A Unique Verb

Wish follows a unique -- and rather confusing -- set of grammar rules. Wish uses the same verb back shifting rule as reported speech.

A wish about the present uses a simple past main verb.

He wishes he understood the lesson.

In this example, understood is a simple past verb.

Wish is often followed by that. That introduces a noun clause. It is optional. For example:

I wish that I looked like a movie star.
I wish I looked like a movie star.

Both of these sentences have the same meaning.

In hypothetical situations, such as wishes and conditionals, use were for all pronouns.

I wish you were here.
I wish she were here.
I wish I were there.

In everyday conversation, you might hear was after wish. For example, “I wish I was the president.” Was is acceptable in informal situations, but you should use were in formal situations. This confusing rule comes to English through Latin.

Future wishes

Wish followed by would usually implies a request. For example:

I wish you would finish college before you get married.

Wish can be used after be going to or will to predict a future regret. Maybe you have heard your parents say something like this:

Someday, you are going to wish you had taken my advice.

When you are older, you will wish that you had studied engineering.

Past wishes

Let’s take a closer look at past wishes. Generally, a past wish is a wish that did not come true. To refer to a past wish, use a past perfect verb after the object. To form the past perfect, use had followed by a past participle verb.

She wishes she had written down the phone number.

I wish I had known that you were in town last week.

Listen to country singer Gene Autry make a past wish in an old song called “I Wish I Had Never Met Sunshine.” In this song, Sunshine is the name of a lost lover.

I wish I had never met Sunshine, and Sunshine had never met me
For 21 years I'll regret it 'Cause I'm in the jailhouse, you see

Most of the time, a wish about the past suggests regret. The speaker would have acted differently if he or she could turn back time. A past wish has a similar grammatical function to a past unreal conditional.

Listen to this song by Taylor Swift. You will hear three different uses of wish. She starts with a future wish, then shifts to the past, then to the present.

I wish you would come back (future)
(I) wish I (had) never hung up the phone like I did (past)
I wish you knew that I'll never forget you as long as I live. (present)
I wish you were right here, right now it’s all good (present)

Wish + infinitive

Wish followed by an infinitive makes a strong demand. For example:

I wish to speak to the manager.
I wish to learn the truth about what happened.

Wish can be followed by an infinitive, but never by a gerund. For example, it would sound strange to say, “I wish going skiing.” The correct form is, “I wish to go skiing.”

Hope vs. Wish

What’s the difference between hope and wish? In some contexts they can be interchangeable. Hope usually expresses desire that is possible. Wish, on the other hand, refers to an outcome that is not likely to happen.

Pay attention to the different contexts of hope and wish in these examples.

I hope you pass the test. (possible)
I wish I could fly. (impossible)
I hope I get to work on time. (possible)
I wish I were a millionaire. (not likely)
If wish is “reaching for the stars,” then hope is “reaching for the sky.”
