I’ve added a new Links section over on the righthand side of the page, called Nahuatl Language. That section is where I’m linking material around the Net that relates to learning Nahuatl, particularly Classical Nahuatl (the language as it was a few hundred years ago). This stuff is always handy for reference, and to get your feet wet if you’re interested in learning how to read some of the primary sources that were written down in that tongue after the Conquest.
These links relate to reading Nahuatl written alphabetically, not reading the glyphs/pictographs that were used in the Codices prior to the Spanish invasion. I’m looking for material online that teaches a bit about the glyphs, though, and will link what I find.
Finally, the links in there now are in a mix of languages. Molina’s classic textbook and dictionary are antique Spanish and Nahuatl; I included them for those who can read old Spanish (not me!) and due to their foundational significance in the study of the language. The html version of Renee Simeon’s 1885 dictionary is Nahuatl to French, but I would expect the numerous free online translators could handle the short snippets of relatively-recent French without much trouble.
For my English-language audience, the Nahuatl Learning Environment is available in English (it’s also available in Spanish). Just log in with the ID and password noted in the link title (repeated in the tooltip if you hover your mouse cursor over it), and you’re good to go — there’s no registration or anything like that. Finally, the Freelang Nahuatl dictionary is a Nahuatl-English dictionary, and can be downloaded for offline use, or used via the web. Handy and free!
I’ll do a post sometime soon on basic pronunciation to go with all these links. I’ve seen the very formal charts on pronunciation that use the technical symbols and whatnot, but frankly I can’t read them, and I don’t know many who can. If you have a copy of Frances Kartunnen’s Analytical Dictionary of Nahuatl, I find her notes on pronunciation to be the most helpful I’ve come across.
Anyway, enjoy, and I’ll add more to this section as I find it.
