She made a new start after breaking a heel (5)
I believe the answer is:
helen
'she' is the definition.
'a new start after breaking a heel' is the wordplay.
'start' says to take the initial letters.
'after' means one lot of letters go next to another.
'breaking' indicates anagramming the letters.
The initial letter of 'new' is 'n'.
'heel' with letters rearranged gives 'hele'.
'n' after 'hele' is 'HELEN'.
'made' is the link.
(Other definitions for helen that I've seen before include "femme fatale" , "beautiful woman" , "She started Trojan War" , "Famous classical beauty" , "Was this the face that launch'd a thousand ships?" .)
