Go home/ Come home/ Come back home/ Come back to home?????
In my opinion, "Come home" and " Go home" can be used in the same way.
One time, when I said : "I wanna come back to home", my friend told me it's wrong. "Come back home" only, not "to".
But my teacher said: "There're no come back home or comeback to home", we can only use "Come home" or "Go home"
I feel confused =''=
And really need your help.
Thank you!

Answer

"Go home" is from a point of view not at home.
"Come home" is from a point of view at home.
"Come back home" would be used if someone has been gone a long time.
"Come back to home" is wrong.
