Stand before entrance doing twirl (7)
I believe the answer is:
etagere
'stand' is the definition.
(stand for displaying objects)
'before entrance doing twirl' is the wordplay.
'before' becomes 'ere' (poetic term for 'before').
'entrance doing' becomes 'gate' (I can't explain this - if you can you should give a lot more credence to this answer).
'twirl' shows that the letters should be reversed in order (I've seen 'twirling' mean this).
'ere'+'gate'='eregate'
'eregate' reversed gives 'ETAGERE'.
Can you help me to learn more?
(Other definitions for etagere that I've seen before include "Stand of shelves" , "Piece of furniture for displaying small ornaments" , "Shelved display stand" , "Furniture item with shelves" , "Shelved furniture item" .)
