CLAUSE AND ITS TYPES
Clause
“A clause is a group of related words containing a subject and a predicate”
For example, he laughed.
A clause refers to a group of related words (within a sentence or itself as an independent sentence) which has both subject and predicate.
Example
I will meet him in office.
The part of above sentence “I will meet him” is a clause because it has a subject(I) and a predicate(will meet him). On the other hand, the rest part of above sentence “in office” lacks both subject and predicate(verb) such group of word is called phrase.
A clause may stand as a simple sentence or may join another clause to make a sentence. Therefore, a sentence consists of one, two or more clauses.
Examples.
• He is sleeping. (one clause)
• The kids were laughing at the joker. (one clause)
• The teacher asked a question, but no one answered. (two clauses)
• I am happy, because I won a prize. (two clauses)
• I like Mathematics, but my brother likes Biology,
because he wants to become a doctor. (three clauses)
Clauses are divided into main clause (also called independent clause) and subordinate clause (also called dependent clause).
Types of Clauses
There are two major types of clauses: main (or independent) clause and subordinate (or dependent) clause.
Main Clause and Subordinate Clause – Comparison
He is buying a shirt which looks very nice.
The above sentence has two clauses “He is buying a shirt” and “which looks very nice”. The clause “He is buying a shirt” expresses a complete thought and can alone stand as a sentence. Such a clause is called the main or independent clause.
While the clause “which looks very nice” does not express a complete thought and can’t stand as a sentence. It depends on another clause (main clause) to express a complete idea. Such a clause is called a subordinate or dependent clause.
Main or Independent Clause
“Main (or independent) clause is a clause that expresses a complete thought and can stand as a sentence.
Examples
I met the boy who had helped me.
She is wearing a shirt which looks nice.
The teacher asked a question but no one answered.
He takes medicine because he suffers from fever.
He became angry and smashed the vase into pieces.
In the above sentences each underlined part shows the main clause. It expresses complete thought and can stand as a sentence that is why a main or an independent clause is normally referred to as a simple sentence.
Subordinate or dependent Clause
A subordinate (or independent) clause is a clause which does not express complete thought and depends on another clause (main clause) to express complete thought. The subordinate clause does not express the complete idea and can’t stand as a sentence. A sentence having a subordinate clause must have a main clause.
Example
He likes Chinese rice which tastes good.
The clause “which tastes good” in the above sentence is a subordinate clause because it does not express complete thought and can’t stand as a sentence. It depends on the main clause (he likes Chinese rise) to express complete thought.
Examples.
I met the boy who had helped me.
I bought a table that costs $ 100.
He takes medicine because he suffers from fever.
The teacher asked a question but no one answered.
Subordinate (or dependent) clauses are further divided into tree types,
1. Noun Phrase, 2. Adjective Phrase, 3. Adverb Phrase
Types of Subordinate Clause
Functions of Subordinate Clause.
A subordinate (dependent) clause may function as a noun, an adjective or an adverb in a sentence. On the basis of their function in a sentence, subordinate clauses can be divided into following types.
1. Noun Clause
2. Adjective Clause.
3. Adverb Clause
Noun Clause
“A dependent clause that functions as a noun in a sentence is called a noun clause.”
A noun clause performs the same function like a noun in a sentence.
Example
What he did made a problem for his family.
In the above sentence the clause “what he did” functions as a noun, hence it is a noun clause. A noun clause works as a noun that acts as a subject, object, or predicate in a sentence. A noun clause starts with words “that, what, whatever, who, whom, whoever, whomever”.
Examples
Whatever you learn will help you in future. (noun clause as a subject)
What you said made me laugh. (noun clause as a subject)
He knows that he will pass the test. (noun clause as an object)
Now I realize what he would have thought. (noun clause as an object)
Adjective Clause
“A dependent clause that functions as an adjective in a sentence is called an adjective clause.”
An adjective clause works like an adjective in a sentence. The function of an adjective is to modify (describe) a noun or a pronoun. Similarly a noun clause modifies a noun or a pronoun.
Example
He wears a shirt which looks nice.
The clause “which looks nice” in the above sentence is an adjective clause because it modifies the noun “shirt” in the sentence.
An adjective clause always precedes the noun it modifies.
Examples.
I met the boy who had helped me.
An apple that smells bad is rotten.
The book which I like is helpful in preparation for tests.
The house where I live consists of four rooms.
The person who was shouting needed help.
The adjective clause begins with a relative pronoun (that, who, whom, whose, which, or whose) and is also a relative clause.
Adjective (relative) clauses can be restrictive clause or nonrestrictive clause
Restrictive and Nonrestrictive Clauses
Adjective (relative) clauses can be restrictive clauses or nonrestrictive clauses. A restrictive clause limits the meaning of preceding noun or pronoun. A nonrestrictive clause tells us something about preceding noun or pronoun but does not limit the meaning of preceding noun or pronoun.
Example
•The student in the class who studied a lot passed the test. (restrictive clause)
•The student in the class, who had attended all the lectures, passed the test. (nonrestrictive clause)
In the first sentence the clause “who studied a lot” restricts information to preceding nouns(student), it means that there is only one student in the class who studied a lot, hence it is a restrictive clause.
In the second sentence the clause “who had attended all the lectures” gives us information about preceding nouns but does not limit this information to the preceding noun. It means there can be several other students in the class who have attended all the lectures.
A comma is always used before a restrictive clause in a sentence and also after a nonrestrictive clause if it is within a main clause. “That” is usually used to introduce a restrictive clause while “which” is used to introduce a nonrestrictive clause.
Example
The table that costs $ 100 is made of steel. (restrictive clause)
The table, which costs $ 100, is made of steel. (nonrestrictive clause)
Adverb Clause
“A dependent clause that functions as an adverb in a sentence is called adverb clause”
An adverb clause like an adverb modifies a verb, adjective clause or other adverb clause in a sentence. It modifies(describes) the situation in the main clause in terms of “time, frequency (how often), cause and effect, contrast, condition, intensity (to what extent).”
The subordinating conjunctions used for adverb clauses are as follows.
Time: when, whenever, since, until, before, after, while, as, by the time, as soon as
Cause and effect: because, since, now that, as long as, so, so that,
Contrast: although, even, whereas, while, though
Condition: if, unless, only if, whether or not, even if, providing or provided that, in case
Examples.
Don’t go before he comes.
He takes medicine because he is ill.
Although he tried a lot, he couldn’t climb up the tree.
Unless you study for the test, you can’t pass it.
I will go to school unless it rains.
You are safe as long as you drive carefully.
You can achieve anything provided that you struggle for it.
