"I am reading that book."
Translation:Saya membaca buku itu.
What does the "tresebut" part mean? Does it initiate one is currently doing it?
'me-' prefix is used to create a verb from a base word.
The base word 'baca' is already a verb.
The difference in this case is the formality.
'membaca' is more formal.
There is no difference in meaning.
