Bad cut with end of knife (6)
I believe the answer is:
severe
'bad' is the definition.
(similar in meaning)
'cut with end of knife' is the wordplay.
'cut' becomes 'sever' (to sever is to cut or split).
'with end of knife' becomes 'e' (I can't explain this - if you can you should believe this answer much more).
'sever'+'e'='SEVERE'
Can you help me to learn more?
(Other definitions for severe that I've seen before include "Harsh, rigorous" , "Plain, hard" , "Intense; harsh" , "Austere, harsh (6)" , "'Strict, harsh (6)'" .)
