sentences contain two clauses:
the condition clause (if clause)

Conditional sentences show a
relationship between a condition
and a result of the condition

The if clause is in the present and the result
clause is in the future with will or be going to.

will happen in the future if certain
conditions occur. They are often
used to make predictions, plans,
offers, suggestions, requests.

result of an imagined condition.

not true in the past

imagined condition in the past
Past unreal conditionals have a
past perfect form of verb in the If
would/could/might + have + past
of the verb in the result clause

conditional expresses a condition
that was not true in the past.
