Noun Clause and Conjunctions

♥Noun Clauses♥

See the sentence for definitions of sentence, clause, and dependent clause.

A sentence which contains just one clause is called a simple sentence.

A sentence which contains one independent clause and one or more dependent clauses is called a complex sentence. (Dependent clauses are also called subordinate clauses.)

There are three basic types of dependent clauses: adjective clauses, adverb clauses, and noun clauses. (Adjective clauses are also called relative clauses.)

This page contains information about noun clauses. Also see Adjective Clauses and 

Adverb Clause

A.  Noun clauses perform the same functions in sentences that nouns do:

A noun clause can be a subject of a verb:

What Billy did shocked his friends.

A noun clause can be an object of a verb:

Billy’s friends didn’t know that he couldn’t swim.

A noun clause can be a subject complement:

Billy’s mistake was that he refused to take lessons.

A noun clause can be an object of a preposition:

Mary is not responsible for what Billy did.

A noun clause (but not a noun) can be an adjective complement:

Everybody is sad that Billy drowned.

B.   You can combine two independent clauses by changing one to a noun clause and using it in one of the ways listed above. The choice of the noun clause marker (see below) depends on the type of clause you are changing to a noun clause:

To change a statement to a noun clause use that:

I know + Billy made a mistake =I know that Billy made a mistake.

To change a yes/no question to a noun clause, use if or whether:

George wonders + Does Fred know how to cook? =George wonders if Fred knows how to cook.

To change a wh-question to a noun clause, use the wh-word:

I don’t know + Where is George? =I don’t know where George is.

C.   The subordinators in noun clauses are called noun clause markers. Here is a list of the noun clause markers:

That,if, whether

Wh-words: how, what, when, where, which, who, whom, whose, why

Wh-ever words: however, whatever, whenever, wherever, whichever, whoever, whomever

D.  Except for that, noun clause markers cannot be omitted. Only that can be omitted, but it can be omitted only if it is not the first word in a sentence:

correct:

Billy’s friends didn’t know that he couldn’t swim.

correct:

Billy’s friends didn’t know he couldn’t swim.

correct:

Billy’s mistake was that he refused to take lessons.

correct:

Billy’s mistake was he refused to take lessons.

correct:

That Billy jumped off the pier surprised everyone.

not correct:

* Billy jumped off the pier surprised everyone.

E.  Statement word order is always used in a noun clause, even if the main clause is a question:

not correct:

* Do you know what time is it? (Question word order: is it)

correct:

Do you know what time it is? (Statement word order: it is)

not correct:

* Everybody wondered where did Billy go. (Question word order: did Billy go)

correct:

Everybody wondered where Billy went. (Statement word order: Billy went)

F.   Sequence of tenses in sentences containing noun clauses:

When the main verb (the verb in the independent clause) is present, the verb in the noun clause is:

future if its action/state is later

He thinks that the exam next week will be hard.

He thinks that the exam next week is going to be hard.

present if its action/state is at the same time

He thinks that Mary is taking the exam right now.

past if its action/state is earlier

He thinks that George took the exam yesterday.

When the main verb (the verb in the independent clause) is past, the verb in the noun clause is:

was/were going to or would + BASE if its action/state is later

He thought that the exam the following week was going to be hard.

He thought that the exam the following week would be hard.

past if its action/state is at the same time

He thought that Mary was taking the exam then.

past perfect if its action/state is earlier

He thought that George had taken the exam the day before.

If the action/state of the noun clause is still in the future (that is, after the writer has written the sentence), then a future verb can be used even if the main verb is past.

The astronaut said that people will live on other planets someday.

If the action/state of the noun clause continues in the present (that is, at the time the writer is writing the sentence) or if the noun clause expresses a general truth or fact, the simple present tense can be used even if the main verb is past.

We learned that English is not easy.

The boys knew that the sun rises in the east.

G.  Here are some examples of sentences which contain one noun clause (underlined) and one independent clause:

Noun clauses as subjects of verbs:

That George learned how to swim is a miracle.

