Sexually precocious young girl (6)

I believe the answer is:

lolita

(Other definitions for lolita that I've seen before include "Nabokov female" , "Eponymous nymphette created in novel by Nabokov" , "Literary nymphet" , "Nabokov's girl" , "Precocious Nabokov heroine" .)

I've seen this clue in The Guardian.
