As far as the US is concerned, it is a melting pot of several cultures. However, there are several native languages in the US that are barely known, because most of the communication takes place in English. Before English became the officially recognized language in the US, there were many native languages, about 300 in all. However, colonization and globalization have led the death of many of the native languages in the US. Among the various native languages, Navajo happens to be the most popular. There are about 170,000 people who speak this language, and the Navajo has also been able to include some of the modern technological terms into its vocabulary.
The next most spoken native language happens to be Yupik and Sioux. Yupik is a native language spoken by natives in Alaska. The Sioux language has a total of three different dialects and is spoken mostly in Nebraska, Minnesota and North and South Dakota. The Apache language has five groups. Among the native languages, the most unique is the Cherokee. What is interesting about this native language is that it has incorporated some roman alphabets and have taken a lot of effort to preserve their language for future generations.
There was a time when the US had an unbelievably large number of native languages spoken inside its borders. However, over time, and with the concept of globalization, things have changed, and a lot of languages that were previously spoken are now extinct, with many other dying a slow death. The reason for this is the colonization era, when white settlers from the European continent murdered a large number of natives in the US, sometimes wiping out even 90 percent of an entire native population, often through unfair means. All this lead to the large-scale death of the native population through disease, sicknesses such as smallpox (brought by the Europeans to kill the natives).
As of now, there are a minority of native languages still spoken by native communities in the US. Before the arrival of Columbus, there were about 300 native languages, but many are extinct now. Some of these native languages that continue to be spoken among Native Americans are Navajo, Yupik, Dakota, Apache, Keres, Cherokee, Ojibwa, Choctaw, Zuni, and Pima. Of these, Navajo is the highest spoken among native languages and Pima is the least spoken. English is the official language, most of these languages are spoken only by a minority.
