Software Quote Puzzle
The crossword is the most common variety of word puzzle in the world. Modern crosswords normally take the form of a square grid of black and white squares; the aim is to fill the white squares with letters, forming words (or word phrases) reading across and down, by solving clues which yield the words. The black squares are used to separate words. Squares in which answers begin are usually numbered; the clues are then referred to by these numbers and a direction - for example, "1-Across" or "17-Down"; at the end of the clue the total number of letters is sometimes given for the convenience of the solver, dependent on the style of puzzle and country of publication.
Terminology
The creating of crosswords is called 'cruciverbalism' among its practitioners, who are likewise referred to as 'cruciverbalists'; the terms derive from the Latin for 'cross' and 'word'. Although the terms have existed for over a decade, non-cruciverbalists rarely use them, calling crossword creators simply 'constructors' or 'setters'.
The horizontal and vertical lines of white cells into which answers are written are commonly called 'entries' or simply 'answers'; the clues themselves are usually called just that, or sometimes 'definitions'. A freeware screensaver with 21 beer quotes
