Eve gathers new clan in isolated area (7)
I believe the answer is:
enclave
'isolated area' is the definition.
(I've seen this in another clue)
'eve gathers new clan' is the wordplay.
'gathers' indicates putting letters inside.
'new' indicates anagramming the letters.
'clan' is an anagram of 'ncla'.
'eve' enclosing 'ncla' is 'ENCLAVE'.
'in' acts as a link.
(Other definitions for enclave that I've seen before include "Piece of territory within another country" , "Valence for small territory enclosed in foreign state" , "Territory enclosed within another one" , "Minority culture living within larger group" , "Group differing in ethnicity from surrounding people" .)
