Charlie has utterly mad desire (7)
I believe the answer is:
craving
'desire' is the definition.
(I know that craving is a type of desire)
'charlie has utterly mad' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'has' is a charade indicator (letters next to each other).
'utterly mad' becomes 'raving' (raving can mean mad).
'c'+'raving'='CRAVING'
(Other definitions for craving that I've seen before include "Powerful desire" , "longing" , "Strongly desiring" , "Hunger" , "Intense feeling of desire" .)
