Consider integrating freq lists from Bangla-Tangla
FYI, a Bangla / বাংলা frequency list (seems to reflect both stems and real-life text) is on the site http://www.banglatangla.com/. Seemed worth at least letting you know--I'm just now getting back into RL again. :-)
Thanks, I’ll have a go at parsing the data and getting it into Readlang. I suppose it’s not a perfect representative sample since it’s generated from a corpus of newspapers, but better than nothing.
