She has her own house (5)
I believe the answer is:
wendy
'she' is the definition.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for wendy that I've seen before include "31's friend" , "Girl associated with 13" , "Peter Pan heroine" , "Art-loving Sister (TV)" , "Peter Pan's friend" .)
