Country you can possibly sail round at last (6)
I believe the answer is:
island
'country you can' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'sail round at last' is the wordplay.
'round' indicates anagramming the letters.
'at last' becomes 'nd' (I can't justify this - if you can you should give a lot more credence to this answer).
'sail' anagrammed gives 'isla'.
'isla'+'nd'='ISLAND'
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for island that I've seen before include "See 1" , "Malta, say" , "Ground surrounded by water" , "Pedestrian area in middle of road crossing" , "Eg, Sardinia or Java" .)
