Malayalam at the moment. Native tongue, but unfortunately rusty in expressing things in without resorting to english words. Basically trying to go from native speaker who is fine with colloquial tongue to literature oriented, mildly fancier writing. Probably need to read a ton of literature.
Going beyond colloquial Malayalam is quite painful (kinda diglossic language). Tried to read some books and the frequency of dictionary look ups can be very demoralising lol (And a very specific annoyance of e-reader dictionaries sucking because its a heavily inflected language).
I've been wanting to learn other Indic languages (Tamil - sister language to Malayalam basically, Bangla, Hindi) and Spanish. I maybe getting too ambitious.
