Hard getting over boundary fence (5)
I believe the answer is:
hedge
'fence' is the definition.
(hedge is a kind of fence)
'hard getting over boundary' is the wordplay.
'hard' becomes 'h'.
'getting' is a charade indicator (letters next to each other).
'over boundary' becomes 'edge' ('edge' can be a synonym of 'boundary'. I am not sure about the 'over' bit.**).
'h'+'edge'='HEDGE'
Can you help me to learn more?
(Other definitions for hedge that I've seen before include "sort of fund" , "cover?" , "Boundary; equivocate" , "avoid making commitments" , "take evasive action" .)
