Conversation Between グレッグ and beatrixkiddo

年　= ねん = year

On and off for about 2-3 months.

I don't get to study it in serious mode as I have university to do which is completely language unrelated for me.

Anyway, I think I understood everything in your sentence even though the structure was a little wonky for me. Everything except "年" never seen it before.

グレッグさんは何年ぐらい日本語が勉強したか？
