Definition of Finite and Non-Finite Verbs
Verbs are the action words in a sentence, but they come in two main types: finite and non-finite. Understanding the difference is essential for constructing grammatically correct sentences.
Finite Verbs
A finite verb is a verb that shows tense (past, present, future) and agrees with the subject in number (singular or plural). It is the main verb in an independent clause and can stand alone as a complete thought. Finite verbs are essential because they indicate when an action happened and who or what performed the action. They are the core of any sentence.
For example, in the sentence “She walks to school,” the verb “walks” is finite because it is in the present tense and agrees with the singular subject “she.” Similarly, in “They walked to school,” “walked” is finite, showing past tense and agreeing with the plural subject “they.”
Non-Finite Verbs
A non-finite verb, on the other hand, does not show tense or agree with the subject. It cannot stand alone as the main verb of an independent clause. Instead, it functions as a noun, adjective, or adverb. Non-finite verbs come in three forms: infinitives, gerunds, and participles.
For instance, in the sentence “To swim is her passion,” “to swim” is a non-finite verb (infinitive) functioning as a noun (the subject of the sentence). In “Swimming is fun,” “swimming” is a non-finite verb (gerund) also functioning as a noun. And in “The broken window needs repair,” “broken” is a non-finite verb (participle) functioning as an adjective modifying “window.”
Structural Breakdown
The structure of finite and non-finite verbs differs significantly, impacting their role in sentence construction.
Finite Verb Structure
Finite verbs typically consist of a base form with inflections to indicate tense and agreement. Common inflections include:
- -s/es: Present tense, singular subject (e.g., he walks)
- -ed: Past tense (e.g., they walked)
- Auxiliary verbs (be, have, do) to form compound tenses (e.g., is walking, has walked, did walk)
- Modal verbs (can, could, will, would, should, may, might, must) (e.g., I will walk)
Finite verbs are the main indicators of time and agency within a sentence. They define the temporal context of the action and link it directly to the subject.
Non-Finite Verb Structure
Non-finite verbs have distinct structures depending on their type:
- Infinitives: to + base form (e.g., to walk, to eat, to sleep) or the base form alone (bare infinitive) often after modal verbs (e.g., I must go)
- Gerunds: base form + -ing (e.g., walking, eating, sleeping)
- Participles:
- Present Participles: base form + -ing (e.g., walking, eating, sleeping)
- Past Participles: usually ends in -ed, -en, -t, or irregularly (e.g., walked, eaten, slept)
Non-finite verb forms do not change based on the subject or tense. They derive their meaning from the context of the sentence and their function as nouns, adjectives, or adverbs.
Types of Finite Verbs
Finite verbs can be categorized based on their tense, voice, and mood.
Tense
Tense indicates the time of the action. The three main tenses are past, present, and future.
- Past Tense: Describes actions that happened in the past (e.g., I walked).
- Present Tense: Describes actions happening now or habitual actions (e.g., I walk).
- Future Tense: Describes actions that will happen in the future (e.g., I will walk).
Voice
Voice indicates whether the subject performs the action (active voice) or receives the action (passive voice).
- Active Voice: The subject performs the action (e.g., The dog chased the ball).
- Passive Voice: The subject receives the action (e.g., The ball was chased by the dog).
Mood
Mood indicates the manner in which the verb expresses the action or state. The primary moods are indicative, imperative, and subjunctive.
- Indicative Mood: States a fact or asks a question (e.g., I am walking. Are you walking?).
- Imperative Mood: Gives a command or makes a request (e.g., Walk!).
- Subjunctive Mood: Expresses a wish, possibility, or condition contrary to fact (e.g., I wish I were walking).
Types of Non-Finite Verbs
Non-finite verbs come in three main forms: infinitives, gerunds, and participles, each with its own function.
Infinitives
An infinitive is the base form of a verb, usually preceded by “to.” It can function as a noun, adjective, or adverb.
- Noun: To err is human.
- Adjective: I need a book to read.
- Adverb: She went to the store to buy milk.
A bare infinitive is an infinitive without “to,” often used after modal verbs (e.g., I can swim.) and certain verbs like *let*, *make*, *see*, *hear*, and *help*.
Gerunds
A gerund is a verb form ending in “-ing” that functions as a noun.
- Subject: Swimming is good exercise.
- Object: I enjoy reading.
- Complement: My favorite activity is hiking.
- Object of a Preposition: She is good at painting.
Participles
A participle is a verb form that can function as an adjective. There are two types of participles: present participles and past participles.
- Present Participles: End in “-ing” (e.g., walking, talking). They can describe an ongoing action or state (e.g., The walking man).
- Past Participles: Usually end in “-ed,” “-en,” “-t,” or irregularly (e.g., walked, eaten, built). They can describe a completed action or a state resulting from a completed action (e.g., The broken window).
Participles are also used to form continuous and perfect tenses (e.g., I am walking, I have walked).

Usage Rules
Proper usage of finite and non-finite verbs is crucial for clear and correct writing. Here are some key rules to follow.
Finite Verb Rules
- Every independent clause must have at least one finite verb.
- The finite verb must agree with the subject in number and person.
- The finite verb must be in the correct tense to indicate when the action occurred.
