If you’re a fan of K-pop or K-dramas, you may have heard idols or characters saying the word “sunbae” (선배) when referring to another idol or an older, more experienced character. The English translation of the Korean word “sunbae” is “senior,” but it’s also used to refer to any older person who has more experience in a given field. In this article, we’ll explain the meaning of “sunbae” and how to use it respectfully, with exclusive insights from a Korean language and culture educator. We’ll also cover the different levels of Korean formality and other Korean honorific titles to help you better understand the culture.

What does “sunbae” mean in Korean?

Korean language and culture educator The Bad Korean Teacher says “sunbae” is used to address anyone older or more experienced in school, work, or a specific field. It literally translates to “senior.” For example, you can refer to a teacher, supervisor, mentor, or colleague who has worked longer than you as “sunbae.”

1. 
   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, says Korean Language and Culture Educator The Bad Korean Teacher. The term shows respect and sometimes implies a mentorship, 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.
   • In professional or academic settings, people use “sunbae” to refer to colleagues who started before them, no matter how old they are.
   • “Sunbae” is appropriate to use in formal settings or with a supervisor or teacher because it’s more professional than family honorifics–like “oppa” or “unnie”–that are also used with close friends.
   • Unlike age-based honorifics, “sunbae” emphasizes experience and seniority in a specific context. However, culturally, most people would not call someone younger “sunbae” unless they have proven themselves exceptional and worthy of respect. For example, someone might be your “sunbae” at work, but not in casual settings.
   • How to pronounce “sunbae”: It’s a 2-syllable word where the “sun” sounds like “suhn” and “bae” sounds like “beh.”
   • How to write “sunbae”: Write “sunbae” in Korean as “선배.” In romanized letters, spell it as “sunbae,” but you may also see it written as “seonbae” or “sun-bae.”

How to Use “Sunbae” (선배)

Download Article

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. The Bad Korean Teacher says that it’s also a good general term for anyone in a higher grade than you at school. 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.”

   Say “sunbae-nim” for an even more polite version of “sunbae.” Adding “-nim” to “sunbae” makes the term more formal and sets the tone for the rest of the conversations to be in formal Korean. 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.

   • “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. 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)

Download Article

1. 
   “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 university or business settings. 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.

   • “Hubae” is basically the opposite of “sunbae,” so age isn’t as important as experience.
   • The suffix “-nim” is less likely to be used here, as most people talk to their “hubae” in a casual tone.
   • For example, “Hubae, you did a great job on your project,” or “I’m so proud of you, hubae-nim.”

Levels of Korean Formality

Download Article

1. 
   Korean has different speech levels that show respect and relationship. While there are technically 7 levels, modern Koreans mainly use 3–4 in everyday life, and the others are mostly outdated or only seen in historical contexts. The most commonly used form is 해요체 (polite “-요” form), which works in most situations. In more formal settings, Koreans use 하십시오체 (formal “-습니다” form). When speaking casually with friends, family, or younger people, 해체 (casual form) is used. 해라체 is mostly used in writing, such as news or instructions.

   • Haeche (해체): Casual and informal speech used with close friends, siblings, and younger people; no politeness markers; example ending “-아 / -어.”
   • Haeyoche (해요체): Polite and most commonly used speech in daily life; used with strangers, coworkers, and people you don’t know well; safest default; example ending “-요.”
   • Hasipsioche (하십시오체): Formal and very polite speech used in professional settings, customer service, announcements, and when speaking to elders; example endings “-습니다 / -습니까.”
   • Haerache (해라체): Plain style mostly used in writing, such as news, books, or instructions; occasionally used in speech between close people of equal status; not commonly used by beginners in conversation
   • Simple rule: If you’re unsure what to use, stick with the “-요” form (해요체), and you will almost always be safe.

Importance of Age in Korean Culture

1. 
   1
   Koreans use age to decide how formal their speech should be. When they first meet, Koreans often ask each other, “What year are you?”, which essentially is asking, “How old are you?” This helps them figure out how to speak and act appropriately toward one another. 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 show respect. Some examples include bowing when greeting, setting the table, or pouring 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 1st of the year after their birth. At the same time, some Korean people who visit abroad sometimes use the international age, which is the same as people use in the U.S.

   • On June 28, 2023, South Korea officially adopted the international age system for legal and administrative use. However, traditional age-counting is still sometimes used informally in everyday conversation

Other Korean Honorific Titles

1. 
   1
   Use the appropriate age- and gender-specific titles to show respect in Korean. In Korean, many common honorific titles reflect the speaker's gender and the relationship to the person they’re speaking about. For example, “hyung” is commonly used by men and boys to refer to other males. Here are a few other honorific titles and nicknames used in South Korean culture:

   • Oppa (오빠): Women and girls use “oppa” to refer to an older male they are close to. It translates to “older brother.”
   • Hyung (형): Men and boys use “hyung” to refer to or address older males they’re close with, such as an older brother, cousin, or friend.
   • Unnie (언니): Women and girls use it to refer to an older female they are close with. It also translates as “older sister.”
   • Noona (누나): Men and boys use it to refer to an older female they are close to. It translates to “older sister.”
   • Orabeoni (오라버니): “Orabeoni” is another way for women and girls to refer to an older brother. It’s considered old-fashioned and is most often seen in historical K-dramas.
   • Abeoji (아버지): This is the formal way to say “father.” Koreans would more commonly use appa (아빠), which means “dad.”
   • Eomeoni (어머니): This is the formal way to say “mother” in Korean. More commonly, Koreans would call their mother eomma (엄마), which means “mom.”
   • Dongsaeng (동생): Males and females use it to refer to a younger person they are close with. It translates to “younger sibling.”
   • Halabuji (할아버지): This is translated as “grandfather” and is a respectful way to address a man older than 70. This is a generic term that’s not necessarily used for your biological grandfather.
   • Halmeoni (할머니): This is translated as “grandmother” and is a respectful way to address a woman older than 70. This is a generic term that’s not necessarily used for your biological grandmother.
   • Chingu (친구): “Chingu” means “friend.” Use it to refer to someone who is the same age as you.

   Add “ssi” (씨) or “nim” (님) to the end of a name to show more respect. In Korean, the suffixes “ssi” and “nim” are used in a similar way to Mr. and Ms. in English. These suffixes are gender-neutral and appropriate for anyone to use. Place them at the end of the full name. For example, Park Yun-ho-ssi in Korean would be Mr. Yun-ho Park in English.

   • Place the “ssi” after the given name for a casual title that shows respect. For example, “Yun-ho-ssi” in Korean would be “Mr. Yun-ho” in English.
   • The suffix “nim” is slightly more formal than “ssi” and appropriate for more formal or professional settings.
   • Koreans list their surname first and the given name second.
3. 
   3
   Add “ah” or “ya” to the end of someone’s name to show close relationships. When calling out to someone casually, add an “ah” (아) suffix to the person’s name if it ends in a consonant or a “ya” (야) suffix if it ends in a vowel. It doesn’t matter what gender the person is, only what letter their name ends with.

   • For example, if you have a friend named Hyejin, you might call her Hyejin-ah. If you have a friend named Junseo, you might call him Junseo-ya.
