If you're looking for an introduction in Hassaniya basics, the U.S. Peace Corps covered Hassaniya basics in their traditional style language course which is now freely available online. You can find all of the older manuals on archive.org by clicking here. There are descriptions of each on their respective pages.
My personal favourite is the 'Communication and Culture Handbook' which contains good guidance to help one begin to fit in better!
Here's a snippet:
Livelingua.com have also made a webpage for the Peace Corps manuals. Added are 10 intro audio lessons that go with their first pdf 'Hassaniya Language Lessons', but their page is missing the 'Communication and Culture Handbook' cited above. Click here to go to the Live Lingua Mauritanian Arabic page
The pdf manuals are as follows:
- Hassaniya Language Lessons (only on Live Lingua with matching audio for the 10 short lessons)
- Mauritanian Arabic Primer
- Mauritanian Arabic Grammer
- Mauritanian Arabic Teacher's Handbook (Could be used to guide some initial lessons with a native speaker)
- Mauritanian Arabic Literacy
- Mauritanian Arabic Communication and Culture Handbook (only on archive.org)
