Clauses of conditions (also called conditional clauses) follow conjunctions si (if), même si (even if), à moins que (unless), au cas où (in case that), à condition que (on condition that), pourvu que (provided that), vu que (given that):
Même si j'avais su
que vous donniez une fête, je ne serais pas venue.
(Even if I had known that you were giving a party, I would not
have come.)
The tense in the subordinate clause may vary based on the tense used in the main clause.
