"Noun Clauses" in the English Grammar

What Is a Noun Clause?

A noun clause (also called a nominal clause) is a clause that acts as a noun. These clauses are always dependent clauses. That is, they do not form a complete sentence.

Noun Clause: Structure

Like all clauses, a noun clause has a subject and a verb. Consider these examples:

They know Carlos Mattel.

In this example, the object of the sentence is a noun.

They know that greenhouse gases can affect the climate.

In this example, the object of the sentence is a noun clause.

Tip!

Typically a noun clause starts with: a 'wh-word' (what, who, which, when, where, why, how) or 'that.' For example:

  1. Relative pronouns: that, which, who, whom, whose, what
  2. Indefinite relative pronouns: whoever, whomever, whatever, whichever
  3. Interrogatives: who (interrogative pronoun), what (interrogative adjective), how (interrogative adverb)
  4. Subordinating conjunctions: how, if, whether, when, why

I saw that it happened.

I saw how it happened.

I saw why it happened.

Noun Clauses: How to Identify

If you want to know whether a phrase or clause is functioning as a noun or not, try replacing it with a pronoun. If it makes sense, your phrase or clause is acting as a noun.

What you did is important. → It is important.

By replacing 'what you did' with a pronoun you can see that 'What you did' is functioning as a noun.

Teach me how to make these cakes. → Teach me them.

By replacing 'how to make these cakes' with a pronoun you can see that 'how to make these cakes' is functioning as a noun.

Noun Clause: Uses

Noun Clauses: As Subjects

Subjects in grammar are words, phrases, or clauses that do the action of or act upon verbs. They can be nouns, pronouns, and noun clauses. Take a look at the following examples:

Why she ever dated such an idiot in the first place is beyond me.

In this example, the noun clause acts as the subject of the independent clause.

Whoever is responsible for this mess will be punished.

What you said yesterday really hurt me.

Noun Clauses: As Direct Objects

Using a Noun Clause as the Object

Noun clauses can function as direct objects of the verb in the sentence (the independent clause).
Direct objects are words, phrases, or clauses that receive the action of a transitive verb. Sometimes a noun clause can function as the direct object. Examples of noun clauses as direct objects include the following:

He finally confessed that he had been having an affair with a women from the neighborhood.

You can choose what you want to do next.

Noun Clauses: As Indirect Objects

Noun clauses can also function as indirect objects of the verb in the sentence (the independent clause).
Indirect objects are words, phrases, or clauses that receive the action of a ditransitive verb. Sometimes a noun clause can function as the indirect object. Take a look at some examples of noun clauses as indirect objects:

I should have given what my friends said about moving out of my parents house sooner some thought and consideration.

She will tell whoever will listen her terrifying story.

Noun Clauses: As Objects of the Prepositions

Other times, noun clauses can act as the object of a preposition in the independent clause. For example:

I like to keep a schedule of when I have upcoming appointments.

In the sentence above, the noun clause 'when I have upcoming appointments' is acting as the object of the preposition 'of.'

My teacher is writing a book about how people can improve their social skills.

Noun Clauses: As Subject Complements

Noun clauses can act as subject complements, or nouns that follow linking verbs. In addition to nouns and pronouns, noun clauses also perform the grammatical function of subject complement. Noun clauses that function as subject complements are also referred to as predicate nominatives and predicate nouns.

You can become whomever you want to be in life.

In the sentence above, the noun clause whomever they want to be is the subject complement of the linking verb become.

The problem is that street crime is getting worse every year.

Noun Clauses: As Appositives

Appositives are words, phrases, or clauses that describe or modify another word, phrase, or clause. Typically nouns and noun phrases have this rule, but noun clauses also perform this grammatical function.

The problem, that street crime is getting worse every year, worries the whole community.

The answer from her husband, that they should get a divorce, devastates her.

Clauses: Nominal or Adverbial?

Identifying the types of dependent clauses from each other can be somehow confusing. One way to identify if a clause is adverbial or nominal is to ask these questions about the clause:

  • Ask If the clause answers the questions, 'who?' or 'what?,' then it is a noun clause.
  • If the clause answers the questions: 'where?,' 'how?,' 'when?,' or 'why?,' then it is an adverbial clause.

Noun Clause (acting as a subject): When Mary comes depends on her time of the flight.

Adverbial Clause (acting as an adverb): When Mary comes, we will start the party.

Tip!

The main difference between noun clauses and relative or adverbial clauses is that relative clauses and adverbial clauses modify nouns and verbs respectively, noun clauses replace nouns altogether.

Review

'Noun clauses' are dependant clauses that do not form a meaningful sentence. They sit instead of a noun. These noun clauses can function as:

  • Appositives
  • Subject complements
  • Objects of the preposition
  • Indirect object
  • Direct object
