queen

I'm a little stuck... Click here to teach me more about this clue!

'name' is the definition.
(I know that queen is a noble title)

I can't explain the rest of the clue.

(Other definitions for queen that I've seen before include "Tom's partner" , "who collaborated musically with 14 [BOWIE]" , "Rock group; royal personage" , "Empress" , "Ruling lady" .)

I've seen this clue in The Independent.
