Simple Sentences

To create exciting writing, we need to use different types of sentences. A simple sentence is a sentence that has only 1 clause. Here are some simple sentences...

  • This is a simple sentence because it only contains a subject ('the dog'), a verb ('ate') and an object ('the treat').
The boy read the book.

The boy read the book.

  • This is a simple sentence because it only contains a subject ('the boy'), a verb ('read') and an object ('the book').
The frog wore a crown.

  • This is a simple sentence because it only contains a subject ('the frog'), a verb ('wore') and an object ('a crown').
The horses galloped.

The horses galloped.

  • This is a simple sentence because it only contains a subject ('the horses') and a verb ('galloped').
  • Sometimes, a simple sentence doesn't even have an object.

  • This is a simple sentence because it only contains a subject ('my mother'), a verb ('bought') and an object ('an ice cream').
The cake had candles.

  • This is a simple sentence because it only contains a subject ('the cake'), a verb ('had') and an object ('candles').

Compound Sentences
