Grammar: Word classes: Conjunctions

Overview

What is a conjunction?

Conjunctions are words that are mainly used to connect one clause to another:

Bozo throws a stick  // and Barney runs to get it.
clause 1                                clause 2

When Bozo throws his stick, // Barney runs to fetch it.
clause 1                                                 clause 2

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

type conjunctions
coordinating conjunctions and, or, but, yet, then, so, nor, either, neither
subordinating conjunctions because, if, when, while, before, after, until, although, unless, since, whether, (in order) to, so (that)

Coordinating conjunctions connect independent clauses:

Bozo throws a stick  // and Barney runs to get it.
independent clause              independent clause

Subordinating conjunctions connect independent clauses to dependent clauses:

When Bozo throws his stick, // Barney runs to fetch it.
dependent clause                                  independent clause

Bozo throws his stick  // because Barney loves to fetch it.
independent clause                  dependent clause

Connecting text to text

Some conjunctions, especially and, but, then, so and because, may also be used to create cohesion Glossary by making connections between stretches of text:

MegaMonster swallowed so much water that he became enormous. His body rose above the water in the harbour. "There’s the water thief!" the children shouted. "Give us our water back!"

But MegaMonster just smiled. ...

When conjunctions are used in this way, they often signal a new 'stage' in the text.

In summary, conjunctions connect one language item to another. These language items can be of various kinds:
