Which Puzzles Use Letter After Sigma Crossword Clue For Answer Tau?

Whenever I’m working through a themed weekend puzzle or a quick weekday grid, clues like “letter after sigma (3)” make me grin — they point directly to tau. In plain American-style crosswords you’ll commonly see short, literal clues that expect the solver to know the Greek alphabet order: rho, sigma, tau, upsilon. Constructors phrase this in lots of small ways: “Greek letter after sigma,” “follows sigma,” “19th Greek letter,” or simply “letter after σ.” Those are all basically asking for three letters, and that little trio—T-A-U—fits perfectly into intersecting entries. I love how economical these clues are; they’re tidy little nods to classical knowledge that reward a solver who’s brushed up on the alphabet. British cryptics sometimes handle the same idea a bit differently. A straight definition could still be “letter after sigma,” but you’ll also find more playful surfaces: an &lit that hints at both position and shape, or a clue where 'sigma' is treated as a wordplay component that leads to the same three-letter result. Puzzle hunts and variety puzzles might use the phrase as part of a larger meta or to indicate a letter to extract — for example, “letter after sigma” could signal the next letter in a coded Greek sequence rather than simply listing 'tau' in the grid. Educational crosswords, math worksheets, and trivia quizzes also reuse this phrasing a lot, sometimes alongside physics clues because 'tau' shows up in torque and time-constant contexts, or in fun math puzzles referencing the constant τ = 2π. Practical tip from my own solving: if you’re stuck on a crossing and you see something like A with a theme hint about Greek letters, plug in 'tau' mentally and see if the across or down entries make sense. It’s a tiny victory when a stubborn corner clicks because of a neat little clue like that. I still get a small nerdy thrill whenever a simple “letter after sigma” clue hands me a clean three-letter fill that opens up the rest of the grid.

Lately I’ve noticed the phrase 'letter after sigma' popping up across a surprising spread of puzzle types, and it almost always maps straight to tau. In quick American crosswords and puzzle apps the clue is usually literal — think “Greek letter following sigma” or “19th Greek letter” — and constructors expect you to supply the three-letter Greek name. In cryptic puzzles the same idea can be dressed up with wordplay or cast as a definition within a clever surface, but the target remains the same: tau. Beyond standard crosswords, you’ll see the wording in trivia rounds, educational worksheets, and some puzzle-hunt clues where positional language matters for extraction. Physics or math-themed puzzles sometimes clue tau in other ways too, like referencing torque or the circle constant τ = 2π, but the simplest phrasing — 'letter after sigma' — is a dependable shortcut to fill those three squares. It’s a small, classic clue that warms my puzzle-loving heart whenever it appears.
