覚え方のコツ Memory Tip
accelerate「加速する・速める」に -ed が付いた過去分詞由来の形容詞で、「通常より速められた状態」を示す。語末の e を取って -ed を加え、発音は /əkˈseləreɪtɪd/。accelerated speed は速度、an accelerated schedule は日程の進み方が速い、と物理・比喩の両場面を結ぶ。
Accelerated comes from accelerate, meaning “make or become faster,” plus -ed. In spelling, the final e of accelerate is replaced when -ed is added; the ending is pronounced as an extra syllable, /ɪd/. Connect two uses: accelerated movement involves a physical increase in speed, while an accelerated schedule compresses work into less time. In both cases, the rate has been raised above an earlier or normal level. The related noun accelerator, such as a car’s accelerator, provides a concrete reminder of the central idea of increasing speed.

accelerated の語源・成り立ち Etymology
accelerated は accelerate＋-ed。語源はラテン語 accelerare にさかのぼり、ad-「〜へ」＋celer「速い」から成るので、「速さを与えられた」がそのまま「加速された」の意味になる。関連語は celerity, accelerator。
Accelerated is the past-participle and adjectival form of accelerate, formed with -ed. Accelerate comes from Latin accelerāre, “to hasten,” built from ad-, “toward,” and celer, “swift.” Through assimilation, ad- appears as ac- before the following consonant. The original structure therefore carries the idea of moving toward greater speed. English relatives include acceleration and accelerator, while celerity preserves the Latin root celer more visibly and means “swiftness.”
