Suffering from severe cold, Greek character encounters doctor (4)
I believe the answer is:
numb
'suffering from severe cold greek' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
'character encounters doctor' is the wordplay.
'character' becomes 'nu' (nu is a kind of character).
'encounters' says to put letters next to each other.
'doctor' becomes 'MB' (abbreviation for Bachelor of Medicine).
'nu'+'mb'='NUMB'
Can you help me to learn more?
(Other definitions for numb that I've seen before include "Without sensation" , "Insensate" , "Deprived of feeling" , "Stinks" , "Lacking feeling" .)
