門閥

1. Origins, structure, and basic meaning

• Structure: 門閥 (もんばつ) means lineage or family status carrying social influence.
• Basic usage: In a premodern society, family background shapes advancement; a historical-fiction character rises through ability instead.

2. Common pitfalls and similar expressions

• Inherited background controlling advancement and privilege deliberately not relied upon
  • In 門閥が出世を左右する, lineage is the force shaping the system; in 門閥に頼らない, it is a source of advantage the character refuses to use. Both contrast with individual ability.
