覚え方のコツ Memory Tip
exacerbate「問題などを悪化させる」の過去形・過去分詞で、語末の e にそのまま -d を付けて exacerbated となります。「新しい要因が既存の悪い状態をさらに深刻にする」のが核で、the delay exacerbated the problem や was exacerbated by lack of sleep の形が典型です。単に悪い bad より変化を強調します。
Connect exacerbated with the base verb exacerbate, “to make an already bad condition worse.” Since exacerbate ends in e, its past and past-participle form simply adds -d. Imagine a problem that already exists and then receives another harmful push: a delay exacerbated the problem, or stress was exacerbated by lack of sleep. This focus on increased severity distinguishes it from merely describing something as bad. In passive sentences, by often introduces the factor that caused the worsening.
例文

exacerbated の語源・成り立ち Etymology
ラテン語 exacerbare（ex-「完全に」+ acerbus「苦い、厳しい」）に由来。「苦さを極限まで高める→悪化させる」が原義。同根語に acerbic（辛辣な）、acerbity（厳しさ）がある。苦味が増すイメージで「状態が悪くなる」と覚えると定着しやすい。
Exacerbated is the past and past-participle form of exacerbate. Exacerbate comes from Latin exacerbāre, meaning “to irritate, provoke, or make harsh.” That verb is related to acerbus, “harsh, bitter, or unripe,” with ex- adding an intensifying force in this formation. The historical image of increasing harshness developed naturally into the modern meaning of making pain, conflict, difficulty, or another harmful condition more severe.
