核心畫面
Picture a small British town with one street running through the middle of it. The bank, the baker, the chemist and two cafés are all on that street, and everybody walks down it at some point in the week. That one street is the high street.

high street 可以想成英國小鎮中間那條唯一的主街。銀行、麵包店、藥局、兩家咖啡店都開在這條街上，鎮上的人一個星期總會走上它幾次。那條街就是 high street。也因為鎮上的買賣幾乎都發生在這條街上，這個名字後來像是連「買賣這件事」本身也一起指了進去。From the word’s history
Wiktionary traces high street to Old English hēahstrǣt, a high road — high + street. The high here can be thought of as chief or main, the same high as in high road, rather than anything to do with height.
Wiktionary 把 high street 追到古英文 hēahstrǣt（高的路），也就是 high 加 street。這裡的 high 可以想成「主要的、幹線的」，跟 high road 是同一個用法，不是在講高度。
Wiktionary, entry “high street”: “From Middle English high strete … from Old English hēahstrǣt (‘high road’), equivalent to high + street.”

那條街代表的生意
借代的那一族：講的還是那條街，但重點已經從路面移到路上發生的買賣。
