Type 1 = Real / Present Conditional (terjadi sekarang)
Form = If + S + V1..., I + will + V1...
Example = If I have money, I will treat you
Meaning = it may/ may not happen. Jadi artinya bisa terjadi atau tidak.
Type 2 = Contrary to the present fact (bertentangan sama yang terjadi pada kenyataan)
Form = If + S + V2..., I + would + V1...
a. If I had money, I would treat you
b. If I were you, I would leave him
a1. I don't have money, so I dont treat you, or
a2. I don't treat you, because I don't have money
b. I'm not you, so I don't leave him
(intinya kalau conditional 2, penyataan dalam v2, arti dalam v1)
Form = If + S + had + V3..., I + would + have + V3...
a. If I had had money, I would have treated you
b. If my father had got marred again, my mother would have killed him
a. I didn't have money, so I didn't treat you
b. My father didn't get married again, so my mother didn't kill him
(intinya kalau conditional 3, penyataan dalam v3, arti dalam v2)
