Lets her off in refuge (7)
I believe the answer is:
shelter
'refuge' is the definition.
(thesaurus)
'lets her off' is the wordplay.
'off' is an anagram indicator.
'lets'+'her'='letsher'
'letsher' with letters rearranged gives 'SHELTER'.
'in' acts as a link.
(Other definitions for shelter that I've seen before include "Place of refuge" , "Sanctuary, protection" , "'Refuge, cover (7)'" , "Find refuge" , "Let hers go into shielded place" .)
