"He writes a book."
Translation:Dia menulis buku.
Really? I thought it was "the book I borrowed" or that's what I barely was able to find in the internet.
I received a translation that said "Ia menulis buku" instead of dia menulis buku. What is the difference between "Ia" and "Dia" and how do I know which one to use?
They both have the same meaning, but "ia" is more formal than "dia". In writing exercise, your answer should be correct. But if it was listening exercise, you should write exactly what the speaker said.
