as an evaluation of Jerry’s actions.
Three Common Auxiliary Verbs
There are just three common auxiliary verbs:
- Have
- Do
- Be
In this section, we’ll take a closer look at how these common verbs work, plus you’ll see some examples.
Have
“Have” is a very important verb that can stand alone in all its tenses, including has, have, having, had, and hadn’t or had not. It is usually used to denote ownership, and it can also be used to discuss ability or describe appearance. “Have” is also a very popular substitute for the verbs “eat” and “drink.” For example: “Let’s have dinner.”
When used as an auxiliary verb, have is always teamed up with another verb to create a complete verb phrase, making it easy to differentiate between uses. You can see the difference in the sentences below:
- Jerry has a large coffee stain on his shirt. → Has = action verb
- Jerry has bought a new shirt to replace the one that was ruined earlier. → Has = auxiliary verb; bought is a past participle that competes the verb phrase.
- Jerry should have been more careful! → Have = auxiliary verb; phrase “should have been” expresses time and evaluates Jerry’s actions.
Do
“Do” can be used as an action verb that stands alone in all its tenses, including to do, do, does, done, did and didn’t, doesn’t or did not .
When used as an auxiliary verb, do is always paired up with another verb to create a complete verb phrase. In some cases, it is used to add emphasis: “I did put the garbage out!” Do is often used to form questions and negated clauses. It is also used in elliptical sentences, where the main verb is understood and is omitted as a result. For example: “He plays piano well, doesn’t he?” or “They all had dinner, but I didn’t.”
- Because he spills things so often, Jerry does more laundry than most people. Does = action verb
- Jerry didn’t put his coffee in a cup with a lid. Didn’t = auxiliary verb
- Jerry doesn’t always spill things, but it happens a lot. Doesn’t = auxiliary verb
Be
“Be” or “to be” is an important verb that has a multitude of uses in English. It can be used as an action verb that stands alone in all its tenses including be, to be, been, am, are, is, was, were, wasn’t, was not aren’t, are not, weren’t and were not.
When used as an auxiliary verb, be is always paired with another verb to create a complete verb phrase. It can be singular or plural, present or past. Negative sentences are formed by adding the word “not”.
- Jerry is messy. Is = action verb
- Although he is always complaining about his accidents, Jerry fails to pay attention. is = auxiliary verb
- Jerry is going to be doing extra laundry for the rest of his life. to be = auxiliary verb
Modal Auxiliary Verbs
In addition to the three main auxiliary verbs, have, do, and be, there are additional auxiliary verbs. These are called modal auxiliary verbs, and they never change form. A complete list of modal auxiliary verbs follows:
- Can
- Could
- May
- Might
- Must
- Ought to
- Shall
- Should
- Will
- Would
Auxiliary Verb Examples
Here are some examples of auxiliary verbs and verb phrases. In the examples below, the verb phrase is italicized and the auxiliary verb is in bold.

You may have heard of helping verbs, which are also referred to as modal and auxiliary verbs. In this discussion, we’ll review what a helping verb is and how it works with another verb.
What Is a Helping Verb?
A helping verb is a verb that combines with a main verb to form a verb phrase. Sometimes it is also called a verb marker, because it indicates that a verb is to follow.
In a sentence with one main verb in the simple present tense, it’s typically easy to identify the verb by looking for the action word. For example:
Jim walks quickly.
Walks is the action being performed by Jim, so that’s the main verb. But what if we want to express a different time (tense) of Jim’s activity? We need another verb to provide that information. In our example with Jim, let’s tell the reader more about his action by placing it in the present progressive tense to convey that he’s doing it right now:
Jim is walking quickly.
You see we now have two verbs. The main verb is walking. The word is has been added to “help” further describe the main verb. In this case, the helping verb (is) tells of the tense of the action (present progressive). Together, the helping verb and the main verb add clarity and context. If we say only Jim walks, that action can apply to any place and any time. By saying Jim is walking, we know his action is happening in this moment.
With that in mind, let’s change our helping verb for what we want the main verb to communicate. We’ll use a Type 1 conditional sentence with a possible condition and a probable result:
If he sees an ice cream truck at the end of the street, Jim will walk quickly.
