Gold inside damaged urn on Pacific island (5)
I believe the answer is:
nauru
'pacific island' is the definition.
(I've seen this before)
'gold inside damaged urn' is the wordplay.
'gold' becomes 'au' (Au is the chemical symbol for gold).
'inside' means one lot of letters goes inside another.
'damaged' indicates anagramming the letters.
'urn' with letters rearranged gives 'nru'.
'au' going into 'nru' is 'NAURU'.
'on' is the link.
(Other definitions for nauru that I've seen before include "Fairground carousel" , "Pacific island country" , "Smallest Pacific state" , "Island country in Micronesia" , "Pacific republic, formerly Pleasant Island" .)
