覚え方のコツ Memory Tip
insect が分かれば前半はそのまま「虫」。後半の -cidal は suicidal や homicidal などにも出る「殺す性質の」という形で覚えると、insecticidal は「虫を殺す力をもつ」と自然に取れる。名詞 insecticide が「殺虫剤」、形容詞 insecticidal が「殺虫性の」なので品詞差に注意。insecticidal spray, insecticidal soap のように、薬剤や成分の効き目を説明する場面でよく出る。
Start with `insect`, then notice `-cidal`, which appears in words about killing, like `homicidal`. That makes `insecticidal` easy to store as “having the power to kill insects.” Also keep the pair together: `insecticide` is the thing, while `insecticidal` describes its effect.
例文

殺虫性の特性は作物を害虫から保護する。

insecticidal の語源・成り立ち Etymology
insecticidal は insect＋-icidal に分かれ、insect はラテン語 insectum「切り込みのある虫」、-icidal は caedere「殺す・切る」に由来します。つまり原義は『虫を殺す性質の』で、体の節が切れ目のように見える虫を殺す語だと分かります。関連語は homicide, pesticide です。
Insecticidal is made from insect and -icidal. Insect comes from Latin insectum, meaning something "cut into," referring to the segmented body of an insect, while -icidal comes from Latin caedere, "to kill." The word was formed to mean having the power to kill insects. Related English words with the same root include homicide and pesticide.
