[F. (16th c. in Littré), noise, disturbance, rumpus, also the dance. Of uncertain etymology, the popular fancy being that it is the L. quanquam, about the proper pronunciation of which a noisy wrangle is said to have occurred in the French schools. But Littré also points to an OF. caquehan tumultuous assembly; Scheler thinks it the vbl. sb. from cancaner, which he thinks was to quack as a duck.]
