That he's new to here is more surprising (8)
I believe the answer is:
stranger
'that he's new to here is more surprising' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'that he's' is the wordplay.
I cannot quite see how this works, but
'he' could be 'ange' and 'ange' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stranger that I've seen before include "Person in place or company to which he does not belong" , "unfamiliar figure" , "One who is little known" , "Unfamiliar person" , "More odd or wierd" .)
