No current story brought about much joy (7)
I believe the answer is:
elation
'much joy' is the definition.
'elation' can be an answer for 'joy' (I've seen this before). I am not sure about the 'much' bit.
'no current story brought about' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'story' becomes 'tale' (synonyms).
'brought about' is a reversal indicator.
'no'+'i'+'tale'='noitale'
'noitale' back-to-front is 'ELATION'.
Can you help me to learn more?
(Other definitions for elation that I've seen before include "Feeling of joy and pride" , "High feeling?" , "Transport" , "It's a great feeling!" , "Euphoria of toenail" .)
