Deliberate damage making a beast go, possibly (8)
I believe the answer is:
sabotage
'deliberate damage' is the definition.
(I've seen this before)
'a beast go possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'a'+'beast'+'go'='abeastgo'
'abeastgo' is an anagram of 'SABOTAGE'.
'making' acts as a link.
(Other definitions for sabotage that I've seen before include "Deliberate damage (eg, in wartime)" , "Got a base (anag.)" , "Subvert" , "Wreck" , "Deliberate act of destruction or disruption" .)
