Directions a worried medic follows in one area (7)
I believe the answer is:
endemic
'one area' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'directions a worried medic follows' is the wordplay.
'directions' becomes 'en' (east and north).
'a worried' indicates anagramming the letters (worry can mean to interfere with or disturb).
'follows' is a charade indicator (letters next to each other).
'medic' with letters rearranged gives 'demic'.
'en'+'demic'='ENDEMIC'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for endemic that I've seen before include "Men dice in way commonly found in country or place" , "Belonging to a particular area" , "Local (of disease)" , "Native to a certain area" , "Confined to a particular area" .)
