From the clues’ extra words that shared one distinct letter with the answer, the letters spelt out “cruciverbal” (X). The other extra words gave “five letters, two-word phrase in which Zs exist”. Five grid letters were changed to reveal “crossword grid”, in an L shape in unchecked cells. The square of unclued entries contained “declined the option of opening the betting”, a Chambers definition of “checked” (Y), leading to “checked square” (Z), which Chambers defines as “a square in a crossword that belongs to the solution of two clues”.
