Other forms: squares
A square has four straight sides of the same length and four right-angled corners. One tile on a bathroom floor, one of the sixty-four squares on a chessboard, the little box on a form you have to tick.
The town square is the open space in the middle of a town: flagstones, a fountain, pigeons, somewhere to buy coffee — the market square, Trafalgar Square. In maths the square of a number is that number times itself, so the square of five is twenty-five, and you square a number to get there. As an adjective it means square-shaped, and also honest and straight: a square deal, a square meal. You square up to a problem when you turn and face it, and you square accounts when you settle them. Old slang calls a dull, conventional person a square, and that one now sounds like a film from 1958.

Behind square is Latin quadrus, reached through ex and quadro: Vulgar Latin exquadra, then Old French esquarre, and English took it from there. Squad is the very same word arrived along a different road. Old English had no need of any of it and said fēowerecge: four-edged.
