窩在蛋上的鳥
這一組就是字面本身，也是其他意思的來源。畫面裡只有一隻不肯離巢的母雞。
adjective · B2
Of a female bird, especially a hen: wanting to lay eggs and then sit on them and stay there, keeping them warm until the young birds break out.
抱窩的
核心畫面
Think of a hen on a nest. She has settled onto her eggs and she is not getting up — not for food, not for you. She is silent, up, turned inward, and she will peck the hand that comes near. Every use of broody can be seen growing out of that one bird. Sit on your own thoughts the way she sits on her eggs, and you are broody in the quiet, closed-off sense. Feel that same protective pull toward a baby of your own, and you are broody in the other. Even a low grey sky can look as if it is sitting on something it will not show you.

可以想成一隻趴在窩上的母雞。她窩在蛋上就是不肯起來：餵食不起來，你伸手也不起來。她安安靜靜、羽毛蓬著、整個縮進自己裡面，誰靠近就啄誰。broody 的每一個意思，都可以看成從這隻母雞長出來的。你像她孵蛋那樣孵著自己的心事，就是那個「悶著不講話」的 broody。心裡湧上想要一個孩子的念頭，就是另一個 broody。連低低壓著的灰雲，看起來也像在孵著什麼不給你看的東西。From the word’s history
Wiktionary traces broody to Old English brōdiġ, formed from brood plus -y, with German brütig as a cousin. A brood is a sitting of eggs or the young that come from it, so the bird sense is the oldest layer and the human senses sit on top of it.
Wiktionary 把 broody 追到古英語的 brōdiġ，是 brood（一窩雛鳥／孵蛋）加上 -y，德語的 brütig 是它的表親。brood 本來就是「一窩蛋或雛鳥」，所以鳥的意思是最底下那一層，講人的用法都疊在上面。

adjective · B2

悶著心事
