sauté, which is done 
with a spring from the 
fifth position and finishes 
in a demi-plié in 
second position, and 
échappé sur

demi-pointe, which is done 
with a relevé and 
has straight knees when in 
second position. In each

from the center of 
gravity.

An assemble is when you throw one leg up and springs off the other, while ascending the raised leg continues to rise, landing on both feet closed together back in fifth. Assemble can travel in the direction in which the leg was raised, and can be performed while turning, or with a beat. 
Here is an attached video of how to do it.
