Record about meaning by Queen (8)
I believe the answer is:
register
'record' is the definition.
(register is a kind of record)
'about meaning by queen' is the wordplay.
'about' becomes 're' (regarding**).
'meaning' becomes 'gist' (gist is a kind of meaning).
'by' says to put letters next to each other.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
're'+'gist'+'er'='REGISTER'
(Other definitions for register that I've seen before include "Official record of names etc." , "Enrol, to vote perhaps" , "New arrival at hotel will" , "(Enrol in) list" , "Obituary" .)
