The literal translation of “sunbae” is “senior.” Both men and women use “sunbae” to address or refer to someone who is older or more senior in school, work, or a specific field. The term shows respect and sometimes implies a mentorship between the two, with the older or more experienced person offering guidance to the younger or less experienced person. For example, a K-pop trainee might refer to an idol who has already debuted as “sunbae” because they have more experience. The idol may also offer advice or assistance to help the trainee perform better.^{[1]

1
Use “sunbae” to address a more experienced person. Use this term to refer to someone with more experience than you. Because it implies mentorship, it’s appropriate to use it when asking for help or advice from a more experienced person. However, it’s not strictly tied to age like other honorifics. The more experienced person may be younger than you. It’s also a good general term for anyone in a higher grade than you at school.^{[3]

Research source} A few examples of ways to use “sunbae”:
- “Sunbae, could you please review my work?”
- “Do you have a second to help me find my classroom, sunbae?”
- Remember, even though you may be owed respect as a “sunbae,” you’re still expected to show respect with other age-related honorifics, like “hyung” or “unnie.”
2
Say “sunbae-nim” for an even more polite version of “sunbae.” Adding “-nim” to “sunbae” makes the term more formal and respectful. Use it when you first meet someone more experienced than you to show them respect and acknowledge you don’t know each other well enough to drop the formality.^{[4]

Research source}
- “It’s very nice to meet you, sunbae-nim.”
- “Sunbae-nim, thank you for such valuable advice.”
3
Add “sunbae” or “sunbae-nim” to the end of a person’s name. While people often simply call a more experienced person “sunbae” or “sunbae-nim” it’s also used as a suffix to a person’s name.^{[5]

Research source} For example, “Yoon-gi sunbae” or “Ji-won sunbae-nim.” This can make the term feel more personal without affecting the formality.
- “Yoon-gi sunbae helped me with my homework and I got the highest marks in my class!”
- “Thank you for all your help with my project, Ji-won sunbae-nim.”

“Sunbae” (선배) vs. “Hubae” (후배)

“Hubae” is the opposite of “sunbae” and refers to a less experienced person. “Hubae” translates as “junior,” and older people use it to refer to younger people in a university setting or in business. They also use it to refer to someone with less experience in a field. Even though this term means you are less experienced, it doesn’t carry a negative meaning.^{[6]

- “Hubae” is basically the opposite of “sunbae,” so age isn’t as important as experience.
- The suffix “-nim” can be used with “hubae” for a more formal title, just as with “sunbae.”
- For example, “Hubae, you did a great job on your project,” or “I’m so proud of you, hubae-nim.”

Korean speech uses 7 different layers of formality. Koreans use 4 of these layers most often, and consider the others outdated. For formal speech, they use hasipsioche. Haerache, a plain yet formal way of speaking, is the most commonly used level. Haeyoche is an informal but polite way to speak with strangers, colleagues, and those of higher rank or older age. When speaking with friends or younger people, Koreans use haeche. Here are descriptions of all 7 of the speech levels, from the most casual to the most formal:
- Haeche (해체): Haeche is the most casual and informal level of speech that’s only used with siblings, close friends, relatives, and younger people.
- Haeyoche (해요체): Haeyoche is an informal but polite way of speaking that Koreans use in their everyday life.
- Haerache (해라체): This is a plain style that’s still formal. It’s commonly used in newspaper or magazine writing. It’s also how close friends or family members of a similar age speak to each other.
- Hageche (하게체): Haerache is a slightly outdated type of speech, mostly used by older people, that’s used with those of a similar or lower rank.
- Haoche (하오체): Haoche is a formal level of speech used with those who have a similar or lower social status. It’s more commonly used in historical dramas than in real life.
- Hasipsioche (하십시오체): Hasipsioche is 1 step down from hasoseoche and often used in public speeches, business, and by those in the service industry. It’s also the type of speech Koreans commonly use with elders, strangers, and those of higher rank.
- Hasoseoche (하소서체): Hasoseoche is the most formal and polite way of speaking. Koreans use it when speaking to a king, queen, or high official. It was mostly used in the past but is commonly seen in historical dramas.^{[15]

Koreans use age to decide how formal their speech should be. When they first meet, Koreans often ask each other, “How old are you?” This helps them figure out how to speak and act appropriately toward one another.^{[16]

Research source} For example:
- Older people take on more responsibility and act as leaders for younger people. They’re also usually expected to buy meals. They may ask younger people to perform tasks for them.
- Younger people are expected to bow deeply, set the table, or pour drinks for older people.

Before 2023, Korean age was based on the number of new years plus 1. In South Korea, people used to have two different ages. They were considered 1 year old when they were born. Then, they turned 2 years old on January 1 of the year after they were born. At the same time, they used international age, which is the same as people use in the US.^{[17]
