Developpe

This is a movement that works the leg and draws up from the knee while standing on the other supporting leg. It is a movement that is slowly extended from the hip to the knee through the ankle and into the foot and is held in the air as high as possible. Maintaining perfect control and keeping your hips level and supporting leg straight and posture straight as well.

Chasse

This is pronounced as (shaw- say). Which means to literally chase the other foot. You will start in right third position. You will slide your right foot out to a second position, then straighten your left leg and transfer you weight so that there is no weight on the right leg, then close in left fifth.
Here is a video to demonstrate.

Grand jete

A Grand Jete in english is simply a leap. How you start to approach a leap, is you start in left fifth position, and draw your right foot back as if you're pointing it backward, this is called the B+ position. This is where you begin a leap, next you're going to step right then left both being in plie. You will then spring off your left and split in the air with your right leg leading, just as shown in the picture. This is applied to any leap the foot work just might be different depending on the leap.
