What is the Conditional Mood?
The conditional mood is used in hypothetical situations; situations in which the result depends on whether a situation happens or not.
Conditional sentences connect real or unreal situations to possible or impossible results.
The conditional mood can express:
-
what actually happens
-
what will happen
-
what could happen
-
what might have happened
-
what we wish would have happened
Conditional Clauses
Conditional sentences contain two clauses:
Conditional clause (commonly called the if-clause): the condition/situation
Main clause: the result
The if-clause is a dependent clause. To form a complete sentence, it needs the hypothetical result.
The condition If she had her guitar, does not form a complete sentence. It needs the result, she would play a song to be a complete sentence.
Clauses can be moved around in a sentence without changing the meaning.
In writing, there is a minor difference:
When the if-clause (condition) comes first, a comma follows it to separate it from the main clause (result).
If the main clause (result) comes first, punctuation isn’t necessary.
