Basic Subordinating Conjunctions
Introduction
A subordinating conjunction is a word which joins together a dependent clause and an independent clause. This page will explain the most common subordinating conjunctions and how to use them.1. What is a dependent clause?
A clause is a unit which contains a subject and a verb. For
example, “It was raining” is a clause; the subject is “it”, and the verb
is “was raining”. A dependent clause is a clause which cannot exist on its own; it needs a main (or independent) clause to go with it. For example:
Because it was raining, I took my umbrella.
This sentence contains two clauses, “Because it was raining”
and “I took my umbrella”. The first clause does not mean anything on its
own. If you say “Because it was raining”, and nothing else, people will
not be able to understand what you mean. However, “I took my umbrella”
is an independent clause — we can understand what it means even if it is
alone.2. Joining clauses together with subordinating conjunctions
Examine the example sentence one more time:
Because it was raining, I took my umbrella.
The important word here is “because”. This is a subordinating conjunction.
It is used to show the relationship between the two clauses. A
subordinating conjunction usually comes at the beginning of the
dependent clause, but the dependent clause itself can be before the main
clause (usually followed by a comma) or after it (usually without a comma):
Although it was hot, he was wearing a coat.
He was wearing a coat although it was hot.
He was wearing a coat although it was hot.
3. Important subordinating conjunctions
Some of the most important subordinating conjunctions fall into two groups: contrast, and cause and effect.
Conjunction | Function | Example |
---|---|---|
although (even) though whereas while |
express contrast between ideas | Although she's small, she's very strong. John is short, whereas Mary is tall. |
because as since |
show a cause/effect relationship between ideas | I lost my job because I was often late. Since I have no money, I can't go to the movie. |
