If you expect something to happen, you believe that it will happen, whether you want it to or not. If you hope something will happen, you want it to happen. If you wish that something will happen, you really hope that it will happen, but believe that it probably will not.

Expect- You have reason to believe something's going to happen. Hope- You desperately want something to happen. Wish- You're saying magic words in your head (or upon some external object) to make it happen. Examples: "I expect that tomorrow it will rain. I expect this because the local meteorologist has come to the same conclusion and because a tropical storm is moving up from the south." "I hope I'll be able to see my mother one last time before she dies. I'm driving as fast as I can to the hospital, but she doesn't have much time left." "I wish for a million dollars. Since I wished to the north star this time, I should get lucky!" Obviously, "expecting" is little more than "reasonably predicting". "Hoping" is grounded in reality, knowing that you can't change the outcome of an event but desiring that it works out like you've envisioned. "Wishing" is lofty and unreasonable, seeing as magic, you know, isn't real. However, people will occasionally use "wish" when they actually mean "hope", like, "Best wishes on your job interview!", and vice versa with "hope" and "wish", like, "Now that I flung a penny into the wishing well, I hope that I meet the man of my dreams on the subway tonight!" They're not the same word, but colloquially you can get away with treating them as synonyms and then figuring out what a person ACTUALLY means through context; if the thing they're hoping/wishing for is reasonable but uncertain, then it's "hope", and if the thing they're hoping/wishing for is absurd and highly implausible, then it's "wish".

in general use, they have practically no major difference, one can have as many of them as they wish to! 'Expect' is not a noun, but other 2 are both- noun and verb. all of them can be used subjunctively. u can expect/hope ur wishes come real, u can wish to have more/less wishes, wishes are in some cases translatable to hopes, expect sounds more materialistic while hope and wish have a rather abstract sense. u expect ur pizza be ready in 5 minutes. u hope ur friend will like the pizza. in a hot summer evening, u wish the pizza comes with a free apple juice. without question each of them has a unique literary taste, u expect good year/ u wish to have a nice friend/ u hope ur wishes come true. of the three, expect represents the strongest likelihood of coming true, realistic(common), or highly unrealistic(rare)- one can expect a miracle too! hope sounds more naive, lacking reality sometimes, mostly impersonal. wishes r less frequent, more endearing, more personal.
