Every use of this word starts from one Latin word: rex, a king. From there it goes two ways — it stays a king (the plain noun, the title after a name, the state that brings a case in the king's name), and it travels sideways into the names of animals, where 'king' became a breeder's compliment to a coat.

這個字的所有用法都從同一個拉丁字出發：rex，國王。從這裡它走了兩條路。一條路上它一直是「王」：可以是羅馬的王本身，可以是刻在國王名字後面的稱號，也可以是用國王名義起訴的那一方。另一條路離開了王室，跑進動物的品種名裡——當年有人覺得那身毛好看得像王，就把這個字放進名字裡，久了就變成一種毛質的代稱。From the word’s history
English took rex straight from Latin rēx, 'king'; the breeders' use arrived separately in about 1920, from the Belgian rabbit breed castorrex, 'beaver king', named for fur that resembled a beaver's.
英文的 rex 直接借自拉丁文 rēx（國王）。動物品種那個用法是另一條路：最早是比利時一種毛像海狸的兔子品種 castorrex（海狸王），這個字大約在 1920 年代以這個意思進入英文。兩條路的源頭是同一個拉丁字，但進入英文的時間和管道不一樣。
