Why cant bukan be used?
Negation: Tidak, bukan, jangan, belum, Tips & Notes, Addendum.
From what I understand from Rick's link, bukan is used for nouns and tidak is used for verbs. Is that correct?
I received this question as multiple choice and the correct option was tak suka instead of tidak suka. What is the difference between the two? Is it just an abbreviated form?
Yes. "Tak" is the abbreviated form of "tidak".
However, using "gak" or "enggak" Instead of using 'tidak' is more common than using "tak".
Tahu is food and "know"?
Yes, but "tahu" as "know" is commonly written as "tau" for the informal form, then you can use "tahu" when using a formal one. Hope this helps :)
This is me 100%
I got it wrong but writing looks exactly the same
