解説 Definition

Hyper は、過度に興奮した、非常に活発なという意味の形容詞です。日本語の「ハイパー」は「すごい」「超高性能な」という意味で使われることもありますが、英語では人や行動が落ち着きなく活発すぎる様子にもよく使います。

Informally, excessively excited, energetic, or active, often to the point of being restless or difficult to calm. It is commonly used of children, adults, or animals displaying unusually intense activity.

覚え方のコツ Memory Tip

ギリシャ語由来の hyper-「超えて、過度に」を独立した口語形容詞として使った語です。英語では「超高性能」というより、人や動物が興奮して落ち着かず、活動的すぎる状態を指すことが多い語です。get hyper、be hyper after sweets、a hyper dog のように、普段の活動量を越えてはしゃぐ場面で覚えます。

Connect hyper with the Greek element hyper-, meaning “over, beyond, or excessive,” as in hyperactive and hypertension. Used alone as an informal adjective, hyper usually describes a person or animal whose excitement and activity have gone beyond the normal level. Picture children becoming restless after a party or a dog jumping around when guests arrive. Common patterns are be hyper, get hyper, and become hyper. Unlike the Japanese promotional use of ハイパー for something extremely powerful or advanced, everyday English hyper often carries the idea of excessive energy and difficulty staying calm.

例文

The kids were Hyper after eating sweets.

子どもたちはお菓子を食べたあと、とても興奮していました。

He gets Hyper when he is nervous.

彼は緊張すると落ち着きがなくなります。

My dog becomes Hyper when guests arrive.

来客があると、うちの犬はとてもはしゃぎます。

hyper の語源・成り立ち Etymology

hyper はギリシャ語 hyper「上に、超えて」に由来する語で、「ふつうの程度を越える」が核の意味。だから口語で「興奮しすぎた」「テンションが高すぎる」という形容詞になる。関連語は hyperactivehypertension

Hyper comes from Greek hyper, meaning “over, above, beyond, or excessively.” English has long used hyper- as a combining form in learned and technical words, including hyperactive, hypertension, and hypersensitive, where it signals an unusually high degree or level. In informal modern usage, hyper became an independent adjective, partly as a shortening associated with hyperactive. It now commonly describes someone who is overexcited, unusually energetic, restless, or unable to settle down.
