No hints in Christian name from us? (8)
I believe the answer is:
american
'us?' is the definition.
(I've seen this before)
'no hints in christian name' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'n' (common abbreviation) and 'n' is found in the answer.
'name' could be 'erica' and 'erica' is found in the answer.
The remaining letters 'am' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'from' acts as a link.
Can you help me to learn more?
(Other definitions for american that I've seen before include "The nationality is in camera, oddly" , "Inhabitant of the States" , "Main race (anag.)" , "Person from the US" , "Citizen seen in Cinerama" .)
