9. Difference between “wish+past simple” and “wish+past perfect”

1. Wish with Past Simple: We use this when we want to talk about things we want to change about the past, but they are still possible or could happen. It’s like saying, “I wish something different happened in the past, but it’s not too late for it to happen now.”Example: “I wish I had a pet dog.” (But I don’t have one. I can still get one.)
2. Wish with Past Perfect: We use this when we want to talk about things we want to change about the past, but they are impossible because they’re already done and can’t be changed. It’s like saying, “I wish something different happened in the past, but it’s too late for it to happen now.”Example: “I wish I had studied for the test.” (But I didn’t study, and the test is already over. I can’t change it now.)

So, the main difference is that “wish + past simple” is used for things that could still happen, while “wish + past perfect” is used for things that are impossible to change because they’re already done.
