Detailed Explanation

• わけ (wake) means "reason" or "conclusion drawn from reasoning".

• ～わけがない is stronger, showing impossibility based on logical reasoning or evidence. Example:
• 彼が遅れるはずがない。
  • He shouldn't be late (but there's a slight chance).
• 彼が遅れるわけがない。
  • There's no way he would be late (absolutely impossible).

6. Common Mistakes and Tips

Error Analysis

  • Tip: Remember that ～わけがない is a strong denial, while ～ないわけではない means "it's not that I don't..."

Learning Strategies

• Mnemonic Device: Think of わけ as "wake"—as in waking up to reality. There's no "waking" to this reality because it's impossible.
