Where, abroad, rabies is regulated (6)
I believe the answer is:
serbia
'where abroad' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'rabies is regulated' is the wordplay.
'is regulated' indicates an anagram.
'rabies' anagrammed gives 'SERBIA'.
Can you help me to learn more?
(Other definitions for serbia that I've seen before include "Rabies in former Yugoslavia" , "Belgrade's country" , "part of Europe" , "European country (bordering on 1 across)" , "South-east European country" .)
