Try again to wound (4)
I believe the answer is:
gore
'wound' is the definition.
(I've seen this before)
'try again' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'again' becomes 're'.
'go'+'re'='GORE'
'to' is the link.
(Other definitions for gore that I've seen before include "Make a hole in" , "stuff from part of Kensington" , "Blood; stab with tusk" , "Clotted blood" , "Blood that's been shed" .)
