Simple, compound and complex sentences
There are three types of sentence:
- simple
- compound
- complex
All of them have an equally important role in writing.
Watch: Writing in sentences
What are simple sentences?
Simple sentences have a subject (鈥榳hat鈥 or 鈥榳ho鈥) and just one main verb (a 鈥榙oing鈥 word).
For example:
鈥楬别 walked quickly back to the house.鈥
Simple sentences are important for making clear points.
Be careful though - if you only ever use simple sentences in your writing you don鈥檛 add much detail, so your reader could lose interest.
What are compound sentences?
Compound sentences have more than one verb and contain two or more clauses.
The clauses in a compound sentence still make sense on their own and so we use coordinating conjunctions, such as 'and', 'but' and 'so' to link them together.
For example:
George realised he had forgotten his wallet so he walked quickly back to the house.
Both clauses on each side of 'so' make sense on their own.
Compound sentences are useful for connecting events and ideas in your writing.

What are complex sentences?
Complex sentences include a subordinate clause.
Go back to the video you have just watched and listen from 0:47 to the end.
Subordinate clauses are sometimes known as 'dependent clauses' because they need the main part of the sentence to make sense. They don鈥檛 make complete sense on their own.
For example:
George wanted to stay outside despite the driving rain and wind.
The subordinate clause here (鈥榙espite the driving rain and wind鈥) does not make sense on its own.
We use subordinate clauses to add extra information to the main clause.
Using complex sentences is an effective way to add more detail and interest to your writing, which is great for your reader!
Activity 1
You are going to create your own superhero!
First, draw your superhero on a piece of paper.
Around your drawing you need to write:
- Your superhero鈥檚 name.
- The special things they鈥檙e able to do - their 鈥榮uperpowers鈥.
- Words and phrases to describe them.
Try to picture your superhero in your mind and think about how they might behave or move around, to help you think of good ways to describe them.
Activity 2
Next, underneath the drawing of your superhero, or on a new piece of paper, write at least four simple sentences about your superhero.
For example:
Super Dog runs quickly.
Remember, a simple sentence has one main verb and makes sense on its own.
Think carefully about the following when you are writing sentences:
Is your sentence a statement, a question or an exclamation?
Have you remembered to use correct punctuation?
Activity 3
Now, say even more about your superhero by writing sentences that contain more detail.
Try to write at least three compound sentences about your superhero.
Remember, a compound sentence joins two main clauses together. Use words like 'and', 'so' or 'but' to your sentence to make it compound.
For example:
Super Dog鈥檚 sidekick is called Punchy Puppy and together they fight crime.
Activity 4
Go further - now try writing at least two complex sentences about your superhero.
Remember, a complex sentence uses a subordinate clause to add extra detail. Use words like 'because', 'when' or 'despite' to make the sentence complex.
For example:
Super Dog鈥檚 arch enemy is Bad Cat because he wants to get rid of all dogs!
Activity 5
Turn each pair of simple sentences below into one compound sentence by using one of these words:
- and
- but
- so

- Poppy sat on the beach. She ate a big ice cream.
