The sentences The engine stopped and The engine might have been stopped remotely both contain verb phrases. The first verb phrase has one word. The second has several verbs working together.
A verb phrase may be short or complex, but it always includes a main verb. Auxiliary and modal verbs may appear before the main verb to add meanings such as time, possibility, completion, continuation, or passive voice.
What Is a Verb Phrase?
A verb phrase is a main verb alone or a main verb together with any auxiliary and modal verbs linked to it.
The main verb carries the central meaning. The other verbs help express grammatical information.
Consider these examples:
- laughed
- is waiting
- may return
- should have arrived
| Verb Phrase | Main Verb | Additional Meaning |
|---|---|---|
| opened | opened | Simple past action |
| is opening | opening | Action in progress |
| has opened | opened | Perfect aspect connecting an earlier action to the present |
| might open | open | Possibility |
| was opened | opened | Passive voice |
A phrase with only a main verb is sometimes called a simple verb phrase.
The audience applauded.
A verb phrase with one or more auxiliary or modal verbs may be called a complex verb phrase.
The audience might have applauded.
The words simple and complex describe the structure of the verb phrase. They do not show whether the sentence itself is easy or difficult.
Verb Phrase Boundaries: Narrow and Broad Definitions
Grammar resources do not always use the term verb phrase in exactly the same way.
The Classroom Definition
The classroom definition includes:
- the main verb
- auxiliary verbs
- modal verbs
It does not normally include:
- the subject
- objects
- complements
- ordinary adverbial modifiers
Consider:
Sofia has opened the parcel carefully.
Under the classroom definition:
- Verb phrase: has opened
- Subject: Sofia
- Direct object: the parcel
- Adverb: carefully
This article uses the classroom definition unless a broader analysis is specifically mentioned.
The Broader Definition
Some grammar systems use verb phrase for the main verb together with its objects, complements, and modifiers.
Under that analysis, the larger verb phrase in the same sentence may be:
has opened the parcel carefully
This broader definition is common in syntactic analysis because it treats the verb and the words connected to it as one larger unit.
Both definitions are used in reliable grammar resources. The important point is to know which framework is being applied.
Verb Phrase vs. Predicate
Under the classroom definition, a verb phrase and a predicate are not the same.
Consider:
Daniel has repaired the damaged gate this morning.
- Verb phrase: has repaired
- Predicate: has repaired the damaged gate this morning
The predicate includes the verb phrase and the other words that say something about the subject.
Under a broader syntactic definition, the larger predicate may also be described as a verb phrase. This article keeps the terms separate for clarity.
Parts of a Verb Phrase
A verb phrase may contain:
- a main verb
- one or more primary auxiliary verbs
- a modal auxiliary verb
The main verb is essential. The auxiliaries and modals are optional.
The Main Verb
The main verb carries the central action, event, or state.
Examples:
- Maya smiled.
- The accident happened yesterday.
- The room seemed empty.
- Oliver owns two bicycles.
- Nora believes the explanation.
A main verb does not always describe a physical action. It may express:
- an event
- a state
- possession
- thought
- appearance
- existence
In an uninterrupted sequence, the main verb usually comes last:
The technicians may have completed the inspection.
The main verb is completed.
Primary Auxiliary Verbs
The three primary auxiliary verbs are:
- be
- have
- do
They help form different grammatical structures.
Be
Forms continuous and passive constructions:
- is working
- was repaired
Have
Forms perfect constructions:
- has finished
- had arrived
Do
Forms questions, negatives, and emphasis in simple present and simple past structures:
- Do you agree?
- She does not remember.
- I did finish the report.
Modal Auxiliary Verbs
Common modal verbs include:
- can
- could
- may
- might
- must
- shall
- should
- will
- would
A modal appears before the other verbs in the sequence.
Grace might have forgotten the appointment.
The modal might adds the meaning of possibility.
Modal verbs may express:
- ability
- permission
- possibility
- prediction
- necessity
- obligation
- willingness
A base-form verb normally follows a modal:
- can swim
- may arrive
- should listen
- will return
Do not add to after a central modal:
Incorrect:
She may to arrive early.
Correct:
She may arrive early.
How Auxiliary Verbs Build Meaning
Auxiliary and modal verbs add layers of meaning to the main verb.
Continuous Aspect
The continuous aspect uses:
be + -ing form
It presents an action or situation as ongoing.
Lucas is preparing dinner.
- Auxiliary: is
- Main verb: preparing
Another example:
The children were playing outside.
The past form were places the ongoing activity in the past.
Perfect Aspect
The perfect aspect uses:
have + past participle
The perfect aspect connects an earlier action or situation with a later reference time.
