Wonderland girl (5)
I believe the answer is:
alice
'wonderland girl' is the definition.
(I've seen this in another clue)
'girl' is the wordplay.
I cannot really see how this works, but
'girl' could be 'ali' (girl's name) and 'ali' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for alice that I've seen before include "Girl famed for Wonderland adventures" , "Wonderland girl; --- B. Toklas" , "Girl in literary Wonderland" , "Lewis Carroll's heroine" , "band" .)
