CBSE Class 11 English Grammar – Tenses (Tenses in Conditional Sentences)

A conditional sentence has two parts—the main clause and the conditional clause (if—clause). There are three types of conditions:
Type I : Possible — relating to future.
Type II : Probable or Hypothetical —unfulfilled condition of the Present.
Type III : Impossible or Imaginary — unfulfilled condition of the Past.
The tenses of verbs in the two clauses follow this pattern.
