Complex Sentences

Complex Sentences

A complex sentence is made up of two clauses: a main clause and a subordinate clause.


A main clause makes sense on its own. 

  • It is a simple sentence. 
  • It is independent. 

A subordinate clause does not make sense on its own. 

  • It is dependent on the main clause. 


To help us remember the subordinating conjunctions we can use I SAW A WABUB (see below). 


Points to remember:

  • If the subordinate clause comes first, you need a comma to separate the two clauses. 
  • If the subordinate clause is at the end of the sentence, you do not need a comma.
