English often uses past forms to talk about unreal, imagined, or desired situations in the present or future.
Use past simple after wish, if only, would rather, and it is time for present or future meanings.
Use past perfect when the regret or unreal situation refers to the past.
| Use | Pattern | Example |
|---|---|---|
| Core form | wish / if only + past simple | I wish the process were simpler. |
| Variation | wish / if only + past perfect | If only we had checked the data earlier. |
| Advanced form | would rather / it is time + past simple | I would rather you dealt with this today. |
Use were instead of was in formal unreal clauses: I wish it were easier.
Use would after wish mainly to complain about repeated behaviour: I wish they would reply.
