覚え方のコツ Memory Tip
hydro はギリシャ語由来の hydro-「水」を核にし、名詞では hydroelectric power を縮めた「水力発電」を表します。hydro power、hydro energy、hydro project のまとまりで、川やダムによる発電を連想しましょう。Hydro と大文字なら電力会社などの名称の一部である可能性もあります。
Use hydro- as the memory anchor: it comes from the Greek word for water and appears in many water-related terms. As a noun, hydro often shortens hydroelectric power or hydroelectricity, so picture a river or dam supplying electricity. Learn the combinations hydro power, hydro energy, and a hydro project. In some regions, hydro may also refer informally to the electricity supply or utility. A capital H can signal that Hydro belongs to an organization’s or project’s name, although ordinary references to the energy source are normally lowercase.

hydro の語源・成り立ち Etymology
hydro はギリシャ語 hydor「水」に由来する語で、水に関するものを表す連結形 hydro- として広く使われます。そこから「水力発電」や「水治療法」を略して hydro と呼ぶようになり、「水」が中心意味だと分かると派生語も覚えやすいです。関連語に hydrogen, hydraulic があります。
Hydro ultimately comes from Greek hydōr, “water,” through the combining form hydro-, used in words concerning water. The independent noun developed largely by shortening longer terms such as hydroelectric power and hydroelectricity. Its modern energy sense therefore refers to electricity generated through moving or falling water. The capitalized form Hydro is also used in the names of some electric utilities and projects, extending the same association with water-generated power.
