Ignore area (6)
I believe the answer is:
region
'area' is the definition.
(I know that area can be written as region)
'ignore' is the wordplay.
'ignore' can be anagrammed to 'REGION'.
Though, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for region that I've seen before include "Area, location" , "Area, territory" , "Part of a country" , "Area, zone" , "Ignore (anag) - area" .)
