Tach abbr. crossword clue
1 Across · WSJ Crossword, October 28, 2026 · 3 letters
Explanation
The answer to “Tach abbr.” is RPM. It appears as 1 Across in the Wall Street Journal crossword of October 28, 2026, a Wednesday puzzle titled “Jump Scares” by Mike Shenk, and it fills 3 squares running left to right from row 1, column 1 of the 15×15 grid.
The shortening cue in the clue tells you to expect an abbreviation or initials rather than a full word. The entry begins with R and ends with M, and contains 0 vowels 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. Wednesday puzzles sit mid-week on the difficulty curve, so expect the rest of this grid to be pitched at the same level.
