Being confused, I'm wrong to get cross with the editor (5)
I believe the answer is:
mixed
'being confused' is the definition.
(thesaurus)
'i'm wrong to get cross with the editor' is the wordplay.
'wrong' is an anagram indicator.
'to get' is a charade indicator (letters next to each other).
'cross' becomes 'x' (an X is a cross).
'with' is a charade indicator (letters next to each other).
'the editor' becomes 'ed' (abbreviation).
'im' is an anagram of 'mi'.
'mi'+'x'+'ed'='MIXED'
(Other definitions for mixed that I've seen before include "Blended" , "Mingled" , "Miscellaneous" , "For both sexes" , "Varied" .)
