Is "Naruhodo desu ne" Correct Keigo? The Line Between Youth Slang and Business Japanese
「なるほど (Naruhodo)」 is a wonderfully expressive word. It's the perfect response when something clicks into place, meaning "I see," "That makes sense," or "Aha!". You'll hear it often in casual conversations among friends and colleagues. It shows that you're not just hearing the words, but truly understanding the logic behind them.
Because it's so useful, many learners and even younger native speakers try to make it polite by simply adding 「ですね (desu ne)」 to the end, resulting in 「なるほどですね (naruhodo desu ne)」. While this might sound polite, it is generally considered incorrect Keigo and can be seen as inappropriate when speaking to a superior or a client.
This guide will explain why 「なるほどですね」 is problematic and provide you with the correct, respectful alternatives to use in formal and business settings.
1. Why "Naruhodo" Can Be Disrespectful
The word 「なるほど」 originally comes from 「なる (naru - to become)」 and 「ほど (hodo - degree)」. In essence, when you say it, you are confirming that the other person's explanation has brought you to a state of understanding. This contains a subtle nuance that you are evaluating or appraising their explanation.
Just like saying 「さすがですね (sasuga desu ne)」, it can carry an unintended tone of "speaking from above" (上から目線 - ue kara mesen). You are essentially stamping their explanation with your approval. While this is fine with peers, it can sound arrogant when a junior says it to a senior.
Simply adding 「ですね」 doesn't change this underlying nuance. It's like putting a polite sticker on an informal word.
2. The Correct and Respectful Alternatives
So, what should you say when your boss explains something and you want to show you've understood? Here are some excellent, safe, and respectful options.
The Best All-Purpose Phrase:
左様でございますか。(さようでございますか)
(Sayō de gozaimasu ka.)
"Is that so?" / "I see." (This is a very polite and formal equivalent of そうですか - sō desu ka).
To Show You've Learned Something:
勉強になります。
(Benkyō ni narimasu.)
"I'm learning a lot." / "That's very informative."
To Show Agreement:
おっしゃる通りです。
(Ossharu tōri desu.)
"It is just as you say." (Very respectful way to agree).
To Show You Understand and Consent:
かしこまりました。
(Kashikomarimashita.)
"I understand." / "Certainly." (Used when receiving instructions).
3. When Is "Naruhodo" Okay?
「なるほど」 is perfectly fine and very common in casual situations. You can use it freely with:
- Friends and family
- Colleagues of the same or junior rank
- In any informal setting where Keigo is not required
Conclusion
While language is always evolving and phrases like 「なるほどですね」 are becoming more common, it's crucial for a learner to understand the proper rules of Keigo, especially for business Japanese. Using it with a superior could leave a negative impression, marking you as someone who doesn't understand formal etiquette.
By saving 「なるほど」 for your friends and using respectful alternatives like 「左様でございますか」 or 「勉強になります」 with your superiors, you demonstrate a high level of both linguistic and cultural competence.
