말 잘하고 싶을 때 가장 중요한 비밀

What does “yuchanghada” mean in Korean?

유창하다 is the word learners want for themselves: 한국어를 유창하게 하다, “to speak Korean fluently.” Its hanja, 流暢, mean “flowing” and “unobstructed,” so the picture is speech running smoothly rather than catching. It belongs almost entirely to language ability, and it is more formal than what Koreans actually say about a friend, which is just 한국어 잘한다.

The speaker takes the word apart on purpose. Everyone tells him they want to be 유창한, he says, but the thing that matters more is being 유해하지 않은 — not harmful. One syllable apart, opposite priorities. His practical advice follows: say good things to the person in front of you and your own life changes shape.
