覚え方のコツ Memory Tip
pregnant を知っていると芯がつかみやすい語。『中に何かをしっかり抱え込む』イメージで見ると、impregnating は「表面に少し付ける」のではなく「内部までしみ込ませて満たす」感覚で覚えやすい。材料・工業では impregnated paper, resin impregnating のように、紙や木材に液体・樹脂を含ませる場面でよく出る。coating が表面を覆うだけなのに対し、impregnating は中まで入れる処理。-ing 形なので『含浸すること／含浸中の』の両方に注意。
Use the image of liquid going deep inside a material, not just sitting on top. `Impregnating` in technical writing often appears with wood, paper, fabric, oil, resin, or waterproofing. That helps you separate it from `coating`, which usually stays on the surface.

impregnating の語源・成り立ち Etymology
impregnatingはラテン語impregnareに由来し、in-「中へ」+pregnare「身ごもらせる」と分けられます。そこから「内部まで満たす」が生まれ、含浸の意味にも広がりました。pregnantやpregnancyが同じ根です。
Impregnating comes from Latin impregnare, built from in- "into" and a root related to being pregnant or made full. It first referred to making someone or something pregnant, and later widened to mean filling something deeply throughout. That is how it developed the sense of soaking or saturating a material.
