Repetition. So called from a game which consists in some one
setting a line which another is to rhyme to, but no one word of the
first line must occur in the second.
Pantomime of a word in rhyme to a given word. Thus if “cat” is the
given word, the pantomimists would act Bat, Fat, Hat, Mat, Pat, Rat,
Sat, etc., till the word acted is guessed.
