Indicate if nervously accepting love can be an improvement (11)
I believe the answer is:
edification
'an improvement' is the definition.
(I have seen 'Moral improvement ' mean 'edification' so perhaps 'improvement' could also mean 'edification')
'indicate if nervously accepting love' is the wordplay.
'nervously' indicates an anagram.
'accepting' indicates putting letters inside (inserted letters are accepted).
'love' becomes 'o' (love means zero in tennis).
'indicate'+'if'='indicateif'
'indicateif' anagrammed gives 'edificatin'.
'edificatin' placed around 'o' is 'EDIFICATION'.
'can be' acts as a link.
(Other definitions for edification that I've seen before include "Process of moral improvement" , "What 2 [PHILOSOPHER]s seek" , "Moral instruction" , "Moral/intellectual improvement" , "enlightenment" .)
