I want to learn Marwari- translation

So when you start learning a language, it so happens that you ask someone who is very much familiar with it to teach you. You can simply go tell the person to teach you the language. No big deal. But just to make sure the person teaching you takes you seriously, start with saying the same phrase in the language you want to learn. In our case it is  Marwari.

I want to learn Marwari

Translation:

Mahnne Marwari seekhno hai.
or
Mahnne Marwari seekhni hai.

Here, the former is typical Marwari and the latter is Marwari mixed with Hindi. The latter is mostly used when you want to ask in a formal way.
