Girl allowed by her aunt in Paris to be a dabbler (10)
I believe the answer is:
dilettante
'a dabbler' is the definition.
('dilettante' can be a synonym of 'dabbler')
'girl allowed by her' is the wordplay.
'girl' becomes 'di'.
'allowed' becomes 'let' (I've seen this before).
'by' is a charade indicator (letters next to each other).
'her' becomes 'tante' (I can't justify this - if you can you should give a lot more credence to this answer).
'di'+'let'+'tante'='DILETTANTE'
'aunt in paris to be' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
(Other definitions for dilettante that I've seen before include "Superficial dabbler in the arts - title at end (anag)" , "Amateur art lover" , "Superficial art lover" , "whose study is superficial?" , "Aesthete" .)
