Mixture I smoke is one from the far North (6)
I believe the answer is:
eskimo
'one from the far north' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'mixture i smoke' is the wordplay.
'mixture' indicates an anagram.
'i'+'smoke'='ismoke'
'ismoke' anagrammed gives 'ESKIMO'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for eskimo that I've seen before include "Owner of kayak" , "Less-preferred name for Inuit" , "Language" , "Former term for Inuit" , "arctic person" .)
