   • Explanation: Using only から removes the emphasis. からこそ stresses the importance of having family as the key reason.
2. Incorrect Form with な-adjectives or Nouns
   • Incorrect: 静かなからこそ、集中できる。
   • Correct: 静かだからこそ、集中できる。
   • Explanation: だ must be added after な-adjectives and nouns before からこそ.

Learning Strategies

• Mnemonic Device: Remember that こそ adds emphasis, like underlining or bolding text. Think of からこそ as highlighting the reason.
• Practice Pairing: Pair からこそ with reasons you want to emphasize in daily life to become comfortable with its usage.
• Watch for だ: Always include だ after nouns and な-adjectives before からこそ.
