How ballerinas dance can be described as lithely, ontoe, and on tiptoe. Lithely means to move gracefully and with agility, which is a key component of ballet dancing. Ontoe is a term used to describe the position of the feet when the dancer is standing on the balls of their feet. On tiptoe is a similar position, but with the dancer standing on their toes instead of the balls of their feet. All three terms are used to describe the graceful movements of a ballerina.
