Number that’s neither prime nor composite crossword clue
62 Across · WSJ Crossword, June 29, 2026 · 3 letters
Explanation
The answer to “Number that’s neither prime nor composite” is ONE. It appears as 62 Across in the Wall Street Journal crossword of June 29, 2026, a Monday puzzle titled “Margin of Error” by Mike Shenk, and it fills 3 squares running left to right from row 15, 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 2 vowels and 1 consonant. 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.
