このエントリでは foolish を、単なる日常的な「ばかな」よりも、思慮や分別を欠いたために賢明でない判断・行動を表す語として覚えます。ポイントは人の知能そのものより、decision, action, risk, mistake などの選択や振る舞いに批判を向けることです。unwise に近いが少し感情的で、stupid ほど露骨に能力を否定しない語感があります。
Start with "fool," then add "-ish," a common ending meaning "rather like that" or "having that quality." That makes "foolish" feel like "showing a fool's kind of thinking." It often goes with choices and actions, like "a foolish decision," more than with a person's whole ability.
例文

Making foolish decisions can lead to regret.
愚かな判断をすると後悔することになります。
He made a foolish mistake that cost him dearly.
彼は多くの代償を払う愚かな過ちを犯しました。
ばかな
(意味 2)解説 Definition
foolish は、考えが浅くてばかな、またはそんな行動・考えを表す形容詞です。日常会話では人だけでなく、a foolish mistake や a foolish idea のように失敗・判断・発言にもよく使います。相手を直接責める響きがあるので、使う場面には注意します。
Foolish describes someone, an action, or an idea that shows poor judgment or not enough careful thought. It is often used not only for people but also for things like mistakes, decisions, questions, and comments. The word usually sounds more critical than playful, so it can feel direct if you use it about a person.
覚え方のコツ Memory Tip
fool は「ばかな人」や「だます」という基本語で、そこに形容詞を作る -ish が付くと「ばかっぽい、ばかな性質を示す」と考えられます。childish や selfish と同じ -ish の形で覚えると定着しやすい語です。silly は軽いおどけた感じにも使えますが、foolish は判断や発言がよく考えられていないという批判が強めです。a foolish mistake, idea, question のような組み合わせで見かけます。
Think of fool as the basic word meaning a stupid person, and -ish as an ending that means "having that quality." So foolish means "like a fool" or "showing the nature of a fool." It can help to remember other -ish adjectives such as childish and selfish. Compared with silly, foolish often sounds more critical and is commonly used in phrases like a foolish mistake or a foolish idea.
例文

彼女は数字をよく確認しなかったので、ばかなミスをした。
I did not want to ask a foolish question in front of everyone.

foolish の語源・成り立ち Etymology
foolish は fool + -ish「〜っぽい」。fool は古フランス語 fol、さらにラテン語 follis「ふいご・空気袋」にさかのぼり、「中身がなく風でふくらむ人」から「愚かな人」へ意味が移った。関連語は fool, folly。
"Foolish" is formed from "fool" and the adjective ending "-ish," meaning "somewhat like." "Fool" came through Old French from Latin "follis," meaning "bellows" or "air bag." The sense seems to have shifted from something empty but puffed up to a person seen as silly or lacking good sense, and the same root appears in "folly."
