解説 Definition

根拠のない自信や傲慢な態度。自分の能力を過度に評価する性質。

Cockiness is an attitude of being too confident and too sure of yourself. It usually has a negative meaning and suggests that someone seems arrogant or disrespectful. The word is informal and is used for behavior rather than simple self-confidence.

覚え方のコツ Memory Tip

cocky を知っていれば、cockiness はその性質を表す -ness 付きで「生意気さ」。confident が前向きな自信、overconfident が「自信過剰」、arrogance が硬めの「傲慢」なのに対し、cockiness は『実力はまだ十分でないのに、やけに自信満々で鼻につく』軽薄さを帯びる語。a cocky smile, youthful cockiness のように、表情や態度の“イキり感”と結びつけて覚えると残りやすい。

If `cocky` means overly self-confident, `cockiness` is that attitude as a noun. It is not the same as healthy confidence; it usually suggests someone acting too sure of themselves. Phrases like `a cocky smile` make the feeling easy to remember.

例文

His cockiness led him to underestimate his competitors.

彼は生意気な自信のせいで競争相手を甘く見た。

The team's cockiness before the match proved to be their downfall.

試合前のチームの傲慢さが彼らの敗因となった。

She spoke with such cockiness that nobody took her seriously.

彼女はあまりにも尊大な話し方をしたので、誰も彼女を真剣に受け止めなかった。

cockiness の語源・成り立ち Etymology

cockiness は cocky + -ness で、cocky は古英語 cocc 由来の cock「おんどり」から来た。胸を張って歩く雄鶏の姿がそのまま「生意気な自信」に変わった語で、cock や cockerel を思うと意味が腑に落ちる。

Cockiness comes from cocky plus the noun ending -ness. Cocky comes from cock, the old word for a rooster, from Old English cocc. The link is the proud, strutting way a rooster carries itself. That image gave the word its sense of bold, overconfident attitude. Related words include cock and cockerel.
