Some more basic ballet terms, are tendu and dégagé.

To tendu, slide your foot to the front(side or back), Making sure to have a pointed toe.

A dégagé can be done, when passing through tendu, and then lifting your foot slightly off of the ground.

*Remember: every step can either be done fast or slow. In ballet terms that would be petite allegro(fast) and Adagio(slow or at ease).
