Ballet terms

I really should start remembering those ballet terms so that I have less problem remembering those combinations . I spent most of my time recalling what I need to do instead of doing the combination. The instructor Grace today was definitely easier than Naomi. So I should had even less excuse to complain about the difficulty.

My question was, what was the best source to find the mekong of all these terms?

And then I got home, and I found that I have several of those book all describing ballet terms. That's when I realized that I had that need ... like ... 10 years ago. And sadly, after these 10 years, I still haven't mastered these terms.
