Tale of ultimate passion and wild love (5)
I believe the answer is:
novel
'tale' is the definition.
(thesaurus)
'ultimate passion and wild love' is the wordplay.
'ultimate' indicates one should take the final letters.
'and' is a charade indicator (letters next to each other).
'wild' indicates anagramming the letters.
The final letter of 'passion' is 'n'.
'love' anagrammed gives 'ovel'.
'n'+'ovel'='NOVEL'
'of' is the link.
(Other definitions for novel that I've seen before include "Fictitious prose work" , "New and strange" , "Innovative" , "Of a kind not seen before" , "Fictional work" .)
