Spinning round bar (3)
I believe the answer is:
inn
'spinning round bar' is the definition.
'inn' can be an answer for 'bar' (both can mean a drinking establishment). I am unsure of the 'spinning round' bit.
'spinning round bar' is the wordplay.
'bar' indicates a hidden word (I've seen 'bars' mean this (the answer is imprisoned or barred in the clue)).
'round' says the letters should be written in reverse.
'nni' is hidden within 'spinning'.
'nni' written backwards gives 'INN'.
Can you help me to learn more?
(Other definitions for inn that I've seen before include "watering hole" , "One of Lincoln's" , "Hotel or public house" , "Small hotel or country pub" , "Hostel" .)
