Verbs can take different forms depending on how they function in a sentence. One important distinction in English grammar is between finite and non-finite verbs. A finite verb changes according to the subject or tense, while a non-finite verb does not show tense or change according to the subject.
For example, in She works every day, works is a finite verb because its form agrees with the subject and shows present tense. In She wants to work today, to work is non-finite because it does not change according to the subject or indicate tense by itself. Recognizing this difference can make it easier to understand how verbs function within clauses and sentences.
In this guide, you will learn what finite and non-finite verbs are, how to identify them, and how they differ. You will also explore the main types of non-finite verbs—including infinitives, gerunds, and participles—with clear examples and practical exercises.

What Are Finite Verbs?
A finite verb is a verb form that shows tense and functions as part of the main verb phrase of a clause. Finite verbs are also connected to the subject of the clause and, in some forms, change according to the subject’s person or number.
For example:
-
She works at a school.
-
They work at a school.
-
She worked yesterday.
In the first two sentences, works and work are finite verbs in the present tense. Their forms depend on the subject. In the third sentence, worked is finite because it places the action in the past.
Main Features of Finite Verbs
Finite verbs have several important characteristics:
-
They show tense.
He plays football.
He played football. -
They are associated with a subject.
Sara reads every evening. -
They may change according to person or number.
I work from home.
She works from home. -
Every independent clause normally contains a finite verb.
The children are playing outside.
In The children are playing outside, are is the finite verb because it carries present tense and agrees with the plural subject the children. Playing is a non-finite participle and does not carry tense by itself.
Finite Verbs in Verb Phrases
A finite verb is not always the main lexical verb. When a verb phrase contains an auxiliary verb, the first auxiliary carries the finite features.
Consider these examples:
-
She is studying English.
-
They have finished their homework.
-
He was waiting for the bus.
-
We will visit them tomorrow.
In these sentences, is, have, was, and will are finite. The following forms—studying, finished, waiting, and visit—do not themselves carry the tense of the clause.
Understanding this point is especially useful because a sentence may contain several verb forms, but not every verb form is finite.
Finite Verb Examples
Finite verbs can appear in the present, past, or future and may occur as main verbs or auxiliary verbs. The following examples show how finite verbs function in different sentences.
| Sentence | Finite Verb | Explanation |
|---|---|---|
| She writes every day. | writes | Shows present tense and agrees with she. |
| They write every day. | write | Shows present tense with a plural subject. |
| Ali visited his friend yesterday. | visited | Places the action in the past. |
| We enjoy English lessons. | enjoy | Functions as the finite verb in the present tense. |
| He is reading a book. | is | Carries present tense and agrees with he. |
| They were playing outside. | were | Carries past tense and agrees with they. |
| Sara has completed her homework. | has | Carries present tense and agrees with Sara. |
| The students have finished the test. | have | Carries present tense with a plural subject. |
| I can help you. | can | Functions as the finite modal verb. |
| We will travel tomorrow. | will | Functions as the finite modal auxiliary in the verb phrase. |
Examples of Finite Verbs in the Present Tense
In the simple present tense, finite verbs can change according to the subject.
-
I play football.
-
You play football.
-
He plays football.
-
She teaches English.
-
They teach English.
Notice how play becomes plays with the third-person singular subject he. Similarly, teach becomes teaches with she. These changes show subject–verb agreement.
Examples of Finite Verbs in the Past Tense
Finite verbs can also place an action or state in the past.
-
She walked to school.
-
They watched a movie.
-
I saw him yesterday.
-
He wrote a letter.
-
We were tired after the journey.
In these examples, walked, watched, saw, wrote, and were are finite verb forms because they carry past tense.
Finite Verbs with Auxiliary Verbs
When a verb phrase contains one or more auxiliary verbs, the finite element occurs at the beginning of the verb phrase.
-
She is working today.
-
They are learning English.
-
He has completed the assignment.
-
We were waiting outside.
-
She will arrive tomorrow.
-
They can solve the problem.
