CONDITIONAL SENTENCES

CONDITIONAL SENTENCES

Conditional sentences are also known as conditional clauses or if clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition ( in the clause with if ) is fulfilled. There are three types of conditional sentences.

Verb form in “IF CLAUSE”	Verb from in “ RESULT CLAUSE “	Meaning
I.                   Present tense	Future tense	Real in present/future
( IF + S + V1 , S + WILL + INFINITIVE)
II.                Past tense	Past future	Unreal in present/future
(IF + S + V2, S + WOULD + INFINITIVE)
III.             Past Perfect	Past future perfect	Unreal in past
(IF + S + HAD + V3 , S + WOULD HAVE + V3 )
