Confused by many an editor (5)
I believe the answer is:
mixed
'confused' is the definition.
(thesaurus)
'many an editor' is the wordplay.
'many an' becomes 'mix' (I can't justify this - if you can you should give a lot more credence to this answer).
'editor' becomes 'ed'.
'mix'+'ed'='MIXED'
'by' is the link.
Can you help me to learn more?
(Other definitions for mixed that I've seen before include "Varied" , "Mingled" , "Miscellaneous" , "Assorted" , "Blended" .)