Whether Fred can get a better job is not certain.

What Mary said confused her parents.

However you learn to spell is OK with me.

Noun clauses as objects of verbs:

We didn’t know that Billy would jump.

We didn’t know Billy would jump.

Can you tell me if Fred is here?

I don’t know where he is.

George eats whatever is on his plate.

Noun clauses as subject complements:

The truth is that Billy was not very smart.

The truth is Billy was not very smart.

The question is whether other boys will try the same thing.

The winner will be whoever runs fastest.

Noun clauses as objects of prepositions:

Billy didn’t listen to what Mary said.

He wants to learn about whatever is interesting.

Noun clauses as adjective complements:

He is happy that he is learning English.

We are all afraid that the final exam will be difficult.

♥CONJUNCTIONS♥

What is a Conjunction?

You can use a conjunction to link words, phrases, and clauses, as in the following example:

I ate the pizza and the pasta.

Call the movers when you are ready.

Co-ordinating Conjunctions

You use a co-ordinating conjunction ("and," "but," "or," "nor," "for," "so," or "yet") to join individual words, phrases, and independent clauses. Note that you can also use the conjunctions "but" and "for" as prepositions.

In the following sentences, each of the highlighted words is a co-ordinating conjunction:

Lilacs and violets are usually purple.

In this example, the co-ordinating conjunction "and" links two nouns.

This movie is particularly interesting to feminist film theorists, for the screenplay was written by Mae West.

In this example, the co-ordinating conjunction "for" is used to link two independent clauses.

Daniel's uncle claimed that he spent most of his youth dancing on rooftops and swallowing goldfish.

Here the co-ordinating conjunction "and" links two participle phrases ("dancing on rooftops" and "swallowing goldfish") which act as adverbs describing the verb "spends."

Subordinating Conjunctions

A subordinating conjunction introduces a dependent clause and indicates the nature of the relationship among the independent clause(s) and the dependent clause(s).

The most common subordinating conjunctions are "after," "although," "as," "because," "before," "how," "if," "once," "since," "than," "that," "though," "till," "until," "when," "where," "whether," and "while."

Each of the highlighted words in the following sentences is a subordinating conjunction:

After she had learned to drive, Alice felt more independent.

The subordinating conjunction "after" introduces the dependent clause "After she had learned to drive."

If the paperwork arrives on time, your cheque will be mailed on Tuesday.

Similarly, the subordinating conjunction "if" introduces the dependent clause "If the paperwork arrives on time."

Gerald had to begin his thesis over again when his computer crashed.

The subordinating conjunction "when" introduces the dependent clause "when his computer crashed."

Midwifery advocates argue that home births are safer because the mother and baby are exposed to fewer people and fewer germs.

In this sentence, the dependent clause "because the mother and baby are exposed to fewer people and fewer germs" is introduced by the subordinating conjunction "because."

Correlative Conjunctions

Correlative conjunctions always appear in pairs -- you use them to link equivalent sentence elements. The most common correlative conjunctions are "both...and," "either...or," "neither...nor,", "not only...but also," "so...as," and "whether...or." (Technically correlative conjunctions consist simply of a co-ordinating conjunction linked to an adjective or adverb.)

The highlighted words in the following sentences are correlative conjunctions:

Both my grandfather and my father worked in the steel plant.

In this sentence, the correlative conjunction "both...and" is used to link the two noun phrases that act as the compound subject of the sentence: "my grandfather" and "my father".

Bring either a Jello salad or a potato scallop.

Here the correlative conjunction "either...or" links two noun phrases: "a Jello salad" and "a potato scallop."

Corinne is trying to decide whether to go to medical school or to go to law school.

Similarly, the correlative conjunction "whether ... or" links the two infinitive phrases "to go to medical school" and "to go to law school."

The explosion destroyed not only the school but also the neighbouring pub.

In this example the correlative conjunction "not only ... but also" links the two noun phrases ("the school" and "neighbouring pub") which act as direct objects.

Note: some words which appear as conjunctions can also appear as prepositions or as adverbs.
