## Etymologies

Japanese suudoku, contraction of suu(ji wa) doku(shin ni kagiru), the numbers must be unmarried (that is, occur singly).
(American Heritage® Dictionary of the English Language, Fourth Edition)
Japanese 数独 (sūdoku), numbers singly (Wiktionary)

• It's taken me this long to find out what the word comes from. It's a contraction suu-doku "single digits" of the phrase suuzi-wa dokusin-ni kagiru "the digits are restricted to single" ("digit-TOPIC single-TO restrict" – with dokusin meaning "single" as in "unmarried", a little oddly).

It began as an American puzzle called Number Place; a Japanese company later issued it as Sudoku, a trade mark in Japan, where it is generically known as nanpure, a contraction of the English name.
