Wish
"Wish" is usually followed by a clause beginning with "that". You can often leave out "that". If you wish (that) something was true, you would like it to be true, although you know it is unlikely or impossible.
e.g. I wish (that) I lived nearer London.
e.g. I wish (that) I could paint.
If you wish that something would happen, you want it to happen, and you are angry, worried or disappointed because it has not happened already.
e.g. I wish he would come!
e.g. I wish you would try to understand.
Don't use "wish" with a clause to say that you hope something good will happen to someone. Don't say, for example, "I wish you'll have a nice time in Finland". Say "I hope you'll have a nice time in Finland" or "I hope you have a nice time in Finland".
e.g. I hope I'll see you before you go.
e.g. I hope you like this village.
However, you can use "wish" followed by "you" and a noun phrase to say that you hhope something good will happen to someone. For example, if you say "I wish you a happy birthday", you mean "I hope you have a happy birthday".
e.g. I wish you both a good trip.
