I started studying Hindi just because I really like the way the Devanagari script looks. It’s challenging though. There are a lot of subtle sounds that we don’t have in English. And it’s hard to learn the symbol for a sound, when you can’t quite identify the sound itself or distinguish it from others that are similar! I’ll sort it out eventually, Deo volente.
Why not learn Sanskrit instead? That's what I'd choose if I wanted to use the Devanagari script for something...
Anyway, I am back to learning Japanese. Because I am in need of a language in order to graduate next semester... and Latin won't do, due to schedule conflicts. Plus, Japanese is probably something I'd get more benefit out of. (Latin seems relatively easy to pick up through self-study, if I ever need to learn it more than I already do. But Japanese is so different from what I'm accustomed to that I wouldn't even know where to start... and I'm probably going to need to learn it for my job in the near future...)
I'd tried (Mandarin) Chinese in the past but never made any progress. The tones were just too difficult for me, and I never made it to the grammar. I don't mind the writing system though. I'm currently having a fun time learning the thousands of Chinese characters (but for Japanese).
