CONDITIONAL SENTENCE TYPE 3
IF CLAUSES / CONDITIONAL CLAUSES (Type 3)
Conditional clauses consist of two sentences. One is a clause that starts with if, which is called as ‘if clause’. The other is called the Main clause. Each sentence has a verb. It is important to know which tenses are to be used in these clauses and they play a big role in determining the meaning of the sentence. Detailed information for the type 3 is given below:
| Type | If clause (condition) | Main clause (result) |
| Type 3 | Past perfect If + Past perfect continuous Could have + 3 | would Subject + could + have + V3 might |

Contractions
Both would and had can be contracted to 'd, which can be confusing if you are not confident with type 3 conditional sentences. Remember 2 rules:
1. would never appears in the if-clause so if 'd appears in the if clause, it must be abbreviating had.
2. had never appears before have so if 'd appears on a pronoun just before have, it must be abbreviating would.
Examples
- If I'd known you were in hospital, I'd have visited you.
- If I had known you were in hospital, I would have visited you.
- I'd have bought you a present if I'd known it was your birthday.
- I would have bought you a present if I had known it was your birthday.
- If you'd given me your e-mail, I'd have written to you.
- If you had given me your e-mail, I would have written to you.