In these examples, is, are, has, were, will, and can are finite. The verb forms that follow them—working, learning, completed, waiting, arrive, and solve—are non-finite within these verb phrases.
More Finite Verb Examples in Sentences
Here are a few additional examples:
-
The baby cries at night.
-
My parents live in the city.
-
John bought a new laptop.
-
The children were laughing.
-
Maria has prepared dinner.
-
We should leave now.
-
The train arrived late.
-
He does understand the problem.
-
You must follow the instructions.
-
The teacher is explaining the lesson.
A useful way to recognize a finite verb is to look for the verb element that carries tense or modality and, where applicable, shows agreement with the subject. This becomes especially important when a sentence contains more than one verb form.
How to Identify Finite Verbs
To identify a finite verb in a sentence, look for the verb element that carries tense or modality and is connected to the subject of the clause. In simple verb forms, the finite verb may also change according to the person or number of the subject.
Here are some useful ways to identify finite verbs.
1. Check Whether the Verb Shows Tense
A finite verb places a situation in time through the tense system.
-
She works in an office.
-
She worked in an office.
The change from works to worked shows a change from present to past. Both are finite verb forms.
2. Check for Subject-Verb Agreement
In the simple present tense, many finite verbs change when the subject changes from a non-third-person-singular subject to a third-person singular one.
-
I play tennis.
-
They play tennis.
-
He plays tennis.
The change from play to plays helps show that the verb is finite.
However, not every finite verb visibly changes with every subject. For example, worked remains the same in I worked and they worked. It is still finite because it carries past tense.
3. Look at the First Verb in a Verb Phrase
When a verb phrase contains auxiliary verbs, the first auxiliary is normally the finite element.
-
She is reading a novel.
-
They have completed the work.
-
He was sleeping.
-
We will visit the museum.
-
You can leave now.
Here, is, have, was, will, and can are finite. The following verb forms are non-finite within their respective verb phrases.
4. Look for Modal Verbs
Modal verbs such as can, could, may, might, shall, should, will, would, and must function as finite verbs when they head a verb phrase.
-
She can swim.
-
You should study.
-
They might arrive late.
-
We must leave now.
The verbs that follow the modals—swim, study, arrive, and leave—are bare infinitive forms and are non-finite in these constructions.
5. Identify the Clauses in Longer Sentences
A sentence can contain more than one finite verb when it contains more than one clause.
Consider:
I know that she works at a hospital.
There are two finite verbs:
-
know — finite verb of the main clause
-
works — finite verb of the subordinate clause
Similarly:
When he arrived, we were eating dinner.
The finite verbs are:
-
arrived — finite verb of the subordinate clause
-
were — finite verb of the main clause
The form eating is non-finite.
Quick Test for Finite Verbs
When examining a verb, ask these questions:
-
Does it carry tense or modality?
-
Is it associated with the subject of a clause?
-
Does it show subject agreement where the verb form allows it?
-
If there is a multi-word verb phrase, which verb comes first and carries the finite grammatical information?
For example:
The children have been playing outside.
The complete verb phrase is have been playing, but have is the finite element. It carries present tense and agrees with the plural subject the children. Been and playing are non-finite forms.
Using these tests makes it easier to distinguish finite verbs from the non-finite verb forms that often appear alongside them.
What Are Non-Finite Verbs?
A non-finite verb is a verb form that does not function as the finite verb of a clause. It does not carry tense or modality by itself and does not change its form to agree with the subject. Non-finite verbs commonly appear as infinitives, gerunds, and participles.
For example:
-
She wants to learn English.
-
Swimming is good exercise.
-
The children are playing outside.
-
He has finished his homework.
In these sentences, to learn, swimming, playing, and finished are non-finite verb forms. They do not independently establish the tense of their clauses.
Main Features of Non-Finite Verbs
Non-finite verbs have several important characteristics:
-
They do not carry tense by themselves.
She wants to travel.
The infinitive to travel does not tell us when the traveling happens. -
They do not show subject-verb agreement.
I want to study.
She wants to study.
They want to study.
The form to study remains unchanged even though the subject changes. -
They often occur alongside finite verbs.
