  • 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(とお)りです or 承知(しょうち)しました are safer responses.
