The Kurdish population is spread across several countries, including Turkey, Iraq, Iran, and Syria, among others. There are multiple dialects, as well. If someone wanted to study a single Kurdish dialect with the purpose of communicating with Kurds across each of these countries, is one dialect more preferable than the others?
My understanding is that Northern Kurdish is the most dominant, but is it comprehensible to the other dialects? Or is a smaller dialect more universally intelligible among Kurds? Or are all the dialects similar enough that it doesn't matter?
