Reason UV makes you hungry? (8)
I believe the answer is:
ravenous
'hungry?' is the definition.
(similar in meaning)
'reason uv makes' is the wordplay.
'makes' indicates anagramming the letters.
'reason'+'uv'='reasonuv'
'reasonuv' with letters rearranged gives 'RAVENOUS'.
'you' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ravenous that I've seen before include "Voraciously hungry" , "Really hungry, ready to devour" , "Wolfish" , "Famished" , "needing to be fed" .)
