WISH
' I wish to' can mean the same as 'I want to' but it is much, much more formal and much, much less common.
I wish to see the manager.
You can also use 'wish' with a noun to 'offer good wishes'.
We wish you a merry Christmas.
Notice that when you want to offer good wishes using a verb, you must use 'hope ' and not 'wish'.
We wish you the best of luck.
We hope you have the best of luck.
However, the main use of 'wish' is to say that we would like things to be different from what they are, that we have regrets about the present situation.
I wish I was rich.
Notice that the verb tense which follows 'I wish' is 'more in the past' than the tense corresponding to its meaning.
I'm too fat. I wish I was thin.
It's raining. I wish it wasn't raining.
In the case of 'will' , where 'will' means 'show willingness' we use 'would'.
He won't help me. I wish he would help me.
Where 'will' means a future event, we cannot use 'wish' and must use 'hope'.
I hope everything will be fine in your new job.
In more formal English, we use the subjunctive form 'were' and not 'was' after 'wish'.
I wish I were taller.
I wish it were Saturday today.
I wish he were here.
