Plain city where tailless school cat raised (8)
I believe the answer is:
gomorrah
This clue could be a double definition.
'plain city' is the first definition.
(cities of the plain from Genesis)
'where tailless school cat raised' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for gomorrah that I've seen before include "Biblical town twinned with Sodom" , "With Sodom, a depraved town of ancient Palestine" , "doomed city" , "wicked city" , "Sodom and ........ were notorious Biblical cities" .)
