Triatomic oxygen crossword clue
14 Across · WSJ Crossword, July 27, 2026 · 5 letters
Explanation
The answer to “Triatomic oxygen” is OZONE. It appears as 14 Across in the Wall Street Journal crossword of July 27, 2026, a Monday puzzle titled “Brief Exchange” by Mat Holmes, and it fills 5 squares running left to right from row 2, 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 O and ends with E, and contains 3 vowels 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. Monday puzzles are the most approachable of the week, so expect the rest of this grid to be pitched at the same level.
