Quiz \Quiz\ (kw[i^]z), n. [It is said that Daly, the manager of
   a Dublin playhouse, laid a wager that a new word of no

   were chalked by him on all the walls of Dublin, with an
   effect that won the wager. Perhaps, however, originally a
   variant of whiz, and formerly the name of a popular game.]
