Pick out record by Queen -- Queen's last (7)
I believe the answer is:
discern
'pick out' is the definition.
('discern' can be a synonym of 'pick out')
'record by queen queen's last' is the wordplay.
'record' becomes 'disc' ('disc' can be a synonym of 'record'**).
'by' is a charade indicator (letters next to each other).
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'last' indicates one should take the final letters.
The last letter of 'queen' is 'n'.
'disc'+'er'+'n'='DISCERN'
(Other definitions for discern that I've seen before include "Espy" , "Detect" , "Make out, distinguish by eye" , "Perceive - distinguish" , "Cinders (anag)" .)
