gamsahamnida
Gamsahamnida is a common Korean phrase used to express gratitude. It is considered a polite and formal way to say "thank you" in the Korean language. The phrase is composed of two parts: "gamsa" which means "gratitude" or "thanks," and "hamnida" which is a formal verb ending indicating an action is being performed. Therefore, gamsahamnida literally translates to "I am giving thanks" or "I express gratitude."
While gamsahamnida is widely used, there are other ways to express thanks in Korean, varying in formality.
