Learn hindi... would be better grammar (Naan is used in multiple Indian languages and not exclusive to hindi by any means).... Interestingly naan has it's roots in Persia and Afghanistan. And strictly speaking not even Indian.
The most common form of bread in India is still roti.
Isn't Hindi a language?
That's saying 'Learn the language language, people!' you daft cunt.
'The English language' makes sense, as it's the language of the English
'The Hindi language' isn't the language of the Hindi.
(fully expect @Oliver Schick to correct me, but I've amused myself in the meantime)
