撐住形狀的內部骨架
這一組最貼近核心畫面：東西本身太軟或太空，所以先做一副硬架子放在裡面。

A frame that you build first and then cover with clay, wax or other soft material, so that the model has something firm inside to hold its shape.
骨架；支架
核心畫面
You can picture an armature as the hard thing inside that holds a soft or moving thing together. A lump of clay cannot stand up by itself, so the maker puts a wire frame inside it first. A 3D character is only a surface, so the puts a chain of bones inside it. A motor needs one part that carries the wire and turns, so the wire is wound onto a core. In each case the armature is not the thing you look at. It is the part underneath that lets the thing hold its shape or do its work.

「armature」可以想成藏在裡面、撐住一切的那副硬架子。一團黏土自己站不起來，所以要先折一副鐵絲骨架，再把土包上去。一個 3D 角色只是一層殼，所以要在裡面放一串骨頭，它才會動。一台馬達需要一塊能纏線又能轉的鐵芯，那塊就是它的 armature。三個地方的共同畫面是：你看到的不是它，但少了它，東西就垮掉或動不了。From the word’s history
Wiktionary gives the source as Middle French armature, from Latin armatura, meaning armour, and notes that armor and armure are doublets of it. Armour is a hard shell built to hold and protect a body, and that picture of a firm supporting structure is what stayed in the word after the fighting sense faded.
依 Wiktionary 的說明，armature 來自中古法文 armature，再往上是拉丁文 armātūra（盔甲），和 armor、armure 同源。盔甲是一副撐住身體、保護身體的硬殼。打仗的意思後來淡掉了，但「一副硬的支撐結構」這個畫面留了下來，正好對上今天的雕塑骨架和馬達鐵芯。

機器裡會轉的那一塊
從「裡面那塊硬東西」再走一步：它不只撐著線圈，還帶著線圈一起轉，成為機器出力的地方。

The part inside an electric motor or generator that turns. It is a metal core with wire wound around it, and its turning is what makes the machine give out movement or electricity.
