impregnated
含浸した
解説 Definition
impregnated は impregnate（しみ込ませる、含浸させる）の過去形・過去分詞です。液体や薬品などを素材の内部までしみ込ませた状態を表す、やや専門的な語です。
The past tense and past participle of impregnate, meaning caused a material to absorb or become thoroughly filled with a liquid, chemical, or other substance. It is often used technically in the passive construction “be impregnated with.”
覚え方のコツ Memory Tip
原形 impregnate「内部までしみ込ませる」に -d が付いた過去形・過去分詞で、語尾は /ɪd/ と発音します。この語義では be impregnated with oil/chemicals の形が典型です。表面を単に濡らすのでなく、布・木材・フィルターの内部を物質で満たす像で覚えます。
Learn impregnated through the technical pattern “material + was impregnated with + substance.” The base verb is impregnate, and adding -d gives both its past tense and past participle; because the base ends in /t/, the ending is pronounced /ɪd/. Imagine oil penetrating wood or carbon distributed throughout a filter, not liquid merely resting on the surface. This image distinguishes impregnated from wet or coated: the substance has entered and filled the material’s pores or internal structure.

その木材には水をはじくために油がしみ込ませてありました。

impregnated の語源・成り立ち Etymology
ラテン語のimpregnareに由来し、接頭辞in-（中へ）＋語根pregn（妊娠）＋接尾辞-ateで構成される。元来「子を抱かせる」意味が、内部を完全に満たすイメージに転じ、物質が隙間なく染み込む「含浸する」という意味に派生した。関連語にpregnantがある。
Impregnated is formed from impregnate plus the past-tense and participial ending -d. Impregnate ultimately comes from Late Latin impraegnare, built on praegnans, the source of pregnant, with a prefix conveying entry or causation. Its earliest sense concerned making pregnant. The idea of filling something internally later produced the technical material sense “to saturate or permeate thoroughly,” as with oil, resin, or chemicals.
