Simplified etymology

Quadrangle is formed from Latin quattuor “four” and angulus “corner, angle.” The related prefixes quadri- and quadru- also mean “four.”

Through Old French from Late Latin quadrangulum, "four-angled figure," formed from Latin quattuor, "four," + angulus, "angle." The architectural sense developed because an enclosed courtyard and its surrounding buildings often form a four-sided plan.
