Very hungry creature flying round us (8)
I believe the answer is:
ravenous
'very hungry' is the definition.
(I've seen this before)
'creature flying round us' is the wordplay.
'creature flying' becomes 'raven' (I can't justify this - if you can you should believe this answer much more).
'round' becomes 'o' (round can mean a round object).
'raven'+'o'+'us'='RAVENOUS'
Can you help me to learn more?
(Other definitions for ravenous that I've seen before include "Intensely hungry" , "Famished" , "A nervous way to be very hungry" , "starved?" , "Extremely hungry" .)
