vocabulary.

Hi, teacher.... what do I know about vocabulary? well I realised today that I probably know somethings but I still don't know enough.
I was reading an article about kendall jenner at New York's Fashion Week and even being an article about fashion, there were a lot of unknown words for me, I had to look for the meaning and that was annoying....I think I have to learn and to study because I really want to know about English, I mean I am studying for being a teacher I want to do my best.... Hope to do it! :D
