New desire to live (6)
I believe the answer is:
reside
'live' is the definition.
(I know that reside is a more specific form of the action live)
'new desire' is the wordplay.
'new' indicates an anagram.
'desire' with letters rearranged gives 'RESIDE'.
'to' acts as a link.
(Other definitions for reside that I've seen before include "Make one's home permanently" , "Dwell in desire" , "'Live, dwell (6)'" , "Live (at an address)" , "Live in permanently" .)
