Finite and Non-finite Verbs: Definition, Types & Examples
Finite and Non-finite Verbs: Definition, Types, Rules, Examples and Differences
Finite and non-finite verbs are important concepts in English grammar. Understanding the difference between finite and non-finite verbs helps learners construct grammatically correct sentences, identify clauses, understand verb forms, and improve both spoken English and written English.
In this comprehensive guide, we will learn the definition of finite verbs, types of non-finite verbs, rules, examples, differences, and common mistakes.
What Is a Verb?
A verb is a word that expresses an action, occurrence, or state of being.
Examples:
- She writes every day.
- They played football.
- He is happy.
- We are learning English.
- I want to improve my speaking skills.
Verbs can be broadly studied as finite verbs and non-finite verbs.
What Is a Finite Verb?
A finite verb is a verb that is limited by tense, person, and number. It usually functions as the main verb of a clause and changes according to the subject or tense.
Examples:
- I work every day.
- She works every day.
- They worked yesterday.
- He worked yesterday.
Notice how the verb changes:
work → works → worked
Therefore, these are finite verbs.
Simple Definition
A finite verb is a verb that shows tense and agrees with the subject in person or number where applicable.
Examples of Finite Verbs
Consider these sentences:
1. She plays tennis.
plays → Finite verb
It changes according to the subject:
- I play tennis.
- She plays tennis.
- They play tennis.
2. He went to school.
went → Finite verb
It shows past tense.
3. They are happy.
are → Finite verb
The verb are changes according to the subject:
- I am happy.
- He is happy.
- They are happy.
What Is a Non-finite Verb?
A non-finite verb is a verb form that does not change according to the subject or tense.
Non-finite verbs do not normally function as the main finite verb of a clause.
Examples:
- to read
- to write
- reading
- writing
- written
- broken
Examples in sentences:
- I want to learn English.
- Reading is a good habit.
- The broken chair needs repair.
Here, to learn, reading, and broken are non-finite verb forms.
Types of Non-finite Verbs
There are three major categories of non-finite verbs:
- Infinitives
- Gerunds
- Participles
Let’s examine each one.
1. Infinitives
An infinitive is generally formed using:
to + base form of the verb
Examples:
- to eat
- to drink
- to speak
- to learn
- to write
- to study
- to play
Examples in sentences:
- I want to learn English.
- She decided to study harder.
- They came to help us.
- He wants to become a teacher.
To-infinitive
The most common infinitive form is the to-infinitive.
to + V1
Examples:
- to go
- to come
- to read
- to speak
- to work
Bare Infinitive
Sometimes an infinitive is used without “to”. This is called a bare infinitive.
Examples:
- Let me go.
- You must study.
- I saw him run.
- She made me laugh.
Here, go, study, run, laugh are bare infinitives.
2. Gerunds
A gerund is the -ing form of a verb that functions as a noun.
Examples:
- Reading is useful.
- Swimming is good exercise.
- I enjoy singing.
- Learning English takes practice.
In these sentences, the words reading, swimming, singing, and learning function as nouns.
Easy Rule
Verb + -ing functioning as a noun = Gerund
More Examples:
- Dancing is my hobby.
- Walking is good for your health.
- I enjoy playing cricket.
- She loves cooking.
3. Participles
Participles are non-finite verb forms that can function as adjectives or form part of verb phrases.
There are two main types:
A. Present Participle
The present participle usually ends in -ing.
Examples:
- running
- singing
- smiling
- crying
- dancing
Examples:
- The crying baby needs milk.
- The smiling girl is my daughter.
- I saw a running horse.
Here, the participles describe nouns.
B. Past Participle
The past participle is usually the third form (V3) of a verb.
Examples:
- written
- broken
- eaten
- spoken
- finished
- taken
- gone
Examples:
- The broken window needs repair.
- The written answer was correct.
- The finished project was submitted.
Finite vs Non-finite Verbs
Understanding the difference between finite and non-finite verbs is essential for learning English grammar.
| Finite Verb | Non-finite Verb |
|---|---|
| Shows tense | Does not show tense by itself |
| Can change according to the subject | Does not change according to the subject |
| Can function as the main verb | Cannot normally function as the main finite verb alone |
| Forms the core of a finite clause | Can function as a noun, adjective, or part of a verb phrase |
| Example: works | Example: to work |
| Example: worked | Example: working |
| Example: is | Example: written |
Compare These Sentences
Example 1
She wants to learn English.
- wants → Finite verb
- to learn → Non-finite verb
The verb wants agrees with the subject she and shows present tense.
Example 2
They enjoyed playing cricket.
- enjoyed → Finite verb
- playing → Non-finite verb / gerund
The verb enjoyed shows past tense.
Example 3
Reading books improves vocabulary.
- Reading → Non-finite verb / gerund
- improves → Finite verb
Reading books functions as the subject of the sentence.
Example 4
The boy is running.
- is → Finite verb
- running → Present participle
Together, is running forms the verb phrase.
Finite and Non-finite Verbs in Clauses
A clause normally contains a subject and a verb. Finite and non-finite verb forms can appear within clauses.
Example:
When she arrived, I started working.
- arrived → Finite verb
- started → Finite verb
- working → Non-finite verb
Another example:
To learn English, you must practice every day.
- to learn → Non-finite verb
- must practice → Finite verb phrase
How to Identify a Finite Verb
Use these simple questions:
Step 1: Does the verb show tense?
If yes, it is probably finite.
She worked yesterday.
worked → Finite
Step 2: Does the verb change according to the subject?
He plays.
They play.
The form changes, so it is finite.
Step 3: Can it function as the main verb of the clause?
She works hard.
works is the main finite verb.
How to Identify a Non-finite Verb
Look for these common forms:
Infinitive
to + V1
- to read
- to speak
- to write
Gerund
V-ing functioning as a noun
- Reading is useful.
- I enjoy swimming.
Participle
V-ing or V3 functioning as an adjective or part of a verb phrase
- the crying baby
- the broken glass
- She is running.
Important Difference Between Gerund and Present Participle
Both gerunds and present participles usually end in -ing, but their functions are different.
Gerund = noun function
Swimming is good exercise.
Here, swimming is the subject of the sentence.
Present Participle = adjective/verb-phrase function
The swimming boy is my brother.
Here, swimming describes the boy.
Another example:
She is swimming.
Here, swimming is a present participle forming the verb phrase is swimming.
Remember:
Gerund = -ing form used as a noun
Present participle = -ing form used as an adjective or as part of a verb phrase
Common Mistakes
Mistake 1: Treating every -ing word as a gerund
Not every -ing form is a gerund.
❌ The boy is gerund.
Instead:
The boy is running.
running → Present participle
Mistake 2: Thinking “to” always indicates an infinitive
Usually to + V1 is an infinitive:
- to learn
- to speak
- to work
But to can also function as a preposition.
Example:
I look forward to meeting you.
Here, to is a preposition, so meeting is a gerund.
