Corrosion found in the four longest Across answers crossword clue
73 Across · WSJ Crossword, August 16, 2026 · 4 letters
Explanation
The answer to “Corrosion found in the four longest Across answers” is RUST. It appears as 73 Across in the Wall Street Journal crossword of August 16, 2026, a Sunday puzzle titled “Corrode Test” by Zhouqin Burnikel, and it fills 4 squares running left to right from row 15, column 12 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 R and ends with T, and contains 1 vowel and 3 consonants. If you are working from the crossings, two or three confirmed letters from the Down entries should be enough to lock it in. Weekend puzzles follow the same conventions as the weekday grids, pitched a notch above midweek, so expect the rest of this grid to be pitched at the same level.
