A verb phrase is a main verb together with one or more auxiliary verbs, or, in a broader grammatical analysis, the complete predicate built around that verb. Verb phrases express actions and states while marking tense, aspect, mood, voice, negation, and emphasis, as in has been studying, might leave, and was repaired yesterday.
Key Facts at a Glance
- A strict verb phrase contains the lexical main verb and any auxiliary verbs attached to it.
- A broad verb phrase can include objects, subject complements, and adverbial modifiers.
- The first verb in a finite verb phrase carries tense and agreement; later verbs use non-finite forms.
- English auxiliary order is generally modal, perfect have, progressive or passive be, then the lexical verb.
- A phrasal verb combines a verb with a particle or preposition, but not every verb phrase is a phrasal verb.
- A substitution test can help identify the complete verb phrase in a sentence.
What Is a Verb Phrase?
A verb phrase is the part of a clause organized around a verb. In The researchers have completed the experiment, the strict verb phrase is have completed. The broader predicate is have completed the experiment, because the noun phrase the experiment receives the action.
Verb phrases may contain one verb or a chain of verbs. Birds migrate has a one-word verb phrase, while The birds may have been migrating contains the modal may, perfect auxiliary have, progressive auxiliary been, and main verb migrating.
The phrase is not defined by length. A two-word combination such as did leave and a five-word combination such as could have been being monitored can both function as verb phrases. Their difference lies in grammatical structure, not word count.
Strict and Broad Definitions
Traditional school grammar usually uses the strict definition: the verb phrase consists of the main verb and its helping verbs. Many linguistic descriptions use a broader definition in which the verb phrase includes the verb group plus its complements and modifiers.
| Sentence | Strict verb phrase | Broad predicate or verb phrase |
|---|---|---|
| Maya laughed loudly | laughed | laughed loudly |
| The team has won the match | has won | has won the match |
| We were waiting at noon | were waiting | were waiting at noon |
| He seems unusually tired | seems | seems unusually tired |
| The window was broken by hail | was broken | was broken by hail |
Neither framework is automatically wrong. A teacher asking students to identify tense may expect was broken. A syntax assignment examining the predicate may expect was broken by hail.
How Does a Verb Phrase Work?
A verb phrase works through a hierarchy in which each auxiliary controls the form of the verb that follows. The lexical verb contributes the central meaning, while auxiliary verbs contribute grammatical information such as time, completion, duration, possibility, obligation, or passive voice.
The usual maximum sequence in standard English is:
modal + perfect have + progressive be + passive be + main verb
For example:
The bridge might have been being inspected.
The chain contains might as the modal, have as the perfect auxiliary, been as the progressive auxiliary, being as the passive auxiliary, and inspected as the lexical verb. Such a sentence is grammatical, but speakers often replace it with the clearer The bridge might have undergone inspection or Inspectors might have been inspecting the bridge.
What Is the Auxiliary Order?
English auxiliary order normally follows this pattern:
- A modal may appear first.
- A form of have marks perfect aspect.
- A form of be marks progressive aspect.
- Another form of be may mark passive voice.
- The main verb appears last in the chain.
| Function | Auxiliary pattern | Required following form | Example |
|---|---|---|---|
| Modal | can, should, might | Base form | should leave |
| Perfect | have, has, had | Past participle | has left |
| Progressive | am, is, are, was, were | Present participle | is leaving |
| Passive | am, is, are, was, were | Past participle | was invited |
| Perfect progressive | have + been | Present participle | have been leaving |
| Perfect passive | have + been | Past participle | have been invited |
The first verb in a finite chain carries tense and, where relevant, subject agreement. In She has been working, has is finite because it changes to have with they and to had for past time. Been and working are non-finite forms.
Why Do Verb Forms Change After Auxiliaries?
Each auxiliary selects a particular form after it. A modal selects the base form, have selects a past participle, and progressive be selects an -ing form.
- They will arrive, not They will arrived.
- He has gone, not He has went.
- We are writing, not We are wrote.
- The files were copied, not The files were copying, when the intended meaning is passive.
