牙齒上的嵌體
同一個動作換到牙齒上：洞就是挖好的凹，嵌體就是照它做的那一塊。
noun · B2
A hard filling for a decayed tooth, usually made of gold or ceramic, shaped outside the mouth to fit the hole exactly and then cemented into place.
（補牙的）嵌體
核心畫面
Inlay can be pictured as making room and then filling it exactly. A space is cut into a surface, a piece of some other material is shaped to that space, and it goes in until the two are level. Nothing stands up above the surface; run your hand across and you feel one thing, not two. That is the pattern on a wooden box, and it is also what a dentist does to a tooth: clean out the hollow, make a piece that matches it, set it in.
inlay 可以想成「先挖出位置，再剛好填滿」：在表面上挖一塊凹，把另一種材料照那個形狀做好，放進去，直到兩邊齊平。…更多收起
inlay 可以想成「先挖出位置，再剛好填滿」：在表面上挖一塊凹，把另一種材料照那個形狀做好，放進去，直到兩邊齊平。沒有東西凸出來，手摸過去只感覺到一個面，不是兩層。木盒上的花紋是這樣做出來的，牙醫做嵌體也是這樣做的——把蛀掉的地方清乾淨，做一塊剛好合的，再放進去。From the word’s history
The source analyses inlay as in- + lay, literally 'to lay in'. The modern meaning has not moved far from that: the material goes into the surface rather than onto it.
字典把 inlay 拆成 in-（進去）加 lay（放、鋪），字面就是「放進去」。今天的意思離那個字面沒有走遠：材料是進到表面裡，而不是留在表面上。
Wiktionary (kaikki extract kaikki:3f6f69a190036ae4:1253461737:9430), inlay: 'From in- + lay.'
From the picture
盒子裡的那張紙
這一條連得比較鬆：紙是放在盒子「裡面」的，但它並沒有嵌進任何表面，也沒有齊平。當成記憶上的連結就好，不要把它當成歷史上的衍生。
