Do these two Japanese sentences mean what I think they mean?
kono uchi ni hon ni arimasuka
kono uchi ni hon deska
I think the first one is "is there a book in this house" and the second one is "is the book in the house"
am i correct? please explain thankyou
Neither of these sentences is actually grammatically correct.
In the first one, if you really want to say "is there a book in this house," you would need to say "kono uchi ni hon ga arimasu ka?" Ni is the wrong particle because "ni" shows location. When you say "kono uchi ni" the "ni" shows the location of the action, which is in the house. But the book is not the location of the action, so you don't say "ni" with regard to the book.
To say "is the book in this house" you would need to say "hon wa kono uchi ni arimasu ka?" You put "hon" with the "wa" to show it's the subject. You put "ni" with "uchi" to show that that is where the action (being -- "arimasu") is taking place.
Neither of the sentences as they are written can actually be translated because neither of them is grammatically correct.
