How to use conjunctions

Conjunctions link clauses together. A clause is a group of words with a verb.

A girl dressed as an astronaut with question marks surrounding her.

A main clause can stand alone as a sentence.

The ground shook.

Other clauses cannot be a complete sentence on their own.

when the rocket launched

The clause 'when the rocket launched’ includes the conjunction ‘when’.

However, it does not make sense as a complete sentence by itself because it leaves the reader waiting for more information about what happened when the rocket launched.

The ground shook when the rocket launched.

What are the different ways to use conjunctions?

Conjunctions link main clauses together.

I want to go to space. I need a rocket.

Becomes:

I want to go to space but I need a rocket.

The conjunction 'but' has been used like a bridge to link the two clauses together.

Examples of conjunctions you can use to link main clauses are:

for, and, nor, but, or, yet, so

Conjunctions can also link parts of a sentence that don’t make sense on their own to a main clause.

Maya started to feel nervous.The engine roared to life.

Becomes:

Maya started to feel nervous as the engine roared to life.

The conjunction 'as' has been used to link the main clause 'Maya started to feel nervous' to 'as the engine roared to life'.

There are many conjunctions you can use to link parts of a sentence that don't make sense on their own.

Some common ones include:

when, as, if, because, although, while, before, after

These conjunctions can also appear at the start of a sentence.

As the engine roared to life, Maya started to feel nervous.
