Unfriendly attitude in Arctic bear (4,8)
I believe the answer is:
cold shoulder
'unfriendly attitude' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'arctic bear' is the wordplay.
'arctic' becomes 'cold' (similar in meaning).
'bear' becomes 'shoulder' (both can mean to carry or take responsibility for).
'cold'+'shoulder'='COLD-SHOULDER'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cold shoulder that I've seen before include "Show indifference" , "Snub" , "Ought to put in cooler!" , "left-over joint?" , "Ignore" .)
