Get over fence, perhaps, without faults? (5)
I believe the answer is:
clear
I believe this clue is a double definition.
'get over fence perhaps' is the first definition.
(to clear a fence is to successfully jump over it)
'without faults?' is the second definition.
(eg clear skin is without faults)
(Other definitions for clear that I've seen before include "Plain; unblock" , "Easily understood" , "With no jams" , "Lucid; to empty" , "Easy to see or understand" .)
