"The conditions get better."
If someone remembers, the word '낫다' was introduced waaay at the beginning of the course with a collocation with 병 (illness, disease).
아이는 병이 나아요 - 'the child gets better' or 'the child recovers from the disease'.
Must admit it's rather confusing for a beginner-beginner. Need more exercises on 나다 and 낫다.
Is the following assumption correct ?
나아요 - present tense of 낫다 (improve, get better).
Past tense: 나았어요, 나았다 Type: independent verb
나요 - present tense of 나다 be, get, make)
Past tense: 났어요, 났다 Type: passive auxiliary verb (can act as independent or integral/suffix verb)
