Cold area in a southerly peninsula (7)
I believe the answer is:
siberia
'cold area' is the definition.
(I've seen this before)
'a southerly peninsula' is the wordplay.
'a southerly' becomes 's' (this could be a standard abbreviation which I don't know about).
'peninsula' becomes 'Iberia' (peninsula including Spain and Portugal).
's'+'iberia'='SIBERIA'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for siberia that I've seen before include "Russian far-east" , "Cold spot" , "Large E. Russian region" , "Region to which Russian and then Soviet governments sent those considered disloyal" , "Arctic region" .)