The main verb is still walk, but our helping verb is now will to let the reader know the time of the action is in the future.
Three Common Helping Verbs
Once you understand the principle of helping verbs, finding and using them gets much easier. You can also begin to recognize many of their common forms, which can change depending on whether they are indicating a past, present, or future action. They can be singular or plural as well.
Here are some helping-verb varieties you probably use every day:
To be: is, am, are, was, were, will be
To have: have, has, had, will have
To do: do, does, did, will do
Examples
We were shopping at the mall yesterday.Joan had been unaware of that until you informed her.
Chris will do what is required to make the delivery on time.
Let’s look at a few more examples:
The dog was eating the food in the bowl.
Janine has visited her mother.
If you’re wondering, Robert did rehearse for several weeks before opening night.
Other helping verbs you might see paired with main verbs include would, should, could, shall, may, might, and can.

Helping verbs (auxiliary verbs) do just what their name implies. They help the main verb in the sentence by telling more about the verb’s tense, mood, and voice.
Main Verbs, Helping Verbs, & Verb Phrases
There are many, many verbs that can function as main verbs (walk, run, think, say, sleep, seem etc.), but there are only a handful of verbs that can function as helping verbs.
List of Helping Verbs
be, am, is, are, was,
were, been, being, have, has, had,
could, should, would, may, might,
must, shall, can, will, do, did, does, having
When we put one or more helping/auxiliary verb with a main verb, we get what is called a verb phrase.
(Every sentence needs to have at least one main verb, but not every sentence needs a helping/auxiliary verb.)
Helping Verb(s) |
+ Main Verb |
= Verb Phrase |
could |
eat |
could eat |
could have |
eaten |
could have eaten |
might have been |
listening |
might have been listening |
Before we move on, I need to tell you something important. Are you ready? Good! The verbs on that list above can function as helping verbs. That wording is very important because some of those words can also function as main verbs. Let’s look at an example using the word was.
I was sleeping during the football game. |
Was sleeping is a verb phrase. Was is a helping verb, and sleeping is a main verb. |
I was captain of the football team. |
This sentence does not have a verb phrase. Here, was is the main verb. It’s a linking verb. |
Sometimes, the helping and main verbs are separated by other words. This often happens when we ask questions. With questions, the auxiliary verb tends to come at the beginning of the sentence, and the main verb comes later.
Words like never, not, and the contraction n’t are not part of the verb. They are adverbs.
Sentence |
Verb Phrase |
Have you been sitting in my chair? |
Have been sitting |
Do you know Goldilocks? |
Do know |
No, I don’t know her. |
do know |
Psst! Have you ever heard of modal verbs? Modals are a type of helping verb that show the speaker’s attitude about what they are communicating.
Verb Phrases Act as Verbs
This seems obvious, right? They are made up of verbs, so what else would they be acting as?
The point here is that they are made up of multiple words and all of the words come together to act as one part of speech, a verb.
The cheesecake might be exploding.
Might be exploding is telling us what the cheesecake is doing. It’s acting as a single unit: a verb.
Did you call Owen?
Did call is asking what you did. It’s acting as a single unit: a verb.
Owen has become a great cook.
Has become is telling us Owen’s state of being. It’s acting as a single unit: a verb.
Sentence diagrams can help us see that verb phrases function as verbs. Sentence diagrams are pictures of sentences that show us how parts of a sentence are related. They make the relationships between words, phrases, and clauses visual.
Verb phrases are diagrammed in the verb slot of the sentence diagram. They go on a horizontal line right after the subject. All of the words in the verb phrase go in the same slot because all of the words are coming together to function as the verb!
Remember that verb phrases are made up of at least one helping verb and a main verb.
Let’s look at an example sentence diagram with an actual sentence.
She must have jumped across the stream.
Must and have are helping verbs, and jumped is a main verb. These three verbs together form a verb phrase.
Don’t Get Tricked
The word of never acts as a helping verb, so would of, could of, and should of are incorrect. They are not verb phrases.
The correct versions are would have, could have and should have or would’ve, could’ve, and should’ve.