Amelia has completed the assignment.
- Auxiliary: has
- Main verb: completed
Another example:
The guests had departed before midnight.
The auxiliary had places the completed action before another past time.
Perfect Continuous Aspect
The perfect continuous combines:
have + been + -ing form
It presents an activity as continuing over a period leading to another time.
Noah has been practising for two hours.
- Perfect auxiliary: has
- Continuous auxiliary: been
- Main verb: practising
Passive Voice
The passive voice commonly uses:
be + past participle
The final decision was announced yesterday.
- Passive auxiliary: was
- Main verb: announced
The subject receives the action rather than performing it.
A passive verb phrase may contain several auxiliaries:
The documents might have been misplaced.
- Modal: might
- Perfect auxiliary: have
- Passive auxiliary: been
- Main verb: misplaced
Modality
A modal verb adds meanings such as possibility, necessity, permission, or prediction.
Compare:
- Ella will attend the meeting.
- Ella may attend the meeting.
- Ella must attend the meeting.
The main verb remains attend. The modal changes the meaning.
Order of Auxiliary Verbs
When several auxiliaries occur together, they normally follow this order:
Modal + perfect have + continuous be + passive be + main verb
Not every verb phrase contains every position.
Consider:
The issue might have been overlooked.
- Modal: might
- Perfect auxiliary: have
- Passive auxiliary: been
- Main verb: overlooked
Now compare:
The engineers will have been working for six hours.
- Modal: will
- Perfect auxiliary: have
- Continuous auxiliary: been
- Main verb: working
English may allow even longer auxiliary sequences, but very long forms are uncommon in ordinary writing. The order remains predictable.
When Be, Have, and Do Are Main Verbs or Auxiliaries
The verbs be, have, and do may function as either main verbs or auxiliary verbs. Their role depends on the sentence.
Be as a Main Verb or Auxiliary
Be as the Main Verb
The room is quiet.
The verb is links the subject room with the complement quiet. It is the main verb.
Be as an Auxiliary
The technicians are checking the system.
The verb are helps form the continuous construction. The main verb is checking.
Another auxiliary use:
The system was checked yesterday.
The verb was helps form the passive voice. The main verb is checked.
Have as a Main Verb or Auxiliary
Have as the Main Verb
Ruby has a new laptop.
The verb has expresses possession. It is the main verb.
Have as an Auxiliary
Ruby has completed the update.
The verb has helps form the perfect aspect. The main verb is completed.
A useful clue is that auxiliary have is followed by a past participle.
Do as a Main Verb or Auxiliary
Do as the Main Verb
Ethan did the research.
The verb did expresses the main action.
Do as an Auxiliary
Ethan did finish the research.
The auxiliary did adds emphasis. The main verb is finish.
In questions and negatives:
Did Ethan finish the research?
Ethan did not finish the research.
The form did acts as an auxiliary, while finish remains the main verb.
Verb Phrases in Questions and Negative Sentences
The linked verbs in a verb phrase do not always appear next to each other.
Questions
In many questions, the first auxiliary moves before the subject.
Has Olivia submitted the form?
The linked verbs are:
- Auxiliary: has
- Main verb: submitted
The subject Olivia appears between them.
Another example:
Will the team have completed the work by Friday?
The verb sequence is will have completed, even though the subject separates will from the other verbs.
Negative Sentences
The negative word not usually appears after the first auxiliary.
Olivia has not submitted the form.
The linked verbs are has and submitted. The word not makes the clause negative.
When no auxiliary is already present in a simple present or simple past clause, English usually adds a form of do:
Liam does not understand the instructions.
We did not receive the message.
Adverbs Between Linked Verbs
An adverb may also appear between an auxiliary and the main verb.
Olivia has already submitted the form.
The package may never arrive.
Ethan has carefully checked every figure.
Under the classroom definition used here, the verb phrase consists of the linked verbs. The adverb modifies the verb phrase but is not included in its narrow boundary.
How to Identify a Verb Phrase
Use the following steps when a sentence contains several verbs or verb forms.
1. Find All Verb Forms
Look for words that express actions, events, states, or grammatical support.
In:
The visitors might have been waiting outside.
The verb forms are:
- might
- have
- been
- waiting
2. Identify the Main Verb
Find the verb carrying the central meaning.
The main verb in the example is waiting.
The other verbs add grammatical information.
3. Look for Linked Auxiliaries and Modals
Check the words before the main verb.
might have been waiting
- might: modal
- have: perfect auxiliary
- been: continuous auxiliary
- waiting: main verb
Together, they form the complete verb phrase.
