A seven-cell sweep across two rows
Trace CATHODE from row 7, column 5. Move right twice to collect A and T, turn up for H, and then travel left through O, D, and E. The complete letter sequence is C → A → T → H → O → D → E, ending at row 6, column 4.
Follow these positions in order: 1 at row 7, column 5; 2 at row 7, column 6; 3 at row 7, column 7; 4 at row 6, column 7; 5 at row 6, column 6; 6 at row 6, column 5; 7 at row 6, column 4. This path has two turns and three straight segments. It visits four edge cells and one corner cell, giving you a compact geometry check beyond the spelling.
