Conditional verbs and expressions: the unreal past

 

We use the unreal past to talk about unreal situations. Even though the verb is in the past tense, we use it to talk about situations that did not happen as well as to describe hypothetical situations that might exist now or at any time.

 

We use the unreal past after conditional words and expressions like ‘if only’, ‘I wish’, ‘would rather’, ‘should(n’t) have’, ‘would love/hate to’.

 

(I) wish/if only

 

We use (I) ‘wish’ and ‘if only’ to express wishes and regrets about things that may happen in the future or things that may have happened in the past. The tenses used depends on what we are trying to express.

When we use ‘wish’ to talk about things we want to be different in the present, we use ‘wish + Simple Past’.

• I wish I had more money. (but I don’t)
• She wishes she were famous. (but she’s not)

Note:  If the verb in the if clause is ‘to be,’ use “were,” even if the subject of the clause is a third person singular subject (i.e., he, she, it): If I were a rich man, I would make more charitable donations. If he were here right now, he would help us. Remember, though, that this exception applies only to unreal conditionals.

 

When we use ‘wish’ to talk about situations that happened in the past that we wish hadn’t happened or were different, we use ‘wish + Past Perfect’.

• I wish I had known then what I know now. (but I didn’t)
• He wishes he had asked her out before she left. (but he didn’t)

 

We use ‘if only’ for emphasis, and it follows the same rules as wish.

• If only I didn’t have so much homework to do, I could go with you tonight. (present unreal condition)
• If only you had told me you were coming, I would have made more food. (past unreal condition)

 

Would rather/it’s time

 

The expression ‘would rather’ is also followed by the unreal past. We use the past tense verb to talk about a situation in the present. When we want to talk about something that we would prefer someone else do or a situation that we would prefer go another way, we use ‘would rather + Past Simple’.

• I would rather you did it.
• He’d rather you didn’t hunt on his property.

*We can use the contracted form of would i.e., he’d, I’d, she’d, we’d, etc.

 

We use ‘it’s time’ similarly. When we want to suggest that it is a good time to do something – either for ourselves or someone else – we use ‘it’s time + Past Simple’.

• It’s time she went home now.
• It’s time you stopped that.

 

Should/shouldn’t have

 

When we use ‘should have’, it means something that we wish happened did not happen. When we use ‘shouldn’t have’, it refers to something that didn’t happen in the past that we wish did.

 

We use should(n’t) have + Past Participle.

• You should have told us. We were so worried! (but you didn’t)
• I shouldn’t have done that. (but I did)

*We often use ‘should/shouldn’t have’ in apologies.

 

Would love/hate to

 

When we talk about things or situations we want or hate but are unreal or hypothetical, we can use ‘would love/hate + infinitive (to + verb)’.

• We would love to go to the party. (but we can’t for some reason)
• I would love to visit Spain.
• I would hate to be you. (but I am not you)
• She would hate to leave the party early.
