Colder than Coventry for those sent into isolation? (7)
I believe the answer is:
siberia
'isolation?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for siberia that I've seen before include "Cold spot" , "Arctic region" , "chosen by Putin for no-frills travel?" , "a place often very cold" , "Area of eastern Russia" .)
