What does 푹 mean? When and how to use it in with a word?

Answer

푹 is an onomatopoeic adverb associated with "deep" and "long".
To Koreans, the sound of 푹, (or lengthened to 푸욱 sometimes) evokes something deep and long.
- 푹 자다:  sleep soundly (deep, long sleep with no interruption).
- 칼로 푹 찌르다:  stab deeply with a knife.
- 푹 과 [고아]:  deep-simmer it for a long time (to cook even the bones).  고다: simmer for a long time.
