Talk incoherently with us in French, being very, very hungry (8)
I believe the answer is:
ravenous
'very very hungry' is the definition.
'ravenous' can be an answer for 'hungry' (similar in meaning). I'm not certain of the 'very very' bit.
'talk incoherently with us in french' is the wordplay.
'talk incoherently' becomes 'rave' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'us in french' becomes 'nous' (I can't justify this - if you can you should give a lot more credence to this answer).
'rave'+'nous'='RAVENOUS'
'being' is the link.
Can you help me to learn more?
(Other definitions for ravenous that I've seen before include "needing to be fed" , "Extremely hungry" , "Voracious" , "Voraciously hungry" , "Really hungry, could eat a horse" .)
