Unknowing languages
<div>Everyone tell us what are the languages that not known for many people in the world </div>

<div>Most of the individual indigenous (native) languages of the Americas are not widely known.  You can know that there are still native Amerindian languages without knowing about Kumeyaay, for example.  This is the language of the native people in the southwestern-most area of the USA, where I live.  </div>
