ルール
A single dash can introduce an explanation or emphasis at the end of a sentence, like a colon. A pair of dashes sets off extra information in the middle.
ダッシュ1つは文末でコロンのように説明や強調を導き、ダッシュ2つは文中の付加情報を区切る。
✔ 正しい文: The result surprised everyone—even the researchers.
✘ 誤った文: The result surprised—everyone even the researchers.
→ 直し方: Place the dash after the complete sentence "The result surprised everyone".
コツ: A single dash works like a colon: what comes before it must be a complete sentence.
