Empty talk out of the ring? (3)
I believe the answer is:
gas
'empty talk' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gas that I've seen before include "Oxygen maybe" , "eg Helium" , "Fumes, vapour" , "idle chit-chat" , "Talk profusely" .)
