It's partly glacial -- ask any native (7)
I believe the answer is:
alaskan
'native' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'it's partly glacial ask any' is the wordplay.
'it's partly' indicates a hidden word (part of the clue is used).
'ALASKAN' can be found hidden inside 'glacial ask any'.
Can you help me to learn more?
(Other definitions for alaskan that I've seen before include "Of a northern US state" , "native of Juneau?" , "Citizen of the 49th state of the USA" , "One from Juneau, say" , "one used to harsh conditions" .)