He is reading a book.
Here, is is finite, while reading is non-finite. -
They can perform different functions in sentences.
Depending on the form and construction, non-finite verbs can form part of a verb phrase or function in positions commonly occupied by nouns, adjectives, or modifiers.
Non-Finite Verbs Do Not Carry Tense Independently
One of the easiest ways to understand non-finite verbs is to compare them across sentences.
Consider the infinitive to work:
-
I wanted to work yesterday.
-
I want to work today.
-
I will want to work tomorrow.
The form to work remains unchanged. The time reference of each sentence comes from the finite verb phrase—wanted, want, and will want—rather than from to work itself.
The same principle applies to other non-finite forms:
-
She is reading a book.
-
She was reading a book.
-
She will be reading a book.
The participle reading remains the same. The finite part of the verb phrase changes to express the grammatical tense or modality.
Finite and Non-Finite Verbs in the Same Sentence
Finite and non-finite verbs frequently appear together.
She wants to learn Spanish.
-
wants — finite
-
to learn — non-finite
They are playing football.
-
are — finite
-
playing — non-finite
He has completed the assignment.
-
has — finite
-
completed — non-finite
A useful rule to remember is that finite verbs carry the grammatical tense or modality of a clause, while non-finite forms do not do so independently.
The three main types of non-finite verb forms are infinitives, gerunds, and participles. Each has a different role and pattern of use in English sentences.
Types of Non-Finite Verbs
There are three main types of non-finite verbs in English: infinitives, gerunds, and participles. These verb forms do not carry tense or show subject-verb agreement by themselves, but they perform different functions in sentences.
1. Infinitives
An infinitive is the base form of a verb used in a non-finite construction. It commonly appears with to, although infinitives can also occur without to after modal verbs and certain other constructions.
Examples:
-
I want to learn English.
-
She decided to leave early.
-
They hope to visit us soon.
-
He can swim well.
-
You should study more.
In the first three examples, to learn, to leave, and to visit are to-infinitives. In the last two, swim and study are bare infinitives following modal verbs.
Infinitives can perform several functions:
-
To exercise regularly is beneficial.
-
She wants to travel.
-
We have some work to finish.
The infinitive does not carry the tense of the clause. Instead, the finite verb or verb phrase provides the grammatical tense or modality.
2. Gerunds
A gerund is an -ing form of a verb used in a noun-like position.
Examples:
-
Reading improves your vocabulary.
-
She enjoys cooking.
-
Swimming is good exercise.
-
They discussed moving to another city.
Although gerunds come from verbs, they can occupy positions typically associated with noun phrases, such as the subject or object of a clause.
Compare:
-
Swimming is enjoyable.
-
She enjoys swimming.
In the first sentence, swimming functions as the subject. In the second, it functions as the complement of enjoys. In both cases, it is a non-finite -ing form.
3. Participles
A participle is a non-finite verb form that can occur in verb phrases or function as a modifier. English commonly uses present participles and past participles.
Present Participles
Present participles usually end in -ing.
Examples:
-
She is reading a novel.
-
They were playing outside.
-
The crying baby needed attention.
In is reading and were playing, the participles form part of larger verb phrases. The finite verbs are is and were, while reading and playing are non-finite.
Past Participles
Past participles often end in -ed for regular verbs, although irregular verbs can have forms such as written, broken, eaten, and seen.
Examples:
-
She has finished her work.
-
The window was broken.
-
I have written the letter.
-
The damaged car was repaired.
In these examples, finished, broken, written, and damaged are past participles.
Infinitives, Gerunds, and Participles at a Glance
| Type | Common Form | Example | Function in the Example |
|---|---|---|---|
| To-infinitive | to + base verb | She wants to study. | Complement of wants |
| Bare infinitive | base verb | She can study. | Follows a modal |
| Gerund | verb + -ing | Studying helps me learn. | Subject |
| Present participle | verb + -ing | She is studying. | Part of a verb phrase |
| Past participle | -ed or irregular form | She has studied. | Part of a verb phrase |
Gerunds and present participles both use the -ing form, so their appearance alone does not tell you their function. A gerund occupies a noun-like position, while a participle typically forms part of a verb phrase or functions as a modifier.
