CONDITIONAL SENTENCES

Conditional sentences are

complex sentences that have two

clauses: If-clause (which gives the

condition) and main clause (which

gives the result).

Conditional sentences or Conditional clauses or IF-Clauses are used to express that the action in the main clause can only take place if a certain condition is fulfilled.
