 Determining which clue is to be applied to which grid is part of the puzzle.Any type of puzzle may contain "cross-references", where the answer
to one clue forms part of another clue, in which it is referred to by number and direction.E.g., a puzzle might have 1-Across clued as "Central character in The Lord of the Rings" = FRODO, with 17-Down clued as "Precious object for 1-Across" = RING.
