覚え方のコツ Memory Tip
powered は power に -ed を付けた過去分詞で、形容詞として「動力で動く」を表します。語末 /r/ の後なので -ed は /d/ と発音します。be powered by electricity の by は動力源を示し、solar-powered lamp のように「動力源＋powered」で複合形容詞を作れると覚えましょう。
Build powered from power plus -ed and picture energy being supplied to make a device work. The most useful pattern is “be powered by,” followed by the energy source: powered by electricity, powered by a battery, or powered by wind. Before a noun, combine the source with powered using a hyphen, as in a solar-powered lamp or battery-powered toy. The -ed ending is pronounced /d/ after the voiced final sound of power. This meaning concerns operating energy, not the separate sense of political influence or personal authority.

We saw a solar-powered lamp in the garden.
庭で太陽光で動くランプを見ました。

powered の語源・成り立ち Etymology
ラテン語 potere（できる）から古フランス語 poeir を経て英語 power に。語根は「能力・力」を意味し、-ed で「動力を備えた」の形容詞に。関連語: powerful（強力な）、empower（権限を与える）。「できる力」が原義で、そこから機械の動力の意味にも広がった。
Power entered English through Anglo-French and Old French forms ultimately related to Latin posse, “to be able.” The word first referred broadly to ability, strength, or authority and later developed technical senses involving energy and the capacity to operate machinery. Powered is the regular past participle of the verb power. As an adjective, it means supplied with power, especially from a named energy source.
