日曆上的那一段，和落在人身上
把天上的那一對搬到日曆上，再從日曆搬到人身上；名字一路沒變，只是指的東西越來越具體。
noun · B1
The third sign of the zodiac, shown as a pair of twins. It covers people born between about May 22 and June 21, and some people believe it shapes what those people are like.

Think of two figures standing side by side, so alike that you name them as one thing. That pair is drawn in the sky, printed as the symbol of the sign, and finally hung on a person born in those weeks. The word never really stops meaning the twins; it only changes what it is pointing at.

可以想成兩個人並排站著，像到你乾脆把他們當成一個東西來叫。這一對先是畫在天上——兩條星線，兩顆亮星；接著被印成星座的符號；最後貼在某個在那幾週出生的人身上。這個字其實一直都在說「那一對雙胞胎」，變的只是它指向哪裡：天上的星、日曆上的一段日子，還是坐在你旁邊的那個人。From the word’s history
Borrowed from Latin geminī, the plural of geminus (twin), itself a calque of Ancient Greek Didumoi; the pair are Castor and Pollux, whose names the constellation's two brightest stars still carry.
來自拉丁文 geminī，是 geminus（雙胞胎）的複數，再往前是古希臘文 Δίδυμοι 的仿譯。那一對就是 Castor 和 Pollux 兄弟，天上最亮的兩顆星至今仍用他們的名字——所以「兩個並排的人」不是後人加的比喻，而是這個字本來的意思。
