Editing Tone (linguistics) (section)

===America===
A large number of North, South and Central American languages are tonal, including many of the [[Athabaskan languages]] of [[Alaska]] and the [[Southwestern United States|American Southwest]] (including [[Navajo language|Navajo]]),{{sfnp|Kingston|2005}} and the [[Oto-Manguean languages]] of Mexico. Among the [[Mayan languages]], which are mostly non-tonal, [[Yucatec Maya language|Yucatec]] (with the largest number of speakers), [[Uspantek language|Uspantek]], and one dialect of [[Tzotzil language|Tzotzil]] have developed tone systems. The [[Ticuna language]] of the western Amazon is perhaps the most tonal language of the Americas. Other languages of the western Amazon have fairly simple tone systems as well. However, although tone systems have been recorded for many American languages, little theoretical work has been completed for the characterization of their tone systems. In different cases, Oto-Manguean tone languages in Mexico have been found to possess tone systems similar to both Asian and African tone languages.{{sfnp|Yip|2002|pp=212–14}}
