Flash of light crossword clue
50 Down · WSJ Crossword, September 17, 2026 · 5 letters
Explanation
The answer to “Flash of light” is GLINT. It appears as 50 Down in the Wall Street Journal crossword of September 17, 2026, a Thursday puzzle titled “Whatever Works” by Matt Gaffney, and it fills 5 squares running top to bottom from row 11, column 9 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 G and ends with T, and contains 1 vowel and 4 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.
