Just as a note something I've noticed is that different teachers will have a slightly (or completly) different set of moves with the same name.

My teacher uses Arabic for certain types of foot movements:
ex. Arabic 1: flat-toe flat toe
Arabic 2: Flat-toe-toe flat-toe-toe

another studio that I once went to used arabic for the name if the lower undulation another used arabic for the walk with a lower undulation.
There doesn't seem to be a vocabulary that everyone agrees on. That shouldn't slow you from learning them, just know that you might get some conflicting information on this.

I'll let others with more experiance than I have explain in detail the moves themselves.
