When whites arrived in what is now known as America, there were approximately 300 distinct aboriginal languages and 600 dialects spoken by 1.5 million people. The majority of Native American languages were originally aural in nature, which allowed for a great ranges of expression, sounds and names. With many native languages, one word often conveys ideas that need a whole sentence in English.
Although they many appear innumerable, North American Indian languages have been categorized into six primary groups. The differentation between these groups was once determined by their region, however, the forced migration resulting from the arrival of the whites in the east caused the related languages of various tribes to be very distnaced from one another geographically.
