核心畫面
Picture a tomato you grew yourself: the seed went into your own soil, and the thing came up there. Every use of the word is that same picture with the patch of ground made bigger — a garden, then a town, then a country, then a football club's youth team. What stays constant is the claim: this came up here, it was not brought in.

想像一顆自己種的番茄：種子下在自家的土裡，東西也就從那裡長出來。這個字的每一個用法，都是同一張圖，只是把那塊地放大——先是菜園，再來是一座城市、一個國家，最後是球隊的青年隊。不變的是它在主張的那件事：這是從我們這裡長出來的，不是外面運進來的。From the word’s history
Simply home plus grown. Home traces back through Old English ham to a Germanic root for a dwelling place, and grown is the past participle of grow, so the compound says exactly what it looks like: grown at home.
就是 home ＋ grown。home 一路回溯到古英語 hām，再往上是日耳曼語表示「住處」的字根；grown 是 grow 的過去分詞。所以這個組合字面上說的就是它看起來的意思：在家裡長出來的。
