真的武器：放的地方、整套裝備、做的地方
這一組都還在核心畫面裡，只是鏡頭停在不同的位置：房間本身、架上的東西，或把東西做出來的工坊。
noun · B2
A room or building where weapons and armour are kept, for example in a castle, an army base, or a museum.
軍械庫
核心畫面
Picture a room where the weapons are kept: rows of them on shelves, each in its place, waiting for the moment someone needs one. Reach in, take what the job needs, put it back. That one room is the whole word. Sometimes the attention is on the room, sometimes on the things inside it, sometimes on the workshop that made them — and sometimes the weapons on the shelf are not weapons at all, but the skills a person can reach for.

可以想成一個房間：武器一排排放在架上，每一件都有自己的位置，等著有人需要的時候取用。伸手拿一件出來，用完再放回去。整個字就是這一個畫面。有時候鏡頭對著房間，有時候對著裡面的東西，有時候對著把它們做出來的工坊。而有時候架上的那些「武器」根本不是武器，而是一個人隨時拿得出來的本事。From the word’s history
Wiktionary traces armoury through Middle English armerie and Anglo-Norman armurrie to armure ('arms, armour') plus the ending -ie, so the word began as 'the whole business of arms' rather than as one room. That breadth is why it still covers the store, the collection and the workshop at once.
資料把 armoury 追到中古英語 armerie，再往前是盎格魯-諾曼語 armurrie，由 armure（武器、盔甲）加字尾 -ie 組成。它一開始指的是「跟武器有關的那一整套事情」，而不是單一個房間。這正好說明它為什麼同時能指庫房、整批裝備，還有製造的工坊。
Wiktionary entry supplied in evidence packet (source_ref kaikki:3f6f69a190036ae4:1167959181): "From Middle English armerie, armurie, armorye, from Anglo-Norman armurrie, from armure ('arms, armor') + -ie ('-y'). By surface analysis, armour + -y."

比喻：手邊可以拿出來用的本事
同一個房間，架上換成本事、方法和資料。需要哪一樣就伸手拿哪一樣，這是一個教學上的聯想，不是說這個意思比較晚出現。
noun · C1
All the skills, methods, facts or tools that a person or group has ready to use in order to get something done.
可用的本事、手段
