Carried round Pacific island (6)
I believe the answer is:
borneo
'pacific island' is the definition.
(I've seen this before)
'carried round' is the wordplay.
'carried' becomes 'borne' (I've seen this before).
'round' becomes 'o' (round can mean a round object).
'borne'+'o'='BORNEO'
(Other definitions for borneo that I've seen before include "Largest island of Asia" , "Island, part of the Malay archipelago" , "Island shared by Malaysia and Indonesia" , "Largest Asian island" , "Large Pacific island" .)
