Etymology: The noun "quad" is a clipping, shortened from longer English words rather than borrowed whole. Its deeper ancestor is the Latin "quattuor," meaning four, which also lies behind "quadri-" and "quadruple." The shortest route from that root runs through the many English words built on "quad-," and the clipped form took on several separate lives. Its meaning of a square area or a fourfold unit comes from that numerical root. The typography senses are a different story. In printing, a "quadrat" was a block of metal used to fill spaces between words or lines, and printers shortened it to "quad." Because the blank filler blocks were the same kind of thing, the abbreviation quietly took over the name, so a printer's "quad" is a spacer rather than anything four-sided. The keyboard command "quad" in computing comes from the verb sense of the word, so the three uses share a root but developed independently in printing, geometry and software.

Synonyms: quadrilateral, fourfold
