The 점심 - Dim Sum Connection

The Korean word for lunch (점심) comes from the same Chinese characters as Dim Sum (點心 or 点心). In Cantonese it is pronounced dim sam, and in Mandarin it is pronounced dian xin. In Japanese they pronounce it as tenshin and it means "snack" . In Vietnamese it is diem tam and means "breakfast". Apparently the lunch meaning came through Eastern Chinese dialects, as in the Shanghai dialect ti xin, is often used for "lunch". In most dialects of Chinese it means "snack", "light refreshment" or "pastry". The word dates back to the Tang Dynasty (618 - 906 A.D.).
