No wonder it's cold with 道理で〜わけだ
Grammar Explanation: Logical conclusion with 〜わけだ
It’s December, three days before the Winter Cup, and the weather report has warned of a major cold wave with snow. As the basketball team heads to practice, snow starts to fall.
- 生徒Ⓐ:
- 「今日は積もるって話だよ」
- “They say it's going to pile up today.”
- 生徒Ⓑ:
- 「道理で寒いわけだ」
- “No wonder it's so cold.”
Key Points
- わけだ presents a statement as making sense given known facts. Here the known fact is the snow, and the statement it explains is 寒い.
- 道理で means “that’s why” or “no wonder”. It often comes before わけだ when a speaker suddenly understands the reason for something they already noticed.
- The cold isn’t new information. She’d felt it already. What’s new is the reason, so the line works as a realization, not a prediction.
- 寒い is an い-adjective, so it attaches to わけだ directly. A noun or な-adjective would take な first: 雪なわけだ, 静かなわけだ.
- 積もる means for snow to pile up on the ground.
- って is casual という, and 〜って話だ passes on something heard: “they say…”. The first student is likely repeating the forecast.
- よ offers this as news to her teammate.
