Much talk of seeking asylum (3)
I believe the answer is:
gas
'much talk' is the definition.
'gas' can be an answer for 'talk' (gas can mean to chat). I'm not sure about the 'much' bit.
'of seeking asylum' is the wordplay.
'of' says the answer is hidden in the clue.
'GAS' can be found hidden inside 'seeking asylum'.
Can you help me to learn more?
(Other definitions for gas that I've seen before include "person who's amusing ..." , "Talk idly; fuel" , "In brief, American petrol" , "Eg, oxygen" , "Oxygen is one" .)
