Non-finite Clauses 

In this lesson we learn about non-finite clauses, which are essential groups of words that contain a verb form that does not show tense and do not act as the main verb in a sentence. Clear explanations and practice exercises to help you learn.

What Are Non-finite Clauses?

What Are Non-finite Clauses?

Non-finite clauses are clauses that do not have a finite verb, meaning they are not limited by tense and do not contain a subject. They are dependent clauses that do not express a complete thought and cannot function as a sentence on their own.

Non-finite Clauses: Characteristics

Non-finite clauses are dependent clauses, also known as embedded clauses, which means they cannot express a complete idea on their own. Although they look like verbs, they do not act as verbs in sentences, but as nouns, adjectives, complement, or adverbs. These clauses have no subject and do not show tense, which is why they are called non-finite. Take a look at some examples:

Example

I wanted to clean the room.

In this example, "to clean the room" does not have a complete meaning on its own.

They asked if it would be a problem to drink.

In this example, the whole sentence is in the past tense, but the clause "to drink" has no tense.

He helped take the car out of the parking lot.

The clause "take the car out of the parking lot" has no subject.

The girl crying out loud is my classmate.

A non-finite clause can act as an adjective.

Non-finite Clauses: Types

Non-finite clauses come in different types, but they are all made up of non-finite verbs. The different types of non-finite clauses include:

To-infinitives

To-infinitive clauses can serve as nouns, adjectives, complements or as adverbs of purpose, intention, or obligation in a sentence. Here are a few examples:

Example

I bought a present for you to apologize.

to-infinitive clause as an adverb

I want to make you the happiest woman ever.

to-infinitive clause as the object of the verb

The point is to solve it not to break it.

to-infinitive clause as subject complement

The book to read is on the shelf.

Bare Infinitives

A bare infinitive can be used as the object of specific prepositions as well as some verbs to indicate that someone caused or helped to do something. Here are some examples:

Example

They helped clean the house.

object of verb

I couldn't help but cry at the sight of the burning building.

object of preposition

Present Participle

A present participle clause uses the "-ing" form of the verb. Present participle clauses can act as nouns, adjectives, complements and adverbs of manner or reason. For example:

Example

They passed the hallway talking to each other.

present participle as an adverb

Drinking too much will affect your brain.

present participle as a subject

The police caught the suspect hiding in the basement.

present participle as the object complement

Past Participle

Past participle clauses use the past participle form of the verb and act as adjectives or adverbs of reason or result. Here are some examples:

Example

The man invited to the party was my uncle.

past participle as adjective

Tired after the long journey, she went straight to bed.

past participle as adverb

Perfect Participle

Perfect participle clauses use "Having" + past participle of the verb to show that an action was completed before another action. These clauses mainly function as adjectives or adverbs. For example:

Example

Having completed the task, he was free to leave.

perfect participle as an adverb

The report having been finalized yesterday is now ready for submission.

perfect participle as an adjective

Tip!

You can use non-finite clauses after catenative verbs. Here are some examples:

Example

I enjoy dancing under the rain.

I love to paint the walls.

I heard you laugh.

Restrictive or Non-restrictive Non-finite Clauses

Depending on the way non-finite clauses function in a sentence, they can be restrictive or non-restrictive. Here are a few examples:

Example

The boy sitting on the corner asks a lot of ridiculous questions. → restrictive

She rang the bell scared to death. → non-restrictive

Tip!

When a non-finite clause is used as a non-restrictive relative clause, it is typically placed between two commas. Here is an example:

Example

Harry Potter and the Chamber of Secrets, sent to me last year, was a wonderful book.
