覚え方のコツ Memory Tip
harmonics は harmonic の複数形で、語末の -s は通常 /s/ と発音します。harmony「調和」と結びつけ、基音に対して整数倍などの整った関係をもつ複数の周波数成分を想像します。produce clear harmonics、measure harmonics の組み合わせで覚えると実用的です。
Harmonics is the plural of harmonic; the final -s is normally pronounced /s/. Connect the word with harmony: several frequency components are related to a fundamental frequency in an orderly way, often as whole-number multiples. On a guitar, clear harmonics can sound light and bell-like, while engineers measure harmonics in electrical or audio signals. Useful combinations include produce harmonics, measure harmonics, and unwanted harmonics. The plural is natural when several frequency components are being discussed, while a harmonic identifies one component.
例文

The engineer measured the harmonics in the signal.
技術者は信号に含まれる高調波を測定しました。

harmonics の語源・成り立ち Etymology
harmonics はギリシャ語 harmonikos「調和のとれた」が語源で、harmonia「結びつき・調和」にさかのぼります。音や波が基音と整った比で結びつくため「高調波」を表します。関連語に harmony、harmonize。
Harmonics is the plural of harmonic, which entered English through Latin harmonicus from Greek harmonikos, meaning “harmonious” or “skilled in music.” That adjective derives from harmonia, “joining, agreement, or harmony.” In scientific and musical use, harmonic came to denote a frequency related to a fundamental frequency by an orderly numerical ratio. Adding the regular plural ending -s produces harmonics, referring to two or more such components.
