“I wish” expresses desires or regrets about unreal situations. Here are three ways to build your wish:

  1. I wish I did something (past simple)
  2. I wish I had done something (past perfect)
  3. I wish someone would do something (would + infinitive)

1. Past Simple

It expresses a desire for something or someone to be different right now or in the future.

  • I wish things were different, but this is the way they are.
  • I wish I had enough money to help you.
  • I wish I could be there for you tomorrow.

2. Past Perfect

It allows us to express regret for something we didn't do in the past.

  • I wish I hadn’t quit my job two years ago.
  • I wish we hadn’t wasted all that money.

3. Someone would

To gently nudge someone towards changing an annoying behavior.

  • I wish you would stop biting your nails. I hate it when you do it.
  • I wish it would stop raining. It’s been three days!

If only

“If only” carries the same wish as “I wish,” but with a stronger punch.

  • If only I was/were a bit taller! (First type)
  • If only you had followed my advice. (Second type)
  • If only you would make a bit of an effort. You are wasting your life! (Third type)
