A bending of the knees with hips, legs, and feet turned outward.
A gymnastics and dance movement. Most movements in ballet technique begin and end with a plié, which is a bend and stretch of the hip, knee, and ankle joints. Demi- and grand-pliés are done as an exercise at the beginning of the barre work and are done as half-bends and full-bends of the knee.
A basic bending movement of the knees; in French, it means "bent". This can be taken to demi-plié (a comfortable, natural bend) or grand-plié, where the dancer bends all the way down until their buttocks reach their feet, whilst maintaining classical turn-out.
