My family is mostly from Tamil Nadu in India, so we speak mainly Tamil at home. i'm considering some independent travels this summer to Kerala for sight-seeing, and thought about learning some Malayalam. i wanted to know, how hard/easy do you think it will be, given Tamil knowledge and background? the only other experience/knowledge of Indian languages I have, is Hindi and i don't think that's very useful when it comes to any of the Dravidian languages!
would it be very difficult to learn at first, are the two (Tamil and Malayalam) extremely different? Just wondering, if anyone has had experience learning either of these or multiple Indian languages and would share their experiences, difficulties, etc.
