23 Essential K-Drama Words You Need to Know


Whether you’re a new or long-term K-drama fan, you need to know some essential Korean terms to better understand your favorite dramas. Even with subtitles, some terms don’t have direct translations into other languages and are most often just spelled out phonetically by the subtitlers or skipped over. Learn the following essential K-drama terms and you’ll soon sound like a Hallyu expert!


aegyo (EH-GYO) — Term that is used for the act of making a cute face and trying to act cute and adorable. For some reason, this seems to be a sought-after skill or personality trait by some drama men in the women they date!


aigoo (I-E-GO) — An expression of exasperation or frustration much like “Seriously?!” or “My goodness!” 

ajumma (AH-JOO-MAH) Generic word for “lady” or “woman” but has the connotation of being an older woman, possibly with children. You wouldn’t use this term for an obviously young women in her 20s or female students without greatly offending them.



ajussi (AH-JUH-SHEE)  Generic term for man or mister.” Just like “ajumma,” this term usually refers to an older man and wouldn’t be used on young men or male students (unless it’s a child calling the person).

chaebol (JEH-BOHR) — Heir (son or daughter) of a wealthy elite family who runs a national or international conglomerate business. There seems to be a ton of these people in Korea, if you were to believe K-dramas, and they’re all very good-looking and moody!

Some of our favorite drama chaebols include Ji Sung in ‘Kill Me, Heal Me,’ Choi Jin Hyuk and Lee Min Ho in ‘Heirs’ and So Ji Sub in ‘Master’s Sun


Chosun Dynasty (JO-SUN, sometimes written as Joseon Dynasty) Era in Korean history from 1392 to 1897 when many famous kings ruled and many evil family members tried to kill them. Most Korean historical dramas take place during this period, and many time-travel dramas involve traveling to or from (or back and forth) from this era to modern times.

daebak (DEH-BOK) — An expression of amazement or surprise that could be equated to “Wow” or “No way!” Drama characters usually lower their voice an octave when saying this word!

dong-seng (DOHNG-SENG) — “Younger brother.” This term can be used to express a close relationship with someone younger even if that person is not biologically related.

Fighting! (be sure to pronounce the T very strongly as in FIE-TING!) — A standalone word that is usually said very loudly while accompanied by a held-up fist, this word is used to encourage someone to do well before they face a tough situation or go into a lion’s den.

Gyung-bae! (GYUNG-BEH) — This word is a prerequisite for people to say before drinking alcohol at an after-hours drink-fest. It means “Cheers!” If you don’t say it before you down a shot of soju in a K-drama, it’s usually because you’re all alone and feeling sorry for yourself that you don’t have anyone to make a toast with!

heol (HURRR— An expression of surprise much like “daebak” but more along the lines of “OMG.” It’s also recommended that you deepen your voice for maximum effect when saying this word.

hoobae (WHO-BEH) A term to refer to someone younger than you who attended the same school but graduated after you. It also can be used to refer to someone who is hired later than you at your work. In Korean dramas, a lot of hazing comes with the territory of being the “hoobae.” You’re always stuck having to pay for coffee or doing other menial tasks for your “sunbae.”


hyung (make sure to pronounce both the H and Y and rhyme with sung— A term that means “older brother” when a younger boy or man is referring to another boy or man who is older. It can be used for anyone that is a close friend and doesn’t necessarily mean that you’re biologically related.


jjang (JONG with a hard J sound) — A term that means “the best” or “the greatest.” 

K-drama — Contraction of “Korean” and “drama” that only the truest K-drama fans use. Dont ever be caught saying Korean drama.


K-pop — Contraction of “Korean and “pop” that only true fans use to refer to a type of music that often involves a group of Korean men or women dancing in perfect synchronicity to a catchy tune that won’t leave your brain. As with K-drama, don’t be caught saying “Korean pop”!

kimchi (KIM-CHEE) — The national food of Korea that is universally eaten and beloved by all Korean people so much so that they devote entire dramas to the worship of this pickled or fermented cabbage. Although cabbage kimchi is the most common, the Korean people have turned pickling and fermenting of almost every type of vegetable into an art form.

noona (NU-NAH) The term for “older sister” that a boy or man calls a girl or woman who is older (the term used by females calling older females is “unnie”). But the term is often used by younger men to refer to an older woman that they like. “Noona romances” are a common storyline in K-dramas, and for some inexplicable reason, three years or eight years older seem to be the magic numbers for the “acceptable” age gap between a young man and a “noona.

oppa (OH-PA) — The term for “older brother” by girls or women referring to a male who is older. The term is used by women to refer to any friend or man who is a few years older, especially by the “third wheel” in a Korean drama who wants to get close to or steal a man away from another woman.

ramen (RAH-MEN) — The ubiquitous instant noodles that everybody in K-dramas eats so deliciously!

sageuk (SAH-GUK)  A Korean historical drama, usually set in the Chosun Dynasty, when the people spoke in a type of Korean thats hard for even Korean people to understand. In most sageuks, theres usually a king or crown prince who is trying to keep from being overthrown.

Some of our favorite sageuks include ‘The King’s Face’ (top) and ‘Secret Door

sunbae (SUN-BEH) — A term to refer to someone older who attended the same school but graduated ahead of you. Its a term of respect that everyone who graduated after you from the same school (hoobae) needs to call you. But being a sunbae in Korean dramas carries the burden of being asked for favors, jobs or money.


unnie (UN-NEE) — The term for “older sister” that a girl or woman calls someone older. This term is used to refer to someone older who may not necessarily be biologically related to show a close relationship.
