覚え方のコツ Memory Tip
contaminated は contaminate「汚染する」に -ed を付けた過去形・過去分詞で、語末の -ed は /ɪd/ と発音します。be contaminated や contaminated water・food・soil の形で、有害物質や細菌などが混じって安全でなくなった状態を表すと覚えます。単なる dirty より健康・環境上の危険を強く示します。
Start with the base verb contaminate, “to make something impure or unsafe,” and add -ed to form contaminated. Because contaminate ends in a /t/ sound, the ending is pronounced /ɪd/: contaminate becomes contaminated. Learn it in common combinations such as contaminated water, contaminated food, and a contaminated area, or after be in the passive: the water was contaminated. Unlike the broad word dirty, contaminated usually suggests that an unwanted substance, organism, or form of pollution creates a health, safety, or environmental risk.
例文

Do not eat contaminated food.
汚染された食べ物を食べないでください。
They closed the contaminated area.

contaminated の語源・成り立ち Etymology
ラテン語 contaminare(汚す・混ぜる)から。con-(共に)+ tangere(触れる)の語根 tag-/tam- に由来し、「接触して汚れが移る」が原義。関連語は contact(接触)、contagious(伝染性の)。触れることで不純物が広がるイメージが、現代の「汚染された」という意味に直結している。
Contaminated is the past tense and past participle of contaminate, formed regularly by adding -ed. Contaminate comes from Latin contaminare, “to defile or corrupt by contact or mixture,” related to contact through a root concerning touch. The historical image is of impurity spreading when things come into contact or become mixed. Modern uses retain that idea when chemicals, microorganisms, radiation, or other harmful matter enter water, food, soil, or an enclosed area.
