What does 감사합니다 mean?

감사합니다 (gamsahamnida) is the formal way to say "thank you" in Korean and the version most learners are taught first. Built from 감사 (gamsa, "gratitude" — Sino-Korean 感謝) plus 하다 (to do) plus the formal 합니다 ending, it is the safest "thank you" for any context: shops, restaurants, formal greetings, business meetings, broadcasting. The polite-informal version 고마워요 (gomawoyo) and casual 고마워 (gomawo) come from a different root verb 고맙다 — both mean the same thing but signal closeness. K-pop idols thanking fans use 감사합니다 (formal) almost universally; among friends 고마워 dominates. When unsure, default to 감사합니다.

Literal meaning
I do gratitude / I thank
Origin
감사 (Sino-Korean 感謝, "gratitude") + 하다 (to do) + formal speech-level ending. The -합니다 ending marks 합쇼체 (formal speech).
