Perhaps Elizabeth’s band (5)
I believe the answer is:
queen
'band' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for queen that I've seen before include "Female cat" , "Tom's partner" , "One in a suit" , "Female monarch" , "Powerful woman" .)
