Adequate rent sought, ignoring outskirts (6)
I believe the answer is:
enough
'adequate' is the definition.
(I know that adequate can be written as enough)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for enough that I've seen before include "As much as desired" , "This is going no further!" , "` `A word to the wise is ......' '" , "As much as needed" , "satisfying" .)
