Mediums in which Korean rapper's describing a certain style (8)
I believe the answer is:
psychics
'mediums' is the definition.
(I've seen this before)
'korean rapper's describing a certain style' is the wordplay.
I cannot quite see how this works, but
'style' could be 'chic' (chic can mean elegance or style) and 'chic' is located in the answer.
This explanation may well be incorrect...
'in which' acts as a link.
Can you help me to learn more?
(Other definitions for psychics that I've seen before include "They claim to be in touch with the spirit world" , "They claim the ability to see the future" , "They claim clairvoyance" , "People with occult powers or extrasensory perception" , "Clairvoyants" .)
