"Kami punya buku-buku ini."

Translation: We have these books.

[kousuke.na1]

Does this sentene also mean "we belong to these books" ?

[Aiden212598]

No, it doesn't mean that.

Kami milik buku-buku ini, would be that way of saying it.

[jessm.jm]

Your sentence has different meaning. "We have these books" loosely mean "these books belong to us" (if you change the structure and verb), not otherwise.

I wrote "We have the books" and it marked wrong.
Is it wrong to use "the" instead of "these"??