Understanding these three forms makes it much easier to recognize non-finite verbs and distinguish them from finite verbs in complete sentences.
Non-Finite Verb Examples
Non-finite verbs can appear as infinitives, gerunds, present participles, or past participles. The examples below show how these forms work in different sentences.
| Sentence | Non-Finite Verb | Type |
|---|---|---|
| She wants to study English. | to study | Infinitive |
| We decided to leave early. | to leave | Infinitive |
| He can drive a car. | drive | Bare infinitive |
| Reading improves vocabulary. | reading | Gerund |
| She enjoys painting. | painting | Gerund |
| They are playing outside. | playing | Present participle |
| He was waiting for the bus. | waiting | Present participle |
| She has completed her work. | completed | Past participle |
| We have seen that movie. | seen | Past participle |
| The broken chair needs repair. | broken | Past participle |
Examples of Infinitives
Infinitives often follow another verb, adjective, or certain noun constructions.
-
I hope to see you soon.
-
She wants to become a doctor.
-
We decided to stay at home.
-
He promised to help me.
-
They plan to travel next month.
The infinitives to see, to become, to stay, to help, and to travel do not carry the tense of their clauses. The finite verbs hope, wants, decided, promised, and plan do that grammatical work.
Examples of Gerunds
Gerunds are -ing forms used in noun-like positions.
-
Walking is good exercise.
-
She enjoys reading novels.
-
Learning English takes practice.
-
They discussed moving abroad.
-
He avoids driving at night.
The highlighted words are derived from verbs, but they occupy positions commonly filled by noun phrases.
Examples of Present Participles
Present participles also end in -ing, but their grammatical function differs from that of gerunds.
-
She is writing an email.
-
They were watching television.
-
The children came running into the room.
-
I saw a smiling child.
-
We spent the afternoon talking.
In is writing and were watching, the participles form part of larger verb phrases. In examples such as smiling child, the participle modifies a noun.
Examples of Past Participles
Past participles are commonly used in perfect constructions, passive constructions, and as modifiers.
-
She has finished her homework.
-
They have written the report.
-
The door was closed by the guard.
-
The fallen leaves covered the ground.
-
We repaired the damaged table.
Regular past participles often end in -ed, while irregular verbs may have forms such as written, fallen, broken, eaten, and seen.
Sentences with More Than One Non-Finite Verb
A sentence can contain several non-finite verb forms.
She wants to start learning Spanish.
-
wants — finite verb
-
to start — non-finite infinitive
-
learning — non-finite -ing form
Another example:
He has decided to stop working at night.
-
has — finite verb
-
decided — non-finite past participle within has decided
-
to stop — non-finite infinitive
-
working — non-finite -ing form
These examples show why it is important to examine the function of each verb form in the sentence rather than simply counting the number of words that look like verbs.
Finite vs Non-Finite Verbs
The main difference between finite and non-finite verbs is that a finite verb carries the grammatical tense or modality of a clause, while a non-finite verb does not do so independently. Finite verbs are associated with the subject of a clause, whereas non-finite forms do not show subject-verb agreement.
Consider this sentence:
She wants to learn English.
Here, wants is finite because it carries present tense and agrees with the singular subject she. To learn is non-finite because its form does not change according to the subject or independently establish the tense of the clause.
Difference Between Finite and Non-Finite Verbs
| Feature | Finite Verbs | Non-Finite Verbs |
|---|---|---|
| Tense | Carry tense or modality | Do not carry tense or modality independently |
| Subject agreement | May change according to person or number | Do not change to agree with the subject |
| Role in a clause | Serve as the finite element of a clause | Cannot serve as the finite element by themselves |
| Common forms | works, worked, is, has, can | to work, working, worked/written |
| Main types | Main verbs and auxiliaries used finitely | Infinitives, gerunds, and participles |
| Example | She works here. | She wants to work here. |
Finite and Non-Finite Verbs in Paired Examples
The following examples make the difference easier to see.
