Island capital as a sun resort (6)
I believe the answer is:
nassau
'island capital' is the definition.
'Nassau' can be an answer for 'capital' (capital of the Bahamas). I'm not sure about the 'island' bit.
'as a sun resort' is the wordplay.
'resort' indicates anagramming the letters (re-sort the letters).
'as'+'a'+'sun'='asasun'
'asasun' with letters rearranged gives 'NASSAU'.
Can you help me to learn more?
(Other definitions for nassau that I've seen before include "Saunas (anag)" , "city" , "Dublin street in the Bahamas?" , "Caribbean resort" , "Capital of the Bahamas" .)
