Frothy talk from Gazza? (3)
I believe the answer is:
gas
'frothy talk' is the definition.
'gas' can be an answer for 'talk' (I've seen this before). I am unsure of the 'frothy' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for gas that I've seen before include "Talk idly; fuel" , "Eg, hydrogen" , "See 2" , "It's not liquid or solid, like American petrol" , "Something exciting" .)
