Igloo man built in sparsely populated country (8)
I believe the answer is:
mongolia
'sparsely populated country' is the definition.
'Mongolia' can be an answer for 'country' (Mongolia is an example). I am not certain of the 'sparsely populated' bit.
'igloo man built' is the wordplay.
'built' is an anagram indicator.
'igloo'+'man'='iglooman'
'iglooman' with letters rearranged gives 'MONGOLIA'.
'in' is the link.
Can you help me to learn more?
(Other definitions for mongolia that I've seen before include "Republic of east central Asia" , "Log Naomi into the vast region in Asia" , "Log Naomi into the vast Asian region" , "Country between China/Russia" , "Eastern state" .)
