Clumsy samurai with the wound (10)
I believe the answer is:
amateurish
'clumsy' is the definition.
(thesaurus)
'samurai with the wound' is the wordplay.
'with' says to put letters next to each other.
'wound' indicates an anagram (wound can mean twisted or turned around).
'samurai' after 'the' is 'thesamurai'.
'thesamurai' anagrammed gives 'AMATEURISH'.
(Other definitions for amateurish that I've seen before include "done imperfectly" , "Unprofessional" , "rather inept" , "Not very professional" , "using little craft, perhaps" .)
