“다정하다, 상냥하다, 친절하다, 착하다” 다정하다 = sweet and caring (usually between friends or lovers). It comes from 다(a lot) + 정 (love and care), but it can also mean acting/looking like this. 다정하게 걸어가는 두 사람. 상냥하다 = kind and nice in manners. 선생님은 늘 상냥하게 대답해 주신다. 친절하다 = be nice and helpful toward others. 이 가게의 점원들은 언제나 친절하다. 착하다 = be good and free of malice in character. 동생은 성격이 착해서 이제껏 누구와 싸운 적이 없다. 상냥하다 refers to the kind manners and style, and 친절하다 how helpful a person acts to others. 다정하다 usually describes how the relationship looks between two people (it can also describe an individual but less frequently). 착하다 refers to the underlying goodness of a person rather than how they are acting at the moment.
