弁論

1. Origins, structure, and basic meaning

• Structure: 弁論 is read as べんろん and functions as a noun or with する for presenting a reasoned position before an audience, either as oratory or as an argument.
• Basic usage: Mark the topic with について in 環境問題について弁論する, and use 彼女の弁論 for the argument being evaluated.

2. Common pitfalls and similar expressions

• Speech and argumentative content
  • A contest foregrounds the speech performance, while an evaluation of evidence and persuasiveness foregrounds the argument.
• Basis of persuasiveness
  • 根拠が明確 says that clear supporting grounds made it persuasive, not merely that it was delivered loudly.
