French if then clauses

The third conditional is an if-then proposition that expresses an impossible situation:

If something had happened (the condition), then something else would have happened (the result).

The condition is expressed with the past perfect, and the impossible result is indicated with the conditional perfect.

 The order of the clauses makes no difference as long as si / "if" stays in front of the correct verb form:

  • Si + past perfect + conditional perfect
  • Conditional perfect + si + past perfect