1. She works every day.
-
works — finite verb
The verb carries present tense and agrees with the third-person singular subject she.
2. She wants to work every day.
-
wants — finite verb
-
to work — non-finite verb
The finite verb changes if the subject changes:
They want to work every day.
Here, wants changes to want, but to work remains unchanged.
Compare Subject Changes
Look at how the finite verb changes while the non-finite form stays the same:
-
He likes to read.
-
They like to read.
-
She likes to read.
The finite forms likes and like change according to the subject. The non-finite infinitive to read remains unchanged.
Compare Tense Changes
Finite and non-finite forms also behave differently when the tense changes:
-
She wants to travel.
-
She wanted to travel.
-
She will want to travel.
The finite part changes from wants to wanted to will want. The non-finite form to travel remains the same.
Another example is:
-
She is studying English.
-
She was studying English.
-
She will be studying English.
The grammatical tense or modality is expressed by the finite element at the beginning of the verb phrase, while studying remains a non-finite participle.
Can a Sentence Have Both Finite and Non-Finite Verbs?
Yes. Finite and non-finite verbs frequently occur together in the same sentence.
For example:
The students are trying to complete the assignment.
This sentence contains:
-
are — finite verb
-
trying — non-finite present participle
-
to complete — non-finite infinitive
Another example:
She has decided to start exercising.
This sentence contains:
-
has — finite verb
-
decided — non-finite past participle within the perfect construction
-
to start — non-finite infinitive
-
exercising — non-finite -ing form
Quick Way to Remember the Difference
A simple way to remember the distinction is:
Finite = carries the clause’s tense or modality.
Non-finite = does not carry the clause’s tense or modality by itself.
Do not rely only on whether a word looks like a verb. Instead, examine what the verb form is doing in the clause. This is particularly important with -ing forms, past participles, infinitives, and multi-word verb phrases.
How to Identify Finite and Non-Finite Verbs in Sentences
When a sentence contains several verb forms, identifying which ones are finite and which are non-finite can seem difficult. A useful approach is to examine the sentence clause by clause and determine which verb element carries tense or modality in each clause.
Follow these steps.
Step 1: Find All the Verb Forms
First, identify all the words or phrases that function as verbs.
For example:
She wants to learn English.
The verb forms are:
-
wants
-
to learn
Now you can examine each one separately.
Step 2: Find the Finite Verb
Look for the verb element that carries tense or modality and belongs to the clause.
In:
She wants to learn English.
Wants is finite because it carries present tense and agrees with the third-person singular subject she.
If we change the subject, the form can change:
-
She wants to learn English.
-
They want to learn English.
This subject agreement confirms that wants/want is finite.
Step 3: Identify the Non-Finite Forms
Next, look for infinitives, gerunds, and participles that do not independently carry the tense or modality of the clause.
In:
She wants to learn English.
To learn is non-finite. It remains unchanged when the subject or tense of the main clause changes:
-
She wants to learn English.
-
They want to learn English.
-
She wanted to learn English.
The finite verb changes, while to learn stays the same.
Step 4: Check Multi-Word Verb Phrases Carefully
A verb phrase may contain several verb forms, but only one element is finite.
Consider:
They have been studying English.
The verb phrase is have been studying.
-
have — finite
-
been — non-finite past participle
-
studying — non-finite present participle
The first auxiliary, have, carries present tense and agrees with the subject.
Another example:
She was reading a book.
-
was — finite
-
reading — non-finite present participle
Step 5: Check Each Clause Separately
A sentence with more than one clause can contain more than one finite verb.
For example:
I know that she enjoys reading novels.
The sentence contains two clauses:
Main clause: I know
Subordinate clause: she enjoys reading novels
The verb forms are:
-
know — finite
-
enjoys — finite
-
reading — non-finite
There are two finite verbs because there are two clauses with their own finite verb elements.
