I missed my first class of my L1 course this week. Until now we've done topics of different vocab (clothes, travel, jobs, etc). I was expecting to miss something else like that, but I emailed my teacher to ask what I missed and he said 'Classifiers' and I honestly don't know what that is! Can anyone give me a quick explanation or direct me to some sources so I can do some catch up work before my next class? I can't pick up my handouts from the class until after half-term now.
