I wish....
1. We can use wish + infinitive to mean want. 'Wish' is more formal.
I wish to see the manager, please.
2. We can also use wish to express regrets - to say that we would like things to be different. We use a past tense with a present meaning in this case.
I wish + subject + past tense
I wish I was better-looking.
I wish I spoke French.
I wish I had a yacht.
I wish it wasn't raining.
In formal style, we can use were instead of was after I wish.
I wish I
