Wild desire of a fellow to get a first-class return (5)
I believe the answer is:
mania
'wild desire' is the definition.
'mania' can be an answer for 'desire' (thesaurus). I'm not sure about the 'wild' bit.
'a fellow to get a first-class return' is the wordplay.
'a fellow' becomes 'man' (fellow can mean a man).
'to get' says to put letters next to each other.
'a first class' becomes 'ai' (Am - top quality).
'return' says the letters should be written backwards.
'ai' in reverse letter order is 'ia'.
'man'+'ia'='MANIA'
'of' is the link.
Can you help me to learn more?
(Other definitions for mania that I've seen before include "Madness - craze" , "Obsessive enthusiasm" , "Passion -- mood disorder" , "Craze; overexcitement" , "A (violent) mood disorder" .)
