3. Third conditional:

Conditional clauseMain clause
1. If + Present Tense will + inf / present tense / imperative


  • If you help me with the dishes (if + pres),
    I will help you with your homework. (will + inf)
  • If the sum of the digits of a number is divisible by three,
    the number is divisible by three (Pres. tense)
  • If you see Mr Fox tonight, tell him I am ill. (imperative).
  • 2. If + Past Tense would + inf
    3. If + Past Perfect Tense would have + past participle
    We do not normally use will or would in the conditional clause,
    only in the main clause.



    Uses of the Conditional




    1. First conditional

      1. Nature: Open condition, what is said in the condition is possible.
      2. Time: This condition refers either to present or to future time.

        e.g. If he is late, we will have to go without him.

        If my mother knows about this, we are in serious trouble.



    2. Second conditional

      1. Nature: unreal (impossible) or improbable situations.
      2. Time: present; the TENSE is past, but we are talking about the present, now.

        e.g. If I knew her name, I would tell you.

        If I were you, I would tell my father.

        Compare: If I become president, I will change the social security system. (Said by a presidential candidate)

        If I became president, I would change the social security system. (Said by a schoolboy: improbable)

        If we win this match, we are qualified for the semifinals.

        If I won a million pounds, I would stop teaching. (improbable)



    3. Third conditional

      1. Nature: unreal
      2. Time: Past (so we are talking about a situation that was not so in the past.)

        e.g. If you had warned me, I would not have told your father about that party.(But you didn't, and I have).
