故に

1. Origins, structure, and basic meaning

• Structure: Spelling: 故に. Reading: ゆえに. Core meaning: therefore; for that reason.
• Basic usage: Representative examples: この道は狭い。故に、大型車は通れない / 未経験であるが故に、思い切った提案ができた.

2. Common pitfalls and similar expressions

• Conclusion and reason
  • Standalone 故に links a conclusion to the preceding statement, while a construction such as であるが故に presents the preceding state as a reason. It is more literary and formal than ordinary conversation.
