Question

What is the meaning of 주의?
I see on instagram tags like #신남 주의, #사랑 주의,  #멋진 주의, #겁나 이쁨 주의

Answer

When it's separated with previous word with a space like in your examples, it means caution.
#겁나 이쁨 주의= #Caution: Super pretty

However, if it's merged with the previous word, it becomes -ism. 인상주의=impressionism
