Food is central to Korean culture, and a few core words cover most situations. 밥 (bap) means both "rice" and "meal," 물 (mul) is water, and 김치 (gimchi) is the iconic fermented spicy cabbage served at virtually every Korean meal. Among Korea's most famous dishes, 비빔밥 (bibimbap) is mixed rice topped with vegetables, meat, an egg, and gochujang chili paste; 불고기 (bulgogi) is thinly sliced marinated grilled beef; 떡볶이 (tteokbokki) is chewy rice cakes stir-fried in spicy sauce and sold widely as street food; and 삼겹살 (samgyeopsal) is thick sliced pork belly typically grilled at the table in Korean barbecue restaurants. To compliment a meal, say 맛있어요 (masisseoyo), meaning "it's delicious." Before eating, guests say 잘 먹겠습니다 (jal meokgesseumnida) to thank the cook in advance, and after eating they say 잘 먹었습니다 (jal meogeosseumnida) to express thanks for the meal. Korea is also known for its drinks: 소주 (soju) is a clear distilled liquor typically around 16 to 20 percent alcohol by volume, while 막걸리 (makgeolli) is a traditional milky rice wine that is slightly sweet and gently carbonated.
Family relationships are reflected in Korean vocabulary, and the words for "older brother" and "older sister" change based on the speaker's gender. A female speaker calls an older brother 오빠 (oppa), which doubles as a term of affection for older males, while a male speaker says 형 (hyeong). Likewise, a female speaker calls an older sister 언니 (eonni), while a male speaker says 누나 (nuna). Koreans also use several colorful exclamations in daily speech: 대박 (daebak) means "awesome!" or "jackpot!" and is used to express amazement, 화이팅 (hwaiting) is a cheerful "fighting!" or "you can do it!" used to encourage others, and 아이고 (aigo) is an exclamation like "oh my!" or "oh dear!" used to vent surprise, frustration, or exhaustion.
Modern Korean culture has spread worldwide under the umbrella term 한류 (hallyu), or the "Korean Wave," which includes K-pop, K-dramas, and Korean cinema. Two iconic social spaces also define leisure: 노래방 (noraebang) is a private karaoke room where groups sing together, and 찜질방 (jjimjilbang) is a public bathhouse and sauna complex where people bathe, sweat in themed hot rooms, and often nap overnight. For visitors, a few key travel phrases round out the basics: 얼마예요? (eolmayeyo?) asks "how much is it?", 화장실이 어디예요? (hwajangsiri eodiyeyo?) asks "where is the bathroom?", 이해 못 해요 (ihae mot haeyo) or 모르겠어요 (moreugesseoyo) means "I don't understand," and 천천히 말해 주세요 (cheoncheonhi malhae juseyo) politely asks the speaker to "please speak slowly."
