While the Kurdish language is spoken by millions, it's important to understand that:
* Kurds are not a monolithic group: There are various dialects of Kurdish, with Sorani and Kurmanji being the two most widely spoken.
* Not all Kurds speak Kurdish: Some Kurds may speak other languages as their native tongue, especially if they live in a region where another language dominates.
* Language is not a defining factor of identity: Some people who identify as Kurdish may speak other languages, and some people who speak Kurdish may not identify as Kurdish.
Therefore, it's inaccurate to say that all people who speak Kurdish are Kurds, or that all Kurds speak Kurdish. The best way to understand the relationship between language and ethnicity is to recognize that they are complex and interconnected, but not always directly linked.
