なるほど
naruhodo
Means 'I see' or 'That makes sense.' Used to show you follow someone's explanation. Casual to neutral, fine with friends or colleagues, but avoid using it toward someone clearly senior in a formal setting as it can sound evaluative.
Use when listening to a friend explain something, hearing a new idea, following a story, casual workplace chat
なるほど、そういうことか。
naruhodo, sō iu koto ka.
I see, so that's how it works.
