Where Does Letter After Sigma Crossword Clue Show Up In Cryptics?

I get excited when simple phrases like "letter after sigma" turn up because they’re tiny logic puzzles inside the larger grid. Most often it simply points to 'tau' — the next Greek letter — or to the English letter T if the setter is using sigma to represent S and then asking you to take what follows. In cryptic mechanics that can be used as a straight definition (the clue defines TAU), as an instruction to place T somewhere (insertion or sequencing), or as part of a charade where you tack TAU onto another element.

When I’m solving, I look for other signals: does the surface suggest a Greek theme (so TAU fits), or is there an instruction word like 'after' that tells me to append one letter to another component? Sometimes the clue will deliberately blur the line to be mischievous — that’s when you need to test both TAU and T in the crossing letters. It’s a neat little nugget that reveals a setter’s mood, and when the crossings confirm it, I get a little thrill every time.

Lately I’ve been paying way too much attention to how setters hide tiny Greek alphabet jokes in cryptic clues, and the classic "letter after sigma" is a favourite little trick. In plain terms, sigma is followed by tau in the Greek alphabet, so the straightforward read is that the clue points to 'tau' (three letters) or sometimes just the letter 'T' if the puzzle is anglicising the sequence (sigma ~ S, next letter T). Where it shows up in cryptics depends on what the setter wants to do: it can be a straight definition ('Greek letter: letter after sigma' → TAU), a letter substitution indicator (use T), or part of wordplay where 'after' tells you ordering (put something after S or put TAU after another chunk).

I love examples because they make things click. A surface like “Greek mark after student meets exam” could intend STUD + T (student -> 'stu', exam -> 'test' truncated, etc.) but a cleaner one would be: “Narrow passage following Greek letter after sigma (4)” where the answer might be 'GATE' constructed as GA (Greek letter gamma abbrev) + TE (T after E?) — okay, that’s me flexing the idea, but real puzzles do this more cleanly: “Greek letter after sigma in church building (3)” → TAU (definition: Greek letter after sigma; surface: church building is a red herring or a double definition if the setter is playful with architectural terms). Setters often treat 'sigma' as either the Greek name or the English letter it commonly maps to, so watch for signals that choose between 'TAU' and 'T'.

Beyond the literal, there are trickier uses: cryptics sometimes need a single-letter insertion, so 'letter after sigma' might mean 'put the letter that follows S (i.e., T) into another word', or it might be clued by homophone/charade conventions if the setter wants to be fiendish — e.g., the clue could make you think of the Greek alphabet but actually needs the English next-letter. Regional style also matters: British cryptics are more fond of Greek-letter names used as definitions; American variety puzzles less so. Personally I adore spotting when a setter slips in Greek-letter wordplay because it feels like a wink between solver and setter — and it’s always satisfying to pin down whether the intended result is TAU or just the letter T.
