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.
