Crossword solvers have a language all their own. Spend a little time on puzzle blogs or forums and you will see people talking about Naticks, revealers, and crosswordese as if everyone knows what they mean. This glossary explains 40 of the most useful terms, grouped by topic, so you can follow the conversation and understand how puzzles are built.

Grid and Structure Terms

1. Grid

The pattern of white and black squares that makes up the puzzle. American daily grids are commonly 15x15, while Sunday puzzles are often 21x21.

2. Square (or Cell)

A single box in the grid that holds one letter, or occasionally more in special puzzles.

3. Black Square (or Block)

A shaded square that separates answers. Black squares are not filled in.

4. Across

Answers that run horizontally, from left to right.

5. Down

Answers that run vertically, from top to bottom.

6. Entry

Any answer written into the grid.

7. Cross (or Crossing)

The point where an across and a down answer share a square. Using crosses is one of the most important solving techniques.

8. Symmetry

The arrangement of black squares so the grid looks the same when rotated 180 degrees. Most American puzzles follow rotational symmetry.

9. Checked Letter

A letter that belongs to two answers. In American grids nearly every letter is checked; in British cryptic grids, many are unchecked.

10. Unches

Short for unchecked letters, meaning squares that belong to only one answer. The term is common among cryptic solvers.

11. Corner

One of the four sections of a grid. Solvers often describe a puzzle by saying a particular corner was the last to fall.

12. Section

A region of the grid connected to the rest by only a few squares. Tightly closed sections can be hard to break into.

13. Stack

Two or more long answers placed directly on top of each other or side by side, often seen in themeless puzzles.

Theme Terms

14. Theme

A unifying idea that connects several long answers, such as a shared pun, hidden word, or wordplay trick.

15. Theme Entries

The answers that carry the theme, usually the longest in the grid.

16. Revealer

A theme entry, often near the bottom of the grid, that explains what the other theme answers have in common.

17. Themeless

A puzzle with no theme, focusing instead on lively vocabulary and challenging clues. Late-week puzzles are frequently themeless.

18. Rebus

A square that holds more than one letter, a word, or a symbol. Rebus puzzles are a favourite way for setters to surprise solvers.

19. Meta

A puzzle with a hidden final answer that you must find after completing the grid, using clues contained in the solution.

20. Wordplay

Any trick involving the form of words, such as puns, anagrams, or added and removed letters.

Fill and Vocabulary Terms

21. Fill

All the non-theme answers in a grid. Good fill is fresh, familiar, and fun; weak fill relies on obscure or awkward entries.

22. Crosswordese

Short words that appear far more often in crosswords than in everyday life because their letters are convenient for constructors. Examples include ERNE, a sea eagle, and ESNE, an Anglo-Saxon labourer.

23. Partial

An answer that is a fragment of a phrase, usually clued with a blank, such as A LOT from a clue like "Thanks ___".

24. Abbreviation

An entry that is shortened, typically signalled in the clue by an abbreviation of its own or by words like "for short".

25. Natick

A square where two obscure answers cross, so that a solver who does not know either answer has no fair way to work out the letter. The term comes from a crossing involving the town of Natick, Massachusetts, discussed on a well-known crossword blog.

26. Plural of Convenience

An unusual plural used mainly to make a grid work, often viewed as a weakness in fill.

27. Seed Entry

A word or phrase a constructor chooses first and builds the rest of the grid around.

Clue Terms

28. Clue

The hint that leads to an answer.

29. Misdirection

Clue writing that leads you toward the wrong meaning. A clue's capitalised first word, for example, can disguise a proper noun.

30. Question Mark Clue

A clue ending in a question mark, signalling a pun or non-literal meaning.

31. Fill-in-the-Blank

A clue with a missing word, such as "Better late ___ never". These are often the easiest way into a grid.

32. Cross-Reference

A clue that points to another clue, for example "See 17-Across".

33. Definition

In cryptic crosswords, the part of the clue that plainly defines the answer, usually at the start or end.

34. Indicator

In cryptics, a word that signals what kind of wordplay to use, such as "mixed" for an anagram or "back" for a reversal.

35. Anagram

A word or phrase formed by rearranging the letters of another, a mainstay of cryptic clues.

36. Surface Reading

The apparent meaning of a cryptic clue as an ordinary sentence, which usually disguises its true structure.

People and Solving Terms

37. Constructor (or Setter)

The person who creates the puzzle. Americans usually say constructor, while British solvers say setter.

38. Editor

The person who reviews, adjusts, and approves puzzles and clues before publication.

39. Speed Solving

Solving a puzzle as quickly as possible, often against a timer or in tournaments.

40. DNF

Short for "did not finish", used by solvers to describe a puzzle they could not complete without help.

Using the Glossary

You do not need to memorise every term to enjoy crosswords, but knowing the vocabulary helps in two ways. First, it makes puzzle blogs, solving guides, and forums much easier to follow. Second, many of these words describe techniques: once you know what a revealer is, you will start looking for one; once you know about crosswordese, you will recognise those familiar short entries instantly.
