Ungovernable (7)

I believe the answer is:

wayward

(Other definitions for wayward that I've seen before include "Stubborn" , "Childishly self-willed, unruly" , "Capricious and undisciplined" , "Resistant to discipline" , "Undisciplined, headstrong" .)

I've seen this clue in The Sun and the King Feature Syndicate.
