Dotty, Brody and Nye discovered going after Eve, Tom, Dick and Harry (9)
I believe the answer is:
everybody
'tom dick and harry' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'dotty brody and nye discovered going after eve' is the wordplay.
'dotty' is an anagram indicator (dotty can mean mad).
'and' is a charade indicator (letters next to each other).
'discovered' indicates the central letters (dis-covered - outer letters removed).
'going after' says to put letters next to each other.
The middle of 'nye' is 'y'.
'brody' put after 'y' is 'ybrody'.
'ybrody' anagrammed gives 'rybody'.
'rybody' put after 'eve' is 'EVERYBODY'.
Can you help me to learn more?
(Other definitions for everybody that I've seen before include "One and all" , "All persons" , "All and sundry" , "people generally?" .)
