Muturzikin has an interesting collection of maps that outline the indigenous languages and dialects and accents of the English language throughout the United States. These language maps display the ethnic and linguistic complexities. Languages and dialects transcend geographical borders, where appropriate.
This site is committed to a different, more enlightening approach to cartography and seeks to preserve the integrity of the area in which the language or dialect is spoken, even where this crosses borders. The loss of linguistic diversity entails not only the disappearance of a large number of languages — and the cultural and identity loss that accompanies it — it also signals an important reduction of the genetic information which could help us understand the history of languages and the relationships different linguistic communities had in the past.
Linguistic diversity also shows typological information—that is, what is common or different in the structure of languages—and this kind of information helps us understand the nature and functioning of languages. When a language disappears, we also lose information about how different linguistic communities view reality and the most important to me, how their languages shape it.
We hope you enjoy the fascinating information this site has to offer and can incorporate the information into your lessons.
