Clauses and its Types

A clause is the smallest grammatical unit that expresses a thought and consists of a subject and a verb .

What is a Clause in a Sentence?

  • In simplest form a clause is a subject plus a verb.
  • The subject is the entity “doing” the action of the sentence .
  • The verb is the action that subject completes.
  • A clause creates a complete thought (an idea or a statement that can stand alone).
A complete thought is also called a Main Clause or Independent Clause (IC).
Examples of clauses:
  • Subject + verb. = complete thought (IC)
  • I eat. = complete thought (IC)
  • Sanjay speaks. = complete thought (IC)
A clause may include the verb predicate as well. But, it must include at least the subject and verb to be considered a clause.
 
Examples of clauses:
  • Subject + verb (predicate). = complete thought (IC)
  • I eat bananas. = complete thought (IC)
  • Sanjay speaks polietly. = complete thought (IC)
It should be noted, too, that a clause in a sentence is different from a phrase in that it must contain a subject and a verb.

What is an Independent Clause?

  • An Independent clause can stand alone in a sentence.
  • It contains a subject and a verb in its smallest form.
  • A clause may also include modifiers and a verb predicate.
  • It is a complete thought and the smallest unit of grammar that is syntactically accurate.
Example of Independent Clauses:
  • Subject + verb (predicate). = complete thought (IC)
  • I eat bananas. = complete thought (IC)
  • Sanjay speaks polietly.= complete thought (IC)
In writing, words and modifiers can be rearranged in independent clauses to create interest.
 
Example of Independent Clauses:
  • I eat bananas in the kitchen.
  • In the kitchen, I eat.
Here, “I eat” is the subject and verb. An object (“bananas”) and a prepositional phrase (“in the kitchen”) have been added to the clause to make it more specific. The entire sentence is an independent clause because it is a complete thought statement.

What is a Dependent Clauses?

Dependent clauses contain a subject and verb. However, they cannot stand alone as an independent thought. They must be joined with an independent clause to be grammatically correct.
 
Example of Dependent Clause:
  • Every night before I go to bed, I pray to God.
This example contains the IC, “ I pray to God”. However, a dependent clause now opens the sentence. While the dependent clause contains a subject and a verb (“I go”), the dependent clause itself cannot stand alone a complete thought.
 
Example of Dependent Clause:
  • Every night before I go to bed
This is not a complete thought and therefore not a sentence in English.
 
Every night before I go to bed…...What happens?
 
This idea must be joined with an independent clause to be grammatically correct.

More Types of Clauses

What is a Noun Clause?
  • A Noun clause is a type of dependent clause that acts as a noun in the sentence.
  • A noun clause will always contain a subject and a verb. However, it cannot stand alone as a complete thought.
Example of Noun Clause:
  • I remember what you said yesterday.
Here, the underlined portion is the independent clause that can stand alone. The italicized words, “what you said yesterday,” serve as a dependent noun clause.
 
The noun clause is acting as the object of the sentence. In the noun clause “you said” is a subject plus a verb. This creates the clause (a subject plus a verb). However, “what you said yesterday” cannot stand alone and therefore must be paired with an independent clause.
 
Additional noun clause examples:
  • I thought what she wore was so trendy.
  • Whomever you confide in is a person you can trust.
What is an Adjective Clause? (Also called Relative Clause)
  • An Adjective clause is a type of dependent clause that acts as an adjective in the sentence.
  • An adjective clause will always contain a subject and a verb. However, it cannot stand alone as a complete thought.
An adjective clause will always begin with one of the following words:
Relative Pronouns List:
  • that
  • where
  • who
  • whom
  • which
Relative Adverbs List:
  • when
  • where
  • why
Example of Adjective Clause:
  • The boy who you saw at the store committed a robbery.
The adjective clause is acting as an adjective in this sentence. The adjective clause describes the boy. It contains a subject and a verb, “you saw.” However, it cannot stand alone as a complete thought. “Who you saw at the robbery” is not a complete statement.
Additional adjective clause examples:
  • The store that the boy robbed is on the corner.
  • The corner of the street where my family lives is surrounded by investigators.
What is an Adverbial Clause?
  • An Adverbial Clause is a type of dependent clause that acts as an adverb in the sentence.
  • An adverbial clause will always contain a subject and a verb. However, it cannot stand alone as a complete thought.
Example of Adverbial Clause:
  • You will continue driving north until you see a stop sign.
The adverbial clause is acting as an adverb in this sentence.The adverbial clause modifies how you will drive. The adverbial clause contains a subject and verb, “you will continue.” However, it cannot stand alone as a complete thought. “Until you see a stop sign” is not a complete statement.
 
Additional adverbial clause examples:
  • After the movie ended, we ate ice cream.
  • Beth visits her grandfather whenever she is in town.
Summary: What are Clauses in Grammar?
  • A clause is a subject plus a verb.
  • Two types of clauses are main/independent clause and dependent clause.
  • An independent clause can stand alone as a complete thought.
  • A dependent clause contains a subject and a verb but cannot stand alone.
