Subordinating conjunctions

June 13, 2010 - pdf

A conjunction that joins together clauses of unequal rank or importance is
called a subordinating conjunction. Read the following sentence:

  • I told him that he should consult a doctor.

Here that joins together two clauses of unequal rank. I told him is the main clause, and that he should consult a doctor is a subordinate clause which is the object of the verb told in the main clause.

A subordinating conjunction connects a noun clause or an adverb clause to some other clause. Note that subordinating conjunctions are not used to connect adjective clauses.

Subordinating conjunctions introducing noun clauses

The most common subordinating conjunction used for introducing a noun clause is that; others are if, when, whether, why and how.

  • I don’t know whether he will come.
  • I think that he is trustworthy.
  • I don’t care if he comes or not.