The irregular verb go makes the contrast visible: go is the base form, went is the simple past, and gone is the past participle.
What Are the Main Types of Verb Phrases?
The main types are simple, progressive, perfect, perfect progressive, modal, passive, and combinations of these categories. A single verb phrase can express several categories at once, as may have been delayed expresses modal meaning, perfect aspect, and passive voice.
| Type | Grammatical form | Main meaning | Example |
|---|---|---|---|
| Simple | Main verb | Basic event or state | Lina works remotely |
| Progressive | be + present participle | Ongoing activity | Lina is working |
| Perfect | have + past participle | Earlier event related to a reference point | Lina has worked |
| Perfect progressive | have + been + present participle | Ongoing activity before a reference point | Lina has been working |
| Modal | modal + base verb | Possibility, ability, duty, or prediction | Lina might work |
| Passive | be + past participle | Recipient of an action is foregrounded | The report was submitted |
| Modal passive | modal + be + past participle | Possible or required passive event | The report must be submitted |
Simple Verb Phrases
A simple verb phrase may contain only a lexical verb:
- The children played.
- Water boils at 100°C at sea level.
- Nadia understands the problem.
In questions, negatives, and emphatic statements, do, does, or did can operate as an auxiliary:
- Do you understand?
- She does not agree.
- I did finish the report.
The main verb remains in the base form after do: did finish, not did finished.
Progressive Verb Phrases
Progressive phrases use a form of be plus a present participle:
- I am reading the manual.
- They were repairing the roof.
- The company is expanding into Canada.
The progressive usually presents an event as ongoing, temporary, or in progress around a reference time. Stative verbs such as know, believe, and own generally do not appear naturally in the progressive in their ordinary meanings. I know the answer is normal; I am knowing the answer is not.
Perfect Verb Phrases
Perfect phrases use have, has, or had plus a past participle:
- She has completed the course.
- We had left before sunrise.
- They will have finished by Friday.
Perfect aspect links an earlier event to a later reference point. It does not simply mean “past.” I have lived here for six years connects past residence with the present, while I lived there for six years usually presents the residence as finished.
Modal Verb Phrases
Modal auxiliaries include can, could, may, might, must, shall, should, will, and would. They express meanings such as ability, prediction, permission, probability, obligation, and hypothetical consequence.
- You must wear a helmet.
- The train may arrive late.
- Could we postpone the meeting?
- If demand rises, prices will increase.
A modal is followed by a base-form verb, even when the subject is third-person singular: She can drive, not She can drives.
Passive Verb Phrases
Passive phrases use a form of be plus a past participle:
- The invoice was paid.
- The samples are stored at 4°C.
- The policy will be reviewed next year.
Passive voice is useful when the action or result matters more than the agent, or when the agent is unknown. It is less effective when it hides responsibility in a sentence such as Mistakes were made.
What Is the Difference Between a Verb Phrase and a Phrasal Verb?
A verb phrase is a grammatical unit centered on a verb, while a phrasal verb is a lexical expression consisting of a verb plus a particle or preposition. Has reviewed is a verb phrase but not a phrasal verb. Has looked into is both a verb phrase and a phrase containing the phrasal verb look into.
| Phrasal-verb type | Object pattern | Example | Correct alternative |
|---|---|---|---|
| Intransitive | No direct object | The engine broke down | No object follows |
| Separable transitive | Object may follow or interrupt particle | Turn off the lamp | Turn the lamp off |
| Pronoun separation | Pronoun must interrupt particle | Turn it off | Not “turn off it” |
| Inseparable transitive | Object follows the complete expression | She ran into a colleague | Not “ran a colleague into” |
| Prepositional | Preposition keeps its object | They listened to the speaker | Not “listened the speaker” |
Phrasal-verb meaning can be unpredictable. Give up means “quit,” while give away can mean “donate” or “reveal.” Language learners often remember each expression as a vocabulary item rather than trying to calculate its meaning from the individual words.
Can a Verb Phrase Include an Object or Modifier?
