迷信

1. Origins, structure, and basic meaning

• Structure: 迷信 (めいしん) combines delusion 迷 and belief 信 to denote superstition.
• Basic usage: 迷信 is a belief or notion accepted without rational grounds.

2. Common pitfalls and similar expressions

• Belief rather than rumor
  • It is not merely an unverified rumor; the predicate after 迷信を shows whether the belief is accepted, rejected, or discussed.
