Wildlife region requiring a warm coat (5)
I believe the answer is:
parka
'warm coat' is the definition.
(I've seen this before)
'wildlife region requiring a' is the wordplay.
I cannot quite understand how this works, but
'region' could be 'park' (park is a kind of region) and 'park' is found in the answer.
'a' is within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for parka that I've seen before include "Short, hooded coat" , "Anorak" , "Kind of heavy jacket" , "warm gear" , "hoodie" .)
