It's about a language lesson. There are 2 languages in the lesson : the taught language and the language used to describe and explain the lesson. "Language used to comment the lesson" represents the latest.
I need more info to know if this is a good translation or needs some very slight editing to be correct. Where is this phrase from? Some more context would be much appreciated.
