涵蓋得廣：性質，還有被涵蓋的那一大群
這一組把「退一步」當成好事。看得廣，就能說得廣；而且你這時看到的那一大片人或東西，本身也拿同一個字來叫。
noun · C1
The quality of covering most cases instead of only one — how widely an idea, rule, or method holds true.
普遍性；通用程度
核心畫面
Think of generality as the result of back. Up close you see one worker, one case, one classroom. Step back and you stop seeing any single one; you see the whole crowd and what is true of most of it. The step back gives you three things at once: the quality of covering a wide area, the crowd you are now looking at, and whatever you can say from that distance — which is broad, and has no detail left in it.
「generality」可以想成「往後退一步之後看到的東西」。湊近看，你看到的是一個工人、一個案例、一間教室。往後退…更多收起
「generality」可以想成「往後退一步之後看到的東西」。湊近看，你看到的是一個工人、一個案例、一間教室。往後退，單獨的那一個就消失了，剩下一大片，還有對這一大片大致成立的事。general 是「一般的、大多數的」，加上 -ity 就變成「那個性質、那個狀態」。這一退同時給你三樣東西：一是「涵蓋得很廣」這個性質；二是你現在看到的那一大群人或東西；三是站在這個距離講得出來的話——很廣，但細節都沒了。同一個動作，好處和壞處都在裡面：廣度是它的價值，沒有細節是它的代價。From the word’s history
From Middle English generalite, from Anglo-Norman and Middle French generalité, from general + -ité, with influence from Latin generālitās. By surface analysis it is simply general + -ity: the quality of being general.
依據來源記載，這個字來自中古英語 generalite，再往前是盎格魯-諾曼語和中古法語的 generalité，也受到拉丁文 generālitās 影響。從字面拆開就是 general 加上 -ity，也就是「一般這個性質」，剛好就是這個字的核心。
Wiktionary entry “generality” (evidence packet etymology_text): Middle English generalite < Anglo-Norman / Middle French generalité < general + -ité; also influenced by Latin generālitās; by surface analysis general + -ity.
Two branches
講得太廣的那句話
同樣是退一步，這裡退過頭了。距離讓你講得廣，也讓細節全部消失；只剩廣度的話，就成了空話。所以這一條的語氣跟另一組相反：那邊的「廣」是優點，這邊的「廣」是抱怨。
