1.
I see; indeed
Expression of understanding or agreement with what someone has said.
2.
certainly; truly
Acknowledging that something is as described.
A conversational response showing understanding or agreement with what someone has said. Very common in daily conversation.
Usage
- Typically used at the start of a response: なるほど、そうですか
- Shows the speaker has understood or been convinced
- Often repeated while listening (like English "uh-huh" or "I see")
Watch out
Using なるほど toward superiors or in formal settings can sound condescending, as it implies you are evaluating and judging what the other person said. In business, おっしゃる通りです or 承知しました are safer responses.
