"Five gold rings!" garbled aunt in country (7)
I believe the answer is:
vanuatu
'country' is the definition.
(I know that Vanuatu is a country)
'five gold rings garbled aunt' is the wordplay.
'five' becomes 'V' (Roman numeral).
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'rings' means one lot of letters goes inside another (some letters are ringed or contained by others).
'garbled' is an anagram indicator.
'aunt' is an anagram of 'nuat'.
'au' enclosing 'nuat' is 'anuatu'.
'v'+'anuatu'='VANUATU'
'in' is the link.
(Other definitions for vanuatu that I've seen before include "South Pacific Ocean nation of 80 islands" , "Pacific island country, formerly New Hebrides" , "Country of the south-west Pacific" , "Archipelago, formerly known as New Hebrides" , "Southwest Pacific island hit by Cyclone Pam in March" .)
