I've noticed languages are kind of a thing, with some talks of communicators. I had to look up if rodians can even speak basic, sources are mixed, but both the clone wars show and wookipedia claim yes, so I declare Kogo can speak broken basic, as well undetstanding  Huttese and droid speak. 

Might not be a bad idea for everyone to add a languages section if you don't have one yet. 

Overcoming language barriers could be interesting.
