| | The Straight Dope: Why are crossword puzzles symmetrical? (Site not responding. Last check: 2007-10-26) |
 | | Crossword puzzles are symmetrical mainly because (1) symmetrical puzzles appeal to their authors' neurotic love of order (have you ever talked to a crossword puzzle editor?), and (2) the word arrays that crossword puzzles are based on have always been symmetrical, dating back to ancient times, when they were thought to have mystical significance. |
 | | In these puzzles, which were supplied without diagrams, you were asked to construct some sort of symmetrical word array (usually a square or a diamond, but sometimes a star or other shape) on the basis of various clues. |
 | | These puzzles had in turn been suggested by two earlier gimmicks: the acrostic (if you solved all the clues the first and/or last letters of the solutions would spell out another word or words), and the good old word square (the words read the same horizontally or vertically). |
