Hi, The answer from Ungu is perfect! And for bonus tip - you can add "bukan" at the end of a sentence, or just "kan" for short, when speaking ... In English it would be the same as "..., isn't it?" Like this: Anda guru bahasa Inggris, kan? -- you are an English teacher, aren't you? Kamu sudah pernah ke sana, kan? -- you have already been there, haven't you? Tapi toko itu sudah tutup kan? -- but that shop is already closed, isn't it? Kacisnya mahal kan? -- the ticket is expensive, is that right? (Sorry if it's not 100% accurate, I am still learning indonesian) Indonesian people - are these examples correct? Or do they sound wrong?
