👀 Layer A: Visual Guide (直感理解)
📝 Quick Summary (まとめ)
「なぜ？」と聞かれたときに、理由(りゆう)を答える表現です。「～だからです」という意味です。
Use “Kara” to state the reason (“Because…”). It usually comes at the end of the reason clause. When answering “Why?”, end with “Kara desu”.
Connector: [Reason] から、[Result]。
Answer: [Reason] からです。
🔍 Layer B: Deepening (深掘り)
💡 Raya’s Hack (攻略法)
日本語は「理由が先」！
英語では “I study because I have a test” (結果→理由) ですが、日本語は逆です。
“Test ga aru kara, benkyou shimasu.” (理由→結果)
常に「理由」を先に言うクセをつけましょう！
Japanese syntax is “Reason First”. Always put the reason clause with “Kara” BEFORE the result clause. “Reason KARA, Result.”
🚧 Joy’s Mistake (よくある間違い)
Scene: Joy explains why he is late.
Joy: 「寝坊しました。だから 遅れました。」
(Nebou shimashita. Dakara okuremashita.)
⚠️ A bit childish/blunt.
Why?
「だから (Dakara)」を文の頭に使うと、少しぶっきらぼう（乱暴）に聞こえることがあります。
一つの文につなげて「寝坊しましたから、遅れました」と言う方がスマートです。
Starting a sentence with “Dakara” (Therefore/So) can sound blunt or argumentative. It’s smoother to connect the sentences with “Kara”. “Nebou shimashita KARA, okuremashita.”
