I know that "home" has no preposition. For example: I went home. He is home now.
But sometimes we say "He is at home." And I know it is correct too, because my teacher say it is the normal preposition for "home". But I sometimes hear "He is in Jack's home." Is it correct? I mean "in". If correct, can you please give me some examples with "in".
We usually use "at home" when the person in the sentence is in the place where they personally live.
I am at home = I am in my house.
Jack is at home = jack is in his house
I am in jack's home = I am in Jack's house
If Jack and I are both in Jack's house then I am in his home but he is at home.
