What Are Non-finite Verbs?
Non-finite verbs are verb forms that do not show tense or agree with the subject. They include gerunds, infinitives, and participles. Unlike finite verbs, non-finite verbs do not act as the main verb in a sentence.
| Finite Verb | Non-finite Verb |
|---|---|
| He plays football. (shows tense & subject) | Playing football is fun. (no subject or tense) |
| She danced yesterday. | She wants to dance. |
Introduction to the Three Types of Non-finite Verb
- Gerunds: "-ing" forms used as nouns (e.g., swimming)
- Infinitives: "to" + base verb (e.g., to swim)
- Participles: "-ing", "-ed", or irregular forms used as adjectives or verbals (e.g., swimming, swum)
Knowing the types of non-finite verbs helps you identify their roles in sentences. This is crucial for grammar questions in exams and for improving your English fluency.
Easy Examples of Non-finite Verbs
| Type | Function | Example |
|---|---|---|
| Gerund | Subject | Reading improves your mind. |
| Infinitive | Object | She loves to dance. |
| Participle (Present) | Adjective | The running water is cold. |
| Participle (Past) | Adjective | Baked bread is delicious. |
The Three Types of Non-finite Verb in Detail
1. Gerunds
A gerund is a verb form ending in “-ing” that acts as a noun. Gerunds can be subjects, objects, or complements in a sentence. Example: Singing relaxes me. “Singing” is the subject.
2. Infinitives
Infinitives are the “to” + base verb form (to study, to eat). Infinitives can act as nouns, adjectives, or adverbs. Example: I want to succeed. “To succeed” is the object.
3. Participles
Participles function as adjectives or as parts of verb phrases.
- Present Participles: end in “-ing” (e.g., The crying child)
- Past Participles: usually end in “-ed” or are irregular (e.g., boiled eggs, broken vase)
Why Non-finite Verbs Are Important
Non-finite verbs let you be concise and creative. They reduce word count, combine ideas smoothly, and add variety. In exams, you need to spot or use non-finite verb forms to get full marks in grammar sections.
Common Uses and Examples in Daily Life
Gerunds: “Swimming” in “Swimming is healthy.” Used as a noun.
Infinitives: “to win” in “He wants to win.” Used as an object.
Participles: “lost” in “The lost dog was found.” Used as an adjective.
You use non-finite verbs every day, sometimes without even noticing. They make sentences shorter and your meaning clearer.
Non-finite Verbs vs. Finite Verbs
A finite verb shows tense and matches a subject (e.g., She eats). A non-finite verb does not change for tense or subject (e.g., eaten, eating, to eat). This difference helps when analyzing or constructing sentences for school and competitive exams.
How to Identify Non-finite Verbs
- Look for verbs not changing with the subject or tense.
- Check if the verb acts as a noun, adjective, or adverb.
- Gerunds and present participles both end in “-ing”, but gerunds act as nouns, while participles act as adjectives.
Recognizing these forms improves editing, writing, and exam performance. For more practice, see our Finite and Non-finite Verbs Exercises.

FAQs on Understanding Non Finite Verbs in English Grammar
1. What are non-finite verbs in English grammar?
Non-finite verbs are verb forms that do not show tense or agree with the subject and cannot function as the main verb of a sentence. They are called non-finite because they do not change according to person, number, or time. The three main types of non-finite verbs are:
- Infinitives (to eat, to go)
- Gerunds (eating, swimming)
- Participles (eaten, going)
2. What are the three types of non-finite verbs?
The three types of non-finite verbs are infinitives, gerunds, and participles. Each type has a different function:
- Infinitive: base verb + “to” (to read) and can act as a noun, adjective, or adverb.
- Gerund: verb + -ing (reading) and functions as a noun.
- Participle: present (-ing) or past (-ed/-en) form used as adjectives or in verb phrases.
3. What is the difference between finite and non-finite verbs?
The main difference is that finite verbs show tense and agree with the subject, while non-finite verbs do not. A finite verb changes according to time and subject (e.g., “She writes a letter”), whereas a non-finite verb remains unchanged (e.g., “She likes to write letters”).
- Finite verbs act as the main verb of a clause.
- Non-finite verbs cannot stand alone as the main verb.
4. What is an infinitive and how is it used?
An infinitive is the base form of a verb usually preceded by “to” and is used as a noun, adjective, or adverb. The structure is to + base verb (to speak, to learn).
- As a noun: “To travel is my dream.”
- As an adjective: “She has a book to read.”
- As an adverb: “He came to help.”
5. What is a gerund and how do you identify it?
A gerund is a verb form ending in -ing that functions as a noun in a sentence. Although it looks like a present participle, a gerund acts as a subject, object, or complement.
- Subject: “Swimming is fun.”
- Object: “She enjoys reading.”
- Complement: “His hobby is painting.”
6. What is a participle and what are its types?
A participle is a verb form used as an adjective or to form verb tenses. There are two main types of participles:
- Present participle (-ing form): “The crying baby.”
- Past participle (-ed/-en form): “The broken glass.”
7. Can a non-finite verb be the main verb in a sentence?
No, a non-finite verb cannot function as the main verb of a complete sentence. A complete sentence requires a finite verb to show tense and agreement. For example:
- Incorrect: “She to go home.”
- Correct: “She wants to go home.”
8. How do non-finite verbs function in a sentence?
Non-finite verbs function as nouns, adjectives, or adverbs in a sentence. Their role depends on the type:

9. What are some common examples of non-finite verbs?

- Infinitive: “I want to learn English.”
- Gerund: “Jogging improves health.”