Practice Identifying Finite and Non-Finite Verbs
Study the following examples:
| Sentence | Finite Verb | Non-Finite Verb(s) |
|---|---|---|
| She wants to leave. | wants | to leave |
| They are playing football. | are | playing |
| He has finished his work. | has | finished |
| We enjoy reading books. | enjoy | reading |
| She can speak French. | can | speak |
| They decided to travel abroad. | decided | to travel |
| He was trying to open the door. | was | trying, to open |
| She has started learning Spanish. | has | started, learning |
| I know that he likes swimming. | know, likes | swimming |
| They will try to finish the project. | will | try, to finish |
A Simple Identification Formula
You can use this quick process whenever you analyze a sentence:
Find the clauses → locate the verb phrases → identify the tense- or modality-carrying element → classify the remaining verb forms.
For example:
The students have decided to start studying earlier.
The verb forms are:
-
have — finite
-
decided — non-finite past participle
-
to start — non-finite infinitive
-
studying — non-finite -ing form
By examining the grammatical role of each verb form instead of its appearance alone, you can identify finite and non-finite verbs much more accurately.
Conclusion
Understanding finite and non-finite verbs helps you see how different verb forms work together in English sentences. A finite verb carries the tense or modality of a clause and is associated with its subject, while a non-finite verb does not carry tense or show subject agreement independently.
Non-finite verbs include infinitives, gerunds, and participles. They often appear alongside finite verbs, as in She wants to learn English or They are studying grammar. Learning to identify the clauses and verb phrases in a sentence makes it much easier to tell these forms apart.
Practice identifying finite and non-finite verbs in different sentence patterns, especially sentences containing auxiliary verbs, infinitives, -ing forms, and past participles. With regular practice, recognizing the role of each verb form will become much easier.
Finite and Non-Finite Verbs FAQs
1. What is a finite verb?
A finite verb is a verb form that carries tense or modality and functions as the finite element of a clause. It is associated with a subject and may change according to person or number. For example, in She works every day, works is finite.
2. What is a non-finite verb?
A non-finite verb is a verb form that does not carry tense or modality independently and does not show subject-verb agreement. Infinitives, gerunds, and participles are the main types of non-finite verb forms.
3. What is the difference between finite and non-finite verbs?
The main difference is that finite verbs carry the grammatical tense or modality of a clause, while non-finite verbs do not do so independently. For example, in She wants to study, wants is finite and to study is non-finite.
4. What are the three main types of non-finite verbs?
The three main types are infinitives, gerunds, and participles. Examples include to read (infinitive), reading in Reading is useful (gerund), and reading in She is reading (present participle).
5. How do you identify a finite verb in a sentence?
Look for the verb element that carries tense or modality in its clause. In the simple present, it may also show agreement with the subject. In He plays football, plays is finite. In He is playing football, is is the finite element.
6. How do you identify a non-finite verb?
Look for an infinitive, gerund, or participle that does not independently carry the tense or modality of the clause. In They decided to leave, decided is finite and to leave is non-finite.
7. Is an infinitive a finite or non-finite verb?
An infinitive is a non-finite verb form. For example, to write in She wants to write a book does not change according to the subject and does not independently carry tense.
8. Is a gerund a finite or non-finite verb?
A gerund is a non-finite -ing form used in a noun-like position. For example, in Swimming is good exercise, swimming is a gerund and is non-finite.
9. Is a participle finite or non-finite?
Participles are non-finite verb forms. Present participles usually end in -ing, while past participles may end in -ed or have irregular forms such as written, seen, and broken.
10. Can a sentence contain both finite and non-finite verbs?
Yes. For example, in She wants to learn English, wants is finite and to learn is non-finite. It is very common for finite and non-finite verb forms to appear together.
11. Can a sentence have more than one finite verb?
Yes. A sentence containing multiple clauses can have multiple finite verbs. In I know that she works here, know is finite in the main clause and works is finite in the subordinate clause.
12. Is an -ing verb always non-finite?
An -ing verb form is non-finite, but its grammatical role can differ. It may be a gerund, as in Reading is enjoyable, or a present participle, as in She is reading. In the second example, is is the finite element and reading is non-finite.
