Start with broil: strong heat beating straight down onto food from close above. A broiler is whatever that heat has to do with — the hot bar at the top of the oven that makes it, or the young bird raised to go under it.
可以先想 broil 這個動作：很強的熱，從很近的上方直直打在食物上。加上 -er 之後，broiler 就成了「跟這把火有關的那一個」。它可能是製造那把火的機器，也就是烤箱上面那根發熱管；也可能是被送去那把火底下的那隻雞。同一個字尾，指的對象卻在兩邊。
From the word’s history
Broil + -er, where -er is the suffix that names the doer; for the chickens it works the other way and names the one the action is done to. That single split is exactly why the word covers both a part of a cooker and a farm bird.
字面是 broil 加 -er。-er 通常指「做這件事的那一個」，但用在雞身上時方向反過來，指「被這樣處理的那一個」。這個字尾的兩種方向，正好說明為什麼同一個字可以同時是烤箱裡的一區，也是農場裡的一隻雞。
