Happy man found after appeals (7)
I believe the answer is:
pleased
'happy' is the definition.
(synonyms)
'man found after appeals' is the wordplay.
'man' becomes 'ed' (short for Edward).
'found after' means one lot of letters go next to another.
'appeals' becomes 'pleas' (plea is a kind of appeal).
'ed' after 'pleas' is 'PLEASED'.
(Other definitions for pleased that I've seen before include "Glad" , "Happy, satisfied" , "Euphoric" , "Gratified" , "Content" .)
