Usage of うん
"うん" is an informal and casual way to say "yes" or "okay" in Japanese. It is commonly used in everyday conversations among friends, family, or people of the same age or lower status. It is less formal than "はい" and conveys a relaxed, friendly tone.
Common contexts
You will often hear "うん" as a quick affirmative response to questions or requests, especially in spoken language. It can also express agreement or understanding.
Collocations and patterns

- うん、そうだね: "Yeah, that's right" – agreeing with someone's opinion.
- うん、いいよ: "Okay, that's fine" – giving permission or approval.
Register and nuance
Because "うん" is informal, avoid using it in formal situations, such as business meetings or with strangers. Instead, use "はい" for polite affirmation.
Common learner mistake
Learners sometimes confuse "うん" with "えん" or other sounds. Remember that "うん" is a short, nasal affirmative sound, often accompanied by a nod. It is not used to express hesitation or uncertainty.
