Endlessly enjoy severe area (8)
I believe the answer is:
district
'area' is the definition.
(I've seen this before)
'endlessly enjoy severe' is the wordplay.
'endlessly' means to remove the last letter.
'enjoy' becomes 'dig' (to dig can mean to appreciate or 'get').
'severe' becomes 'strict' (I've seen this before).
'dig' with its last letter taken away is 'di'.
'di'+'strict'='DISTRICT'
(Other definitions for district that I've seen before include "A quarter" , "Locality" , "Precinct, section" , "Area of town/country" , "Area of town or country" .)
