Bilasáana ’éí neeznáá shee dahólǫ́. But in reality, we don’t often say "I have ten apples" we treat it more like 10 apples exist. For example, "Díkwíí (lá) Bilasáana (hólǫ́)?" or "Bilasáanaásh (’éí) díkwíí? : Bilasáaná ’éí neeznáá. But again, normally most Navajos would say for example, "Díkwíí bilasáana" or "Bilasáana ’éí díkwíí lá sinil?" As you can see, there are many different forms as to how to ask a question and one will sound better or the best depending on the situation.
I hope that this all makes sense. It is difficult for me to explain how it works and why it works that way. I just know how my language works and how to respond to such situations.