- Use auxiliary verbs to form compound tenses (e.g., has eaten, is walking).
- Use modal verbs to express possibility, necessity, or permission (e.g., can swim, must leave).
Non-Finite Verb Rules
- Non-finite verbs cannot stand alone as the main verb of an independent clause.
- Infinitives are often used after certain verbs (e.g., want to go, need to study).
- Gerunds function as nouns and can be used as subjects, objects, or complements.
- Participles function as adjectives and can modify nouns.
- Use present participles to describe ongoing actions or states.
- Use past participles to describe completed actions or states resulting from completed actions.
Specific Usage Notes
- Bare Infinitives: Use bare infinitives (without “to”) after modal verbs (e.g., can, could, will, would, should, may, might, must) and after verbs like let, make, see, hear, help.
- Gerunds vs. Infinitives: Some verbs can be followed by either a gerund or an infinitive, but the meaning may change (e.g., I remember swimming vs. I remember to swim).
- Participial Phrases: Participles can form phrases that modify nouns or verbs (e.g., Having finished his work, he went home).

Advanced Topics
For advanced learners, here are some more complex aspects of finite and non-finite verbs. These topics delve into finer points of grammar and usage, offering a deeper understanding of how verbs function in more intricate sentence structures.
Absolute Phrases
An absolute phrase modifies an entire clause or sentence, not just a single word. It usually consists of a noun or pronoun followed by a participle.
Example: The weather permitting, we will go for a hike.
In this sentence, “The weather permitting” is an absolute phrase that modifies the entire clause “we will go for a hike.” It provides context or a condition for the action in the main clause.
Reduced Relative Clauses
A reduced relative clause is a relative clause (which, who, that) where the relative pronoun and auxiliary verb have been omitted, leaving only a participle.
Example: The book written by Hemingway is a classic. (Original: The book that was written by Hemingway is a classic.)
Here, “written by Hemingway” is a reduced relative clause modifying “book.” The relative pronoun “that” and the auxiliary verb “was” have been removed, leaving only the past participle “written.”
Causative Verbs
Causative verbs (e.g., make, have, get, let) cause someone else to do something. They often involve bare infinitives or participles.
Example: I made him clean his room. (Bare infinitive after “make”)
In this sentence, “made” is a causative verb, and “clean” is a bare infinitive. The sentence means that I caused him to clean his room.
Verb Complementation
Verb complementation refers to the various structures that can follow a verb to complete its meaning. This can involve infinitives, gerunds, or that-clauses, and the choice often depends on the specific verb used.
Example: She decided to go to the party. (Infinitive complement)
Example: He admitted stealing the money. (Gerund complement)
Example: They believe that he is innocent. (That-clause complement)
Subjunctive Mood in Detail
The subjunctive mood expresses wishes, suggestions, requirements, or hypothetical situations. It often uses the base form of the verb (without “-s” for the third-person singular) and is commonly found in “that” clauses after verbs like “suggest,” “recommend,” “demand,” and “insist.”
Example: I suggest that he be present at the meeting.
Example: It is essential that she arrive on time.
FAQ
Here are some frequently asked questions about finite and non-finite verbs.
Q1: How can I easily identify a finite verb in a sentence?
A: Look for the verb that changes form based on the subject (singular or plural) and the tense (past, present, future). If the verb shows tense and agrees with the subject, it is likely a finite verb. Also, a finite verb will serve as the main verb of an independent clause.
Q2: Can a sentence have more than one finite verb?
A: Yes, a sentence can have multiple finite verbs if it contains multiple independent clauses connected by conjunctions or semicolons. Each independent clause requires its own finite verb.
Q3: What is the difference between a present participle and a gerund?
A: Both present participles and gerunds end in “-ing,” but they have different functions. A present participle acts as an adjective, modifying a noun, or forms part of
a continuous verb tense. A gerund, on the other hand, functions as a noun.
Q4: How do I know when to use a gerund or an infinitive after a verb?
A: Some verbs can be followed by either a gerund or an infinitive, but the meaning might change. There are no strict rules, but here are some guidelines:
- Verbs of liking or disliking (like, love, hate, enjoy) often take gerunds.
- Verbs expressing intention or decision (want, decide, plan) often take infinitives.
- Some verbs have different meanings depending on whether they are followed by a gerund or an infinitive (e.g., “remember,” “forget,” “stop”).
It’s best to learn these usages through practice and exposure to the language.
Q5: What is a bare infinitive, and when is it used?
A: A bare infinitive is an infinitive without the word “to.” It is used after modal verbs (can, could, will, would, shall, should, may, might, must) and after certain verbs like “let,” “make,” “see,” “hear,” and “help.”
Conclusion
Mastering the distinction between finite and non-finite verbs is essential for constructing grammatically correct and sophisticated sentences. Finite verbs serve as the backbone of independent clauses, providing tense and agreement, while non-finite verbs enrich sentences by functioning as nouns, adjectives, or adverbs.
By understanding the types, usage rules, and common mistakes associated with these verb forms, you can significantly improve your writing and speaking skills.
Continue to practice identifying and using finite and non-finite verbs in various contexts to solidify your understanding. With consistent effort, you’ll be able to confidently navigate the complexities of English grammar and express yourself with clarity and precision.
