Key Rules & Concepts
First Conditional
The first conditional is used for real and possible situations in the future. It typically uses 'if' + present simple, followed by 'will' + base form of the verb.
Second Conditional
The second conditional is used for unreal or hypothetical situations in the present or future. It uses 'if' + past simple, followed by 'would' + base form of the verb.
Third Conditional
The third conditional is used to talk about past situations that did not happen. It uses 'if' + past perfect, followed by 'would have' + past participle.
Mixed Conditionals
Mixed conditionals combine elements from second and third conditionals to express situations where the time in the 'if' clause is different from the time in the main clause.
