Cornerstone abbr. crossword clue
57 Down · WSJ Crossword, October 8, 2026 · 4 letters
Explanation
The answer to “Cornerstone abbr.” is ESTD. It appears as 57 Down in the Wall Street Journal crossword of October 8, 2026, a Thursday puzzle titled “Endless Discussion” by Mike Shenk, and it fills 4 squares running top to bottom from row 12, column 15 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 D, and contains 1 vowel and 3 consonants. If you are working from the crossings, two or three confirmed letters from the Across entries should be enough to lock it in. Thursday puzzles lean harder on misdirection, so expect the rest of this grid to be pitched at the same level.
