What are Clauses: Definition, Types, Examples, & Exercise

Clauses are amongst the basic topics of English grammar that continue to reign in the syllabus at the secondary school level. You might remember studying Sentences, Phrases, and Clauses in your English grammar book and their intricacies.

During the school years, the formation of sentences is the very first and basic step towards learning English grammar before we get into the complexities of parts of speech, conjunctions, and punctuation. This blog brings you a comprehensive guide on what this grammatical tool is, as well as its key types and examples. 

What are Clauses? Definition and Example

It is mainly a group of words that contain a subject as well as a finite verb. A sentence can be fully called a clause only when it has a single subject and a single verb. It might not include the subject at times, but the verb has to be clear and distinguished.

In simple words, a clause is a group of words that contains both a subject (who or what the sentence is about) and a predicate (what the subject does). Clauses may stand alone as complete sentences or may depend on another part of the sentence for meaning.

Clauses Examples:

1. I completed my graduation last year.
2. When he came here, he ate apples.
3. When I came here, he was playing, and then he went back home.

Types of Clauses

As discussed, every clause has a subject and a verb, but some other characteristics can help you distinguish its types. To begin with, there are six types of clauses as mentioned below:

1. Independent or Main
2. Dependent or Subordinate
3. Relative or Adjective
4. Noun Clause
5. Adverbial Clause
6. Conditional Clause

We will be discussing each of the types separately, along with their examples, in the following section.

1. Independent or Main Clause

It is a complete sentence on its own and does not require anything else to make it a full-fledged sentence. Its basic form is:

Subject + Verb = Complete Sentence

Let us consider some examples to understand it better:

1. These boys are always sleeping. (The subject is ‘boys’, whereas the verb is ‘sleeping’.)
2. My sister loves cold drinks. (The subject is ‘sister’ and the verb is ‘loves’.)
3. I read the book. (The ‘I’ represents the subject, whereas the verb is ‘read’.)

2. Dependent or Subordinate Clause

A dependent/subordinate clause is the exact opposite of an independent clause. It is not a complete sentence and thus generally does not make any sense. But when put together with an independent one, it helps it to form a complete sentence.

The task of joining a dependent clause to an independent clause or any other of its type is done by a subordinator, which makes the sentence complete. A subordinator might be a conjunction, a relative pronoun or a noun clause marker.

Subordinator + Subject + Verb = Incomplete Sentence

Now, let us take a look at some examples:

1. Whenever the boys sleep. (‘Whenever’ is the subordinator, ‘boys’ corresponds to the subject and ‘sleep’ is the verb.)
2. Because my sister loves cold drinks. (‘Because’ is the subordinating conjunction, ‘sister’ represents the subject and ‘loves’ is the verb)
3. If you don’t go (‘if’ is the subordinator, ‘you’ represents the subject and ‘go’ is the verb)

Thus, through the above examples, you can see how it is quite difficult for a dependent type alone to make any sense. It has to be joined to an independent one by a punctuation mark to make complete sense. Hence, the form of a complete sentence stands to be:

Subordinate Clause + Punctuation + Main Clause = Complete Sentence

OR

Main Clause + Subordinate Clause = Complete Sentence

Examples:

1. Whenever the boys sleep, their teacher scolds them.
2. I bought two bottles of cola because my sister loves cold drinks.
3. If you don’t go, I will get angry.

3. Relative Clause

A relative clause will always begin with either a relative pronoun such as ‘who’, ‘whom’, ‘whose’, ‘which’, ‘that’ or a relative adverb such as ‘when’, ‘why’ or ‘where’. You must also remember that a relative alone does not make any sense or a complete sentence; it also has to be attached to a main clause, just like a dependent one.

Relative Pronoun /Adverb + Subject + Verb = Incomplete Sentence

OR

Relative Pronoun or Adverb as subject + Verb = Incomplete Sentence

Examples:

1. Whom the teacher hit with chalk (‘whom’ is the relative pronoun, ‘teacher’ is the subject and ‘hit’ is the verb )
2. Where he went joyfully (‘where’ is the relative pronoun, ‘he’ is the subject and ‘went’ is the verb)

Relative + Main Clause = Complete Sentence

Examples:

1. The talkative boys whom the teacher hit with chalk soon learned to behave properly in class.
2. I know about the place where he went joyfully.

Restrictive Relative Clause

A restrictive clause gives essential information about a noun that comes before it. A restrictive clause can be introduced by that, which, whose, who or whom. You should not place a comma in front of a restrictive relative clause: 

For example: 

1. She held out the hand that was hurt.
2. She held out the hand which was hurt. 

(She held out the hand = Main Clause)

( That was hurt, which was hurt = Restrictive Relative Clause)

Non-Restrictive Relative Clause

These clauses are normally introduced by which, whom, who or whose, but never by that. You should place a comma in front of them:

For Instance: 

1. She held out her hand, which Rob shook. 
   (She held out her hand = Main Clause
   (which Rob shook = Non-Restrictive Clause)

4. Noun Clause

When a sentence starts functioning as a noun, it is known as a noun clause. Take a look at the following example,

Let me know the ingredients of the stew. (‘Ingredients’ is the noun.)
When this noun is replaced with a clause, it becomes a noun clause.
Let me know all that you have added to the stew.

5. Adverbial Clause

An adverbial clause is a group of words that plays the role of an adverb. 

For example:

1. He lost his double chin after he gave up chocolate 
   (The clause acts as an adverb. It could be replaced with an adverb, eg: Recently) 

2. I am not afraid of the pen, the scaffold, or the sword. I will tell the truth where I please. 
   (This clause could be replaced with an adverb, eg, There) 

6. Conditional Clause

A condition clause is one that usually begins with if or unless and describes something possible. 

For Instance: 

1. If it looks like rain, a simple shelter can be made out of a plastic sheet. 
   (If it looks like rain = Conditional)
   (A simple shelter can be made out of a plastic sheet = Main)
2. I’ll be home tomorrow unless the plane’s delayed for hours.
   (I’ll be home tomorrow = Main)
   (unless the plane’s delayed for hours = Conditional)

Rules for Using Clauses

The rules for using clauses guide how to combine independent and dependent clauses correctly. Following these rules ensures clarity, proper sentence structure, and effective communication in writing and speech. Here are some of the rules for using clauses: 

• Every clause must contain at least a subject and a verb.
• Independent clauses can form complete sentences; dependent clauses cannot.
• Dependent clauses must be attached to an independent clause for clarity.
• Punctuation is important when combining clauses (for example, using commas with subordinating or coordinating conjunctions).

Examples of Clauses and Phrases

Both are groups of words that act as a unit and perform a single function within a sentence. A phrase is a group of words that may have a partial subject or verb but not both, or it may have either a subject or a verb. A clause, however, by definition, is a group of words that has a subject and a verb. A sentence can have any number of clauses and phrases combined. See the examples below: 

Phrases	Clauses
Needing help	Sarah smiled
With a green T-shirt	She laughs at shy people
Best friend	Because he gave her a puppy
On the horizon	When the saints go marching in
After the devastation	I waited for him
Because of her glittering smile	He wants to become an engineer