A broad verb phrase can include a direct object, indirect object, complement, prepositional phrase, or adverb. These elements complete or modify the meaning of the verb, but they are not part of the strict auxiliary-and-main-verb chain.
Consider The engineer carefully tested the device in the laboratory:
- Strict verb phrase: tested
- Subject: The engineer
- Adverb: carefully
- Direct object: the device
- Location modifier: in the laboratory
Different grammatical traditions may group these constituents differently. The distinction matters when answering an assignment, because “identify the verb phrase” may mean identify only tested or the larger predicate carefully tested the device in the laboratory.
Verb Phrase Complements
Linking verbs require complements rather than ordinary direct objects:
- The soup smells delicious.
- Marcus became a doctor.
- The explanation seems reasonable.
In smells delicious, delicious describes the subject. In became a doctor, a doctor identifies the subject. These are subject complements, not direct objects.
How Do You Identify a Verb Phrase?
To identify a verb phrase, locate the central verb, collect its auxiliaries, include relevant modifiers or complements according to the required framework, and test whether the resulting unit can be replaced by a simpler verb phrase.
Use these steps:
- Find the lexical verb. Ask what action, event, or state the clause expresses.
- Look to the left for auxiliaries. Collect forms of be, have, do, and modal verbs.
- Check the verb forms. Confirm that modals take base forms, have takes past participles, and progressive be takes -ing forms.
- Decide the framework. Stop at the main verb for a strict analysis; include objects and modifiers for a broad predicate analysis.
- Apply substitution. Replace the suspected unit with runs, happened, or another simple verb and check whether the clause remains structurally sound.
Example:
The package will probably be delivered tomorrow.
Strict verb phrase: will be delivered.
Broad predicate: will probably be delivered tomorrow.
Substitution: The package arrives tomorrow.
The substitution test is useful but not infallible. Some modifiers attach outside the verb phrase, and a replacement may preserve structure while changing important meaning.
How Do Verb Phrases Work in Questions and Negatives?
Auxiliary verbs move before the subject in many questions, and not follows the first auxiliary in negative clauses. When no auxiliary is present in the simple present or past, English inserts do, does, or did.
| Statement | Question | Negative |
|---|---|---|
| She is waiting | Is she waiting? | She is not waiting |
| They have arrived | Have they arrived? | They have not arrived |
| Omar can swim | Can Omar swim? | Omar cannot swim |
| You like tea | Do you like tea? | You do not like tea |
| He visited Paris | Did he visit Paris? | He did not visit Paris |
Only the first auxiliary moves in a question: Has she been working? The phrase been working stays together. In a negative, not follows the first auxiliary: She has not been working.
Which Verb Phrase Errors Occur Most Often?
The most common errors involve incorrect forms after auxiliaries, missing auxiliaries, misplaced particles, and confusion between active and passive voice. Correcting the first auxiliary relationship usually fixes the entire chain.
| Incorrect form | Correct form | Reason |
|---|---|---|
| He has went home | He has gone home | Have requires a past participle |
| They will writing later | They will write later | A modal requires the base form |
| She been studying | She has been studying | Finite auxiliary has is missing |
| The files were deleted by accident | The files were deleted by accident | Passive requires a past participle |
| Turn off it | Turn it off | Pronoun objects split separable phrasal verbs |
| I ran an old friend into | I ran into an old friend | Run into is inseparable in this meaning |
| She does not likes jazz | She does not like jazz | Does carries tense and agreement |
| The report is completed yesterday | The report was completed yesterday | Past time requires past-tense was |
A useful editing rule is to inspect every verb chain from left to right. Identify the finite verb first, then verify the form selected by each auxiliary that follows.
Are Infinitives and Participles Verb Phrases?
Infinitives and participles can form non-finite verb phrases, but they cannot independently express tense and agreement in the same way as a finite clause. To reduce costs is an infinitival phrase, while reducing costs is a participial phrase.
Examples include:
- To finish on time requires careful planning.
- The manager hopes to finish on time.
- Having completed the audit, the team issued its report.
- The workers completing the audit need access to the database.