4. Decide Whether Be, Have, or Do Is an Auxiliary
Ask whether the verb is followed by another verb form.
Compare:
Maya has a bicycle.
Has is the main verb.
Maya has repaired the bicycle.
Has is an auxiliary. Repaired is the main verb.
5. Exclude the Subject
Under the classroom definition, the subject does not belong to the verb phrase.
The young mechanic has repaired the engine.
- Subject: the young mechanic
- Verb phrase: has repaired
The subject and verb phrase together help form the clause.
6. Exclude Objects and Ordinary Modifiers
Under the chosen definition:
The young mechanic has repaired the engine carefully.
- Verb phrase: has repaired
- Direct object: the engine
- Adverb: carefully
A broader grammar system may include the object and modifier within a larger verb phrase. The classroom boundary remains has repaired.
7. Check for Split Verb Phrases
Remember that a subject, not, or an adverb may separate linked verbs.
Has the mechanic already repaired the engine?
The linked verb sequence is has repaired.
8. Identify the Meaning Added by the Auxiliaries
Ask what each auxiliary contributes.
might have been repaired
- might: possibility
- have: perfect aspect
- been: passive voice
- repaired: main meaning
This final check confirms that the verbs belong together.
Worked Verb Phrase Analysis
Consider:
The final documents might not have been delivered to the correct office.
The complete clause contains:
- Subject noun phrase: the final documents
- Modal verb: might
- Negative marker: not
- Perfect auxiliary: have
- Passive auxiliary: been
- Main verb: delivered
- Prepositional phrase: to the correct office
Under the classroom definition, the verb phrase is:
might have been delivered
The word not makes the clause negative but is not included in the narrow verb-phrase boundary used here.
The full predicate is:
might not have been delivered to the correct office
Each verb contributes a different layer of meaning:
- might: possibility
- have: completed or earlier relevance
- been: passive voice
- delivered: central action
Verb Phrase vs. Phrasal Verb
A verb phrase and a phrasal verb are different grammatical concepts.
| Verb Phrase | Phrasal Verb |
|---|---|
| Contains a main verb with possible auxiliaries or modals | Contains a verb and one or more particles |
| Expresses tense, aspect, voice, or modality | Often creates a new lexical meaning |
| has been waiting | gave up |
| might return | looked after |
A phrasal verb may appear inside a larger verb phrase:
Maya has turned down the offer.
The complete verb phrase is:
has turned down
Inside it:
- Auxiliary: has
- Phrasal verb: turned down
- Main verb element: turned
- Particle: down
The particle helps create the meaning refused.
The article on phrasal verbs should handle topics such as particles, meanings, and separable structures in detail. The key point here is that verb phrase and phrasal verb do not mean the same thing.
Verb Phrase vs. Verbal Phrase
The terms verb phrase and verbal phrase also describe different structures in traditional grammar.
A verb phrase functions as the verb of a clause:
The workers have repaired the roof.
A verbal phrase is built around a non-finite verb form and performs another grammatical function.
| Structure | Example | Function |
|---|---|---|
| Gerund phrase | Repairing the roof took two days. | Noun |
| Infinitive phrase | The workers planned to repair the roof. | Complement of the verb planned |
| Participial phrase | Damaged by the storm, the roof needed urgent work. | Adjective modifier |
In Repairing the roof took two days, the group repairing the roof functions as the subject.
In The workers have repaired the roof, have repaired functions as the verb phrase of the clause.
Some modern grammar systems may classify certain verbal phrases as non-finite clauses. This article uses the familiar classroom terminology.
FAQs About Verb Phrases
Can a Verb Phrase Be One Word?
Yes. A main verb may form a complete verb phrase by itself, as in The baby slept.
What Is the Main Verb in a Verb Phrase?
The main verb carries the central action, event, or state. It normally appears after any auxiliary or modal verbs.
How Many Helping Verbs Can a Verb Phrase Have?
A verb phrase may contain several auxiliaries, as in might have been delayed. English auxiliaries follow a predictable order before the main verb.
Can an Adverb Appear Between the Verbs in a Verb Phrase?
Yes. An adverb may separate an auxiliary from the main verb, as in has already finished. The verbs remain linked even though they are not next to each other.
What Is the Difference Between a Verb Phrase and a Phrasal Verb?
A verb phrase contains a main verb with any auxiliaries or modals linked to it. A phrasal verb combines a verb with a particle, often creating a distinct meaning.
What Is the Difference Between a Verb Phrase and a Predicate?
Under the classroom definition, a verb phrase contains the main verb and its auxiliaries or modals. The predicate includes the verb phrase and the other words that say something about the subject.
