Girl in good novel by Jane Austen (5)
I believe the answer is:
gemma
'girl' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'good novel by jane austen' is the wordplay.
'good' becomes 'g' (abbreviation).
'novel by jane austen' becomes 'emma' (I've seen this in another clue).
'g'+'emma'='GEMMA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for gemma that I've seen before include "girl" , "Bud" , "Girl's name" .)
