Archipelago's name appearing in old clothing (5)
I believe the answer is:
tonga
'archipelago's' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'name appearing in old clothing' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'appearing in' indicates putting letters inside.
'old clothing' becomes 'toga' (I've seen this before).
'n' inserted into 'toga' is 'TONGA'.
Can you help me to learn more?
(Other definitions for tonga that I've seen before include "Pacific Ocean kingdom" , "Pacific island state" , "S.W Pacific Kingdom" , "Islands once ruled by Queen Salote" , "SW Pacific monarchy" .)
