5I wish to leave on holiday = I want to leave on holiday, right?
Roughly. It is rather formal.
We say "I want someone to do something", but if I replace "want" with "wish" in a more formal style how should I say? Is "I wish that he would help me" equivalent to "I want him to help me"?
No. "I wish that he would help me" conveys the idea that he is not helping you, or that he will not help you.
