Return of Queen meaning Queen record (8)
I believe the answer is:
register
'record' is the definition.
(I know that record can be written as register)
'return of queen meaning queen' is the wordplay.
'return of' says the letters should be written in reverse.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'meaning' becomes 'gist' (gist is a kind of meaning).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'er' in reverse letter order is 're'.
're'+'gist'+'er'='REGISTER'
(Other definitions for register that I've seen before include "(Put one's name down on) list" , "part of our paper" , "Greet sir (anag.)" , "Official list or record" , "Log" .)
