Type 3 conditional (Impossible condition)

Here we use a past perfect tense in the if clause and would have + past participle in the result clause.

A conditional sentence must have at least two clauses: a conditional clause and a result clause. The conditional clause usually states a condition and the result clause states what will happen if the condition is fulfilled.

Frequency adverbs tell how often something happens. Examples are: often, never, always, sometimes, generally, usually, seldom, rarely, hardly, ever, frequently etc.
