Thread:User talk:Amire80/Endonym for Nahuatl language

Hey Amir!

Marrovi, a Nahuatl Wikipedia editor I met at Wikimania, has asked me for advice on changing the endonym used for Nahuatl in MediaWiki/Wikimedia. (He says that the native name should be "Nahuatlahtolli" rather than just "Nahuatl"). I've asked him whether there was a community discussion, but haven't heard back yet.

How would the change be made? I read the FAQ on language names and looked at the CLDR website, but couldn't find anything for Nahuatl (nah) although I did see some references to specific dialects(?) of Nahuatl like Eastern Huasteca Nahuatl (nhe). Would we have to add a locale for nah?
