One way to hold this word: four corners marking out a flat piece of ground. Draw those corners on paper and you have a four-sided figure. Build them at full size, and stand a row of buildings along each of the four edges, and the same four corners now hold an open courtyard. Move your eyes from the ground up to the walls, and the word can point at the ring of buildings instead. One picture, three places to look.
From the word’s history
From Late Latin quadrangulum, through Old French and Middle English: quadr- (four) plus angulum (angle), literally a four-cornered thing. The four corners in the word are the four corners in every one of its uses.
來自晚期拉丁文 quadrangulum，經古法文和中古英文進入現代英文：quadr-（四）加 angulum（角），字面上就是「有四個角的東西」。字裡的那四個角，正是它每一個意思裡都看得到的四個角。
