Simple, Compound and Complex Sentences – A Short Recap

Before you start working on the exercises, take a few minutes to look at how each type of sentence is formed and used. A simple sentence is a short sentence consisting of a subject and a predicate. In other words, it can be said that a simple sentence is one main clause. It can also be a combination of a phrase and a clause.

A compound sentence is a sentence that has more than one main clause. It should have at least two main clauses and they can be combined using a coordinating conjunction or a conjunctive adverb; whereas, a complex sentence should have a main clause and a subordinate clause. The two clauses can be combined using a subordinating conjunction or a correlative conjunction.

Now, try out the following exercises to check your understanding.
