Brain check: Abbr. crossword clue
55 Across · WSJ Crossword, July 10, 2026 · 3 letters
Explanation
The answer to “Brain check: Abbr.” is EEG. It appears as 55 Across in the Wall Street Journal crossword of July 10, 2026, a Friday puzzle titled “Let’s Change Places” by Matt Gaffney, and it fills 3 squares running left to right from row 12, column 9 of the 15×15 grid.
The shortening cue in the clue tells you to expect an abbreviation or initials rather than a full word. The entry begins with E and ends with G, and contains 2 vowels and 1 consonant. If you are working from the crossings, two or three confirmed letters from the Down entries should be enough to lock it in. Friday puzzles are the Journal’s contest crosswords with a hidden meta answer, so expect the rest of this grid to be pitched at the same level.
Past appearances
