The extra words in clues to the four entries that bordered the central area were “promise to settle up”, wordplay leading to “word square”. The central 6×6 area was a word square containing CIRCLE, INURES, RUDEST, CREASE, LESSEE, ESTEEM — thus “squaring the circle”, an impossible task in Euclidean geometry using only a straight edge and compasses. Bars were entered to form the boundary of the word square, and normally in the rest of the grid, forming real-word entries everywhere.
