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