Jump over net (5)
I believe the answer is:
clear
This clue is a double definition.
'jump over' is the first definition.
(I've seen this before)
'net' is the second definition.
('clear' can be similar in meaning to 'net')
(Other definitions for clear that I've seen before include "Empty - vault" , "Free from blame" , "bound over" , "Easily understood" , "beyond doubt" .)
