Early enough to make it mine (2,4)
I believe the answer is:
in time
'early enough' is the definition.
(thesaurus)
'make it mine' is the wordplay.
'make' indicates anagramming the letters.
'it'+'mine'='itmine'
'itmine' with letters rearranged gives 'IN TIME'.
'to' acts as a link.
(Other definitions for in time that I've seen before include "not too late" , "Early enough" , "What musicians aim to be" , "Later perhaps" , "What an orchestra should be" .)
