Parson crazed with love for a trebly gifted female (7)
I believe the answer is:
soprano
'a trebly gifted female' is the definition.
I can't tell whether this defines the answer.
'parson crazed with love' is the wordplay.
'crazed with' is an anagram indicator (a crazy order of the letters).
'love' becomes 'o' (love means zero in tennis).
'parson' with its letters mixed up with 'o' gives 'SOPRANO'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for soprano that I've seen before include "(Singer of) the highest vocal range" , "Producer of high-pitched sounds" , "Norman, perhaps" , "Sutherland?" , "Highest adult female voice" .)
