They can join together words, parts of sentences and even whole sentences. They help to make writing flow.

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, such as subordinate clauses, cannot be a complete sentence on their own.

when the rocket launched

The subordinate clause 'when the rocket launched' includes the subordinating conjunction 'when'.

It needs to be linked to a main clause to make a complete sentence.

The ground shook when the rocket launched.

What are the types of conjunctions?

There are two types of conjunctions, coordinating conjunctions and subordinating conjunctions.

Coordinating conjunctions

Coordinating conjunctions link main clauses together.

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

There are only seven co-ordinating conjunctions.

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

Subordinating conjunctions

Subordinating conjunctions link subordinate clauses to main clauses.

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

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

There are many subordinating conjunctions, but some common ones include:

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

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

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