This piqued my curiosity so I dug out my dictionary and found...
The first definition of "ballet" in the Canadian Oxford Dictionary (thumb index edition) is: "a theatrical style of dancing using set steps and techniques and characterized esp. by movement with the legs turned out in the hip sockets and by the women dancing on pointe"
Finally...a mention of of turnout and pointe!
There are further definitions about it being a theatrical work using ballet, a music piece composed for a ballet, a performance of ballet, and a company perofrming ballet.
