Error in casting Cinderela? (8,7)
I believe the answer is:
spelling mistake
'error' is the definition.
(I've seen this before)
'in casting cinderela?' is the wordplay.
I cannot quite see how this works, but
'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spelling mistake that I've seen before include "Error" , "Harry Potter might make?" .)
