See 54-Across

CROSSED

Think of what happens when two lines intersect at a right angle, like in geometry or on a pirate’s map.

This clue is a classic crossword trick where the answer is hidden in the instruction itself. "See 54-Across" is a red herring—the real answer comes from the word "crossed," which describes the act of looking at another clue (you "cross" to it). The pun lies in taking the literal meaning of "crossed" rather than following the direction, making the answer a playful nod to how solvers navigate the grid.
