Prove oneself fallible crossword clue
43 Across · WSJ Crossword, October 21, 2026 · 3 letters
Explanation
The answer to “Prove oneself fallible” is ERR. It appears as 43 Across in the Wall Street Journal crossword of October 21, 2026, a Wednesday puzzle titled “Rock Climbing” by Mike Graczyk, and it fills 3 squares running left to right from row 10, column 1 of the 15×15 grid.
The clue is a straightforward definition, so the answer is a direct synonym or a factual match for the words as written. The entry begins with E and ends with R, and contains 1 vowel and 2 consonants. If you are working from the crossings, two or three confirmed letters from the Down entries should be enough to lock it in. Wednesday puzzles sit mid-week on the difficulty curve, so expect the rest of this grid to be pitched at the same level.
