Questions & Answers about Sekolah itu tidak punya guru tua lagi.
In Indonesian, demonstratives like ini and itu usually come after the noun.
- sekolah itu = that school / the school
- guru itu = that teacher / the teacher
So sekolah itu is the normal Indonesian order. In many contexts, itu can also make the noun feel more definite, so it can sometimes sound like the school, not just that school.
Because tidak is used to negate verbs, adjectives, and some other predicates, while bukan is mainly used to negate nouns or noun phrases.
Here, punya means to have, which is a verb, so:
- tidak punya = do not have
Compare:
- Sekolah itu tidak punya guru tua lagi. = That school no longer has old teachers.
- Itu bukan sekolah. = That is not a school.
So bukan punya would be wrong here.
