Wherein, shopping, one can get scared (but not wet) (7)
I believe the answer is:
arcades
'wherein shopping' is the definition.
I can't judge whether this defines the answer.
'one can get scared but not wet' is the wordplay.
I cannot really understand how this works, but
'one' could be 'a' (a thing is one thing) and 'a' is present in the answer.
an anagram of 'scared' is 'rcades' which is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for arcades that I've seen before include "Arched walks" , "Covered passageway with shops and stalls" , "Covered walkways" , "Covered areas with shops" , "More than one mall" .)
