When I was a dance student in the 70s and 80s teachers exclusively used the word 'enchaînement' in ballet classes for what was called a 'combination' in Modern, Jazz, or Tap classes. I've recently noticed that almost everybody says combination now in ballet classes and almost no-one (apart from me, it seems) says enchaînement. When did this happen and is anyone old enough to have noticed?
