A subordinate clause is a group of words, which include a finite or nonfinite verb.  The subordinate clause cannot stand independently as it is not complete as a statement, and thus remains a dependent clause. it has to join the main or independent clause to complete a sentence.

Each of the following shows a subordinate clause (in bold) that is a part of another clause, which is the main clause. Both clauses together form a complete sentence.
  • Everyone says that you are my best friend.
  • When it got hotter, all of us sat beneath a shady tree.
  • My uncle, who has a mongoose with a long body and tail, is looking for another mongoose.

 

The subordinate clause comes in different forms as follow:

  1. Adverbial Clause
  2. Noun Clause
  3. Relative Clause
  4. Nonfinite Clause
