Ballet is a formalised form of dance with its origins in the Italian Renaissance court, further developed in France and Russia as a concert dance form. It is a highly technical form of dance with its own vocabulary. It has been influential as a form of dance globally and is taught in ballet schools around the world. Ballet dance works (ballets) are choreographed, and also include mime, acting, and are set to music (usually orchestral but occasionally vocal). It is best known in the form of classical ballet, noteable for its techniques, such as pointe work, turn-out of the legs; its graceful, flowing, precise movements; and its ethereal qualities. Later developments include neoclassical ballet and contemporary ballet. The etymology of the word "ballet" is related to the art form's history. The word ballet comes from French and was borrowed into English around the 17th century. The French word in turn has its origins in Italian balletto, a diminutive of ballo (dance). Ballet ultimately traces back to Latin ballere, meaning to dance.
