How to Say Crossword in Different Languages
Crosswords in other languages examples; 5/29/2013
Wikipedia: crosswords in other languages, cryptics in other languages; crossword orthography


cluelessstraight or quick
usually simple definitions; maybe anagrams; rules/conventions;
themes (category; quotes; puns; commemoration; rebus); indirect?
e.g., UK cryptics. "clues are puzzles in themselves. A typical clue contains a definition at the beginning or end of the clue, and wordplay, which describes the word indicated by the definition, and which may not parse logically, but should be grammatical."
double-clue lists
choose between straight or cryptic clues
Fill In The ___
an answer that any player will get easily, e.g., 'Lincoln's nickname' in three letters


black whitewhite cells
or lights
checked, keyed or crossed
"A white cell that is part of two entries (both Across and Down);
a white cell that is part of only one entry is called unchecked, unkeyed or uncrossed." (uncommon in US puzzles)
3Dblack squares
or darks, blanks, blocks, shaded squares
entries or answers
"horizontal and vertical lines of white cells into which answers are written"

Grid Size, Shape, Style

american gridAmerican-style (US) grid
solid areas of white squares; every letter checked; symmetry (180-degree rotational)
Wikipedia: New York Times (NYT)
Why are crossword puzzles symmetric?
crossword for morons 1 squaregrid sizes
mini: 5x5, e.g., NYT
weekday: usually 15x15
weekend: 21x21, 23x23
jumbo: 27x27
foreign: rectangular
custom shapes, e.g., maps, tree, heart, etc.
british gridBritish-style (UK) grid
lattice-like structure; more shaded and unchecked squares; symmetry (180-degree rotational)
Wikipedia: Cryptic
french gridFrance, Italy
crosswords are smaller than English-language crosswords, and not necessarily square
they need not be symmetric and two-letter words are allowed
Italian crosswords are usually oblong and larger than French ones
japanese gridJapan
shaded cells may not share a side; the corner squares must be white
one syllable (typically katakana) rather than one letter is entered into each white cell
swedish gridSweden
no clue numbers; shaded cells are often replaced by boxes with clues (arrows, photos)
crisscrossfree-form crosswords (criss-cross or vocabulary puzzles)
simple, non symmetric designs. Grids forming shapes other than squares are also occasionally used.
barredbarred crosswords
use bold lines between squares (instead of shaded squares) to separate answers
essentially four small puzzles joined in the center by a few letters. Each quadrant needs to be solved separately. example
circular designs
circular crosswordanswers entered either radially or in concentric circles
codewordcipher crosswords / codewords
"clues for each white cell of the grid - an integer from 1 to 26 inclusive is printed in the corner of each. The objective, as any other crossword, is to determine the proper letter for each cell; in a cipher crossword, the 26 numbers serve as a cipher for those letters: cells that share matching numbers are filled with matching letters, and no two numbers stand for the same letter. All resultant entries must be valid words. Usually, at least one number's letter is given at the outset. English-language cipher crosswords are nearly always pangrammatic." example
diagramlessdiagramless, skeleton
"the grid offers overall dimensions, but the locations of most of the clue numbers and shaded squares are unspecified. A solver must deduce not only the answers to individual clues, but how to fit together partially built-up clumps of answers into larger clumps with properly-set shaded squares."
crusadexfill-in, crusadex
"a grid and the full list of words to be entered in that grid, but does not give explicit clues for where each word goes. The challenge is figuring out how to integrate the list of words together within the grid so that all intersections of words are valid."

Difficulty, Themes

already solved crosswords"commuter" crossword
usually "quick and easy" clues Mon-Fri; often < NYT Mon

type of puzzle in which a square can be filled in with a sequence of letters, or a digit or picture/symbol
we'll see examples during Solving: Discover the Theme
alphabet soupholoalphabetic
denoting a grid in which all of the letters of the alphabet appear. Sometimes "pangram" is used synonymously -- though this may be incorrect. "A holoalphabetic crossword without an ulterior purpose is like a can of Campbell's alphabet soup ('oh, let me see if they are all there'). What it is not is a 'pangram' -- an overused misnomer of crossword bloggers. A pangram is a sentence that uses every letter of the alphabet. A holoalphabetic crossword allows the construction of a pangram." ~NYT Crossword in Gothic
