'quadrangle' originates from Latin, specifically the word 'quadrangulum,' where 'quadri-' meant 'four' and 'angulus' meant 'angle.'

'quadrangulum' transformed into the Old French word 'quadrangle,' and eventually became the modern English word 'quadrangle' through Middle English.

Initially, it meant 'a four-cornered figure,' but over time it evolved into its current meaning of 'a four-sided area, especially one surrounded by buildings.'
