Fictional owner of a magic lamp (7)
I believe the answer is:
aladdin
'fictional owner of a magic lamp' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for aladdin that I've seen before include "Pantomime boy with wonderful lamp" , "12" , "Pantomime boy with magic lamp" , "Dial Dan for pantomime character with magic lamp" , "Magical lamp rubber" .)
