Cad some outsiders condemn (5)
I believe the answer is:
curse
'condemn' is the definition.
(thesaurus)
'cad some outsiders' is the wordplay.
'cad' becomes 'cur' (I've seen this in another clue).
'outsiders' means to remove the middle letters (only the letters on the outside of the word remain).
'some' with its middle removed is 'se'.
'cur'+'se'='CURSE'
(Other definitions for curse that I've seen before include "Cause of harm or misery" , "Invoke evil upon" , "Anathema" , "Evil spell - oath" , "Excommunication" .)
