Questions & Answers about Buku harian saya ada di atas meja.
In Indonesian, possession is usually shown by putting the possessor after the thing possessed.
So:
- buku harian = diary
- saya = I / me / my
Putting them together:
- buku harian saya = my diary
This is different from English, where my comes before the noun.
A similar pattern:
- rumah saya = my house
- teman saya = my friend
Buku harian is the normal Indonesian expression for diary.
Literally, it is made of:
- buku = book
- harian = daily / related to days
So the literal sense is something like daily book, but in natural English that becomes diary or sometimes journal.
This is a fixed, common expression. Native speakers understand buku harian as a diary, not just any book.
