Went over with a Yankee editor (7)
I believe the answer is:
perused
'went' is the definition.
The answer and definition can be both to do with perception as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?
'over with a yankee editor' is the wordplay.
'over' means one lot of letters go next to another.
'with' is a charade indicator (letters next to each other).
'a' becomes 'per' (eg 'one a day' means 'one per day').
'yankee' becomes 'us' (I can't explain this - if you can you should believe this answer much more).
'editor' becomes 'ed' (abbreviation).
'per' next to 'us' is 'perus'.
'perus' next to 'ed' is 'PERUSED'.
Can you help me to learn more?
(Other definitions for perused that I've seen before include "Browsed" , "Scanned" , "Studied" , "Read (something) very carefully" .)
