Lovely, talented, enthralling girl (8)
I believe the answer is:
adorable
'lovely' is the definition.
('adorable' can be a synonym of 'lovely')
'talented enthralling girl' is the wordplay.
'talented' becomes 'able' (I've seen this before).
'enthralling' means one lot of letters goes inside another.
'girl' becomes 'dora'.
'able' enclosing 'dora' is 'ADORABLE'.
(Other definitions for adorable that I've seen before include "Lovely and attractive" , "Winsome" , "Quite delightful, fit to be worshipped" , "Inspiring love" , "Worthy of worship" .)
