How do you say "I have a brother." in Mongolian? I found out that you can say it in a few different ways. Би ахтай. / Надад ах байдаг. / Надад ах байгаа. But I don't really know if there is any difference between those sentences. And also with the questions: Чи ахтай юу? / Чамд ах байдаг уу? / Чамд ах байдгаа юу? Is there any difference? Does it mean the same? Is any of those sentences right :D ? Thank you! Баярлалаа
