Wounds with a wild thrust, almost (5)
I believe the answer is:
hurts
'wounds' is the definition.
(I know this)
'wild thrust almost' is the wordplay.
'wild' is an anagram indicator.
'almost' means to remove the last letter (most of the word but not all of it).
'thrust' with its final letter taken off is 'thrus'.
'thrus' is an anagram of 'HURTS'.
'with a' acts as a link.
(Other definitions for hurts that I've seen before include "causes damage" , "pain" , "Damages" .)
