Where it's cold, the police get rid of ice (having a right) (5)
I believe the answer is:
polar
'where it's cold' is the definition.
The definition suggests a singular noun but the answer is not.
'police get rid of ice having a right' is the wordplay.
'get rid of' is a deletion indicator.
'having' is a charade indicator (letters next to each other).
'a right' becomes 'ar' (I've seen this in other clues).
'police' with 'ice' removed is 'pol'.
'pol'+'ar'='POLAR'
'the' is the link.
Can you help me to learn more?
(Other definitions for polar that I've seen before include "Relating to the ends of the Earth" , "Kind of bear or opposite" , "From one end of the Earth or the other" , "extremes of 3 or 26 [NORTH OR SOUTH]" , "Of the frozen regions" .)