The classification depends on the grammatical tradition. Some school grammars label to finish on time an infinitive phrase; many modern syntactic analyses treat it as a non-finite verb phrase headed by finish. The important distinction is that to finish does not mark present or past tense.
How Should Writers Use Verb Phrases?
Writers should select the shortest verb phrase that expresses the intended time, aspect, voice, and degree of certainty. Long chains are sometimes necessary, but unnecessary passives, nominalizations, and progressive forms can obscure the actor and delay the main point.
Compare:
- The committee will be conducting a review of the policy.
- The committee will review the policy.
The first form emphasizes an activity expected to be in progress. The second is more direct and usually better for instructions or executive summaries.
Use a longer phrase when its grammatical information matters:
- By June, the team will have completed the migration.
- The medication must be stored below 25°C.
- The building is being inspected after the earthquake.
Professional editing should not eliminate every auxiliary. The goal is precision, not maximum brevity.
Expert Rules of Thumb
- Keep the finite verb close to the subject. Readers process The analyst has identified more easily than a sentence that inserts several parenthetical phrases before has.
- Treat passive voice as a choice, not an error. Passive wording is appropriate when the recipient or result is more important than the agent.
- Separate grammatical auxiliaries from lexical verb particles. In has given up, has and given form the auxiliary chain, while up belongs to the phrasal verb give up.
- Do not count words to diagnose complexity. A five-word phrase can be clearer than a three-word phrase if it accurately marks time and voice.
What Is the Difference Between a Verb Phrase and a Predicate?
A strict verb phrase may contain only the verb group, whereas a predicate includes everything in the clause except the subject. In The technician has repaired the machine carefully, the strict verb phrase is has repaired, while the predicate is has repaired the machine carefully.
| Analysis level | Subject | Verb group | Remaining predicate material |
|---|---|---|---|
| Strict | The technician | has repaired | the machine carefully |
| Broad predicate | The technician | has repaired the machine carefully | None |
| Linking clause | The room | feels | unusually cold |
| Passive clause | The machine | was repaired | by the technician |
This difference explains apparently conflicting answers in grammar resources. A resource focused on morphology isolates the verb forms; a resource focused on clause structure includes the verb’s dependents.
FAQ
Can one sentence contain two verb phrases?
Yes. A sentence with multiple clauses can contain multiple verb phrases. In When the alarm rang, the guards had already left, rang belongs to the subordinate clause and had already left belongs to the main clause. A compound sentence can also contain coordinated phrases, as in Mina cooked and Leo washed the dishes.
Is “has been running” a verb phrase?
Yes. Has been running is a strict verb phrase containing the perfect auxiliary has, the progressive auxiliary been, and the main verb running. In a broad analysis, an object or modifier may be added, as in has been running a marathon in the rain.
Is every group of verbs a verb phrase?
No. A group of verbs may belong to separate clauses. In I think she left, think heads the main clause and left heads a subordinate clause. By contrast, might have left is one verb phrase because the auxiliaries combine with a single lexical verb inside one clause.
Can a verb phrase begin with “to”?
Yes. To compare the results is a non-finite infinitival verb phrase in many linguistic analyses. The phrase has no finite tense marker, so it cannot independently function as the finite predicate of a standard declarative clause.
How many auxiliary verbs can English use together?
Standard English can combine up to four auxiliaries before a lexical verb in a highly marked chain such as might have been being tested. Ordinary writing rarely needs the full sequence, and shorter active alternatives are often easier to understand.
Does a verb phrase always contain an auxiliary?
No. Walked, sings, and understand are complete one-word verb phrases. Auxiliary verbs appear when English marks categories such as progressive aspect, perfect aspect, passive voice, modality, negation, or emphatic support.
Conclusion
A verb phrase combines a main verb with auxiliary verbs and, under a broader definition, the objects, complements, and modifiers that complete its predicate. Understanding auxiliary order, verb forms, tense, aspect, voice, phrasal verbs, and strict-versus-broad analysis makes verb phrase definition usage and examples easier to apply in grammar study, editing, and everyday writing.
