Complete or whole (8)
I believe the answer is:
unbroken
I believe this clue is a double definition.
'complete' is the first definition.
(similar in meaning)
'whole' is the second definition.
(I've seen this in another clue)
(Other definitions for unbroken that I've seen before include "Not surpassed" , "Intact" , "not trained for riding" , "One-piece" , "Complete" .)
