cocksure
自信過剰な
解説 Definition
自分の判断や能力に対して過度に確信を持つこと。根拠を欠きながらうぬぼれた態度を示す状態です。
Cocksure means being extremely confident that you are right, often more confident than the situation justifies. The word usually has a negative feeling and suggests overconfidence.
覚え方のコツ Memory Tip
`sure` が「確信している」なので、`cocksure` はまず「確信の度合いが強すぎる語」と押さえると覚えやすいです。単なる `confident` が前向きな自信にも使えるのに対し、こちらは「根拠が薄いのに、絶対正しいと思い込んでいる」感じでかなり否定的。`overconfident` に近いですが、話し方や態度ににじむ“思い込みの強さ”を連想すると定着します。人の発言・判断・態度を批判的に述べる場面で出やすい語です。
The key part is `sure`, so think of someone who feels too sure. `Cocksure` is stronger and more negative than simply `confident`. It suggests a person who sounds certain even when they may not have good reasons. Link it with `overconfident` and with an attitude that feels annoying or arrogant.
