If I knew ... / I wish I knew ...
Second conditional and wish + past simple for unreal present situations
If + Past Simple for Imagined Present Situations
When you imagine something that is not real right now, use if + past simple. The meaning is present, not past.
- Sarah wants to call Paul, but she doesn’t have his number. She says: “I‘d phone him if I knew his number.”
- There are many things I‘d like to do if I had more time. (but I don’t have time)
- We live in the city, but we‘d need a car if we lived in the countryside.
- *If the office weren’t so far away, I‘d cycle to work every day.*
The if part uses the past simple. The other part uses would (or ‘d).
| If part (past simple) | Other part (would + base form) |
|---|---|
| If I had more budget, | I‘d hire another team member. |
| If she spoke Japanese, | she‘d handle the Tokyo account. |
| If we didn’t have a deadline, | we‘d take more time on the design. |
Wish + Past Simple for Regrets about Now
Use wish + past simple when you want the present to be different from what it is.
- I wish I knew Paul’s phone number. (= I don’t know it, and that’s a problem)
- Do you ever wish you could work from home? (you can’t)
- It’s very crowded in this open-plan office. I wish there weren’t so many people here.
- I wish I didn’t have to work this weekend, but I do.
Compare these two sentences:
| Sentence | Meaning |
|---|---|
| I’m glad I work near the station. | I work near the station, and that’s good. |
| I wish I worked near the station. | I don’t work near the station, and I’d like to. |
Were or Was after If and Wish
After if and wish, you can use were instead of was. Both are correct. Were is more common in formal writing.
- *If I were you, I wouldn’t sign that contract.(orIf I was you …*)
- I’d leave early if it weren’t so busy today. (or … if it wasn’t so busy …)
- I wish our manager were more flexible with schedules. (or … was more flexible …)
Don’t Use Would in the If Part
Put would in the result part of the sentence, not after if.
| Correct | Incorrect |
|---|---|
| *If I were rich, I would travel a lot.* | |
| Who would you ask if you needed help? |
The same rule applies with wish. Don’t use would to replace the past simple.
| Correct | Incorrect |
|---|---|
| I wish I had something to read. | |
| I wish she were here now. |
Could = Would Be Able To / Was Able To
Could sometimes means “would be able to” and sometimes “was able to.” Context tells you which.
- She could get a better position if she could speak another language. (she could get = she would be able to get; if she could speak = if she was able to speak)
- I wish I could help you with the report. (= I wish I was able to help)
- *If we could access the data, we‘d finish the analysis this week.*
