外面那層乾殼，還有把它弄掉
這一支完全是字面的：先有那層殼，再有把殼弄掉的動作。名詞和動詞是同一個字，講的是同一個東西的兩面。
noun · B2
The dry outer covering of a grain, seed, nut or ear of corn — the part you pull off, break open or throw away before you get to the part you eat.
外殼；穀皮
核心畫面
One way to hold this word: a husk is the dry layer between you and the good part. Green leaves around an ear of corn. The rough coat off a grain of rice. The thick fibre around a coconut. It is always outside, always dry, and always in the way. From that one picture the other uses follow easily. Taking that layer off is the verb. And when the good part inside has gone and only the dry layer is standing, that is a husk too — a building, a tree, or a person.
husk 可以想成「擋在你和好東西中間的那層乾皮」。玉米外面那幾層葉子、稻米碾下來的粗糠、椰子外面那層厚纖維，都是它…更多收起
husk 可以想成「擋在你和好東西中間的那層乾皮」。玉米外面那幾層葉子、稻米碾下來的粗糠、椰子外面那層厚纖維，都是它。三個特點每次都在：在外面、乾的、要去掉。有了這個畫面，另外兩個意思就順著走了。把那層弄掉，就是動詞。裡面的東西沒了、只剩那層還立著，也叫 husk——可能是一棟廠房、一棵樹，也可能是一個人。這只是串起三個意思的一個想法，不必當成每個用法的證據。From the word’s history
The packet's Wiktionary entry traces the word to Middle English huske, and offers two possible routes further back: an Old English word for a little covering or sheath, or a Middle Low German word for a little house or sheath. It marks both as uncertain. Either way the earlier meaning is a small covering, which is exactly the modern core.
來源把這個字追到中古英語的 huske，再往前給了兩條可能：一條接到古英語裡「小小的套子、殼」，另一條接到低地德語的「小房子、套子」。來源自己標明兩條都不確定。不過兩條的早期意思都是「小小的包覆物」，跟今天的核心畫面正好對得上。
Wiktionary entry for husk (etymology 1), supplied in this packet (source_ref kaikki:3f6f69a190036ae4:800399271:34360): From Middle English huske; perhaps from Old English *husuc / *hosuc (little covering, sheath); alternatively from Middle Low German hûs(e)ken (little house, sheath).

裡面沒了，只剩那層殼
把穀殼的畫面整個搬去講別的東西。剝完之後地上剩下的那層，就是這裡要講的狀態：外形還在，內容沒了。
noun · C1
What is left of something after everything useful or living inside it has gone or been used up — the dry, empty outside with nothing in it. It is often used of a person who has been worn down until little of the old self is left.
