妄言

1. Origins, structure, and basic meaning

• Structure: 妄言 is read as ぼうげん and is a noun for a baseless, reckless, or absurd statement, expressed with strong disapproval.
• Basic usage: Use 妄言に惑わされる for being misled by it and 妄言を繰り返す for repeatedly making such claims.

2. Common pitfalls and similar expressions

• Strong negative judgment
  • It does more than neutrally mark a statement as incorrect; it criticizes the statement and the judgment behind it as reckless or absurd.
• Lack of basis and repetition
  • 根拠のない explicitly denies supporting grounds, while 繰り返す presents repeated production of such claims.
