Invest one shilling in India and get a country of islands (9)
I believe the answer is:
indonesia
'get a country of islands' is the definition.
I can't judge whether this definition defines the answer.
'invest one shilling in india' is the wordplay.
'invest' becomes 'one' (I am not sure about this - if you are sure you should believe this answer much more).
'one shilling' becomes 's'.
'in' means one lot of letters goes inside another.
'one'+'s'='ones'
'ones' inserted within 'india' is 'INDONESIA'.
'and' is the link.
Can you help me to learn more?
(Other definitions for indonesia that I've seen before include "Asian country, capital Jakarta" , "part of Asia" , "Muslim republic" , "somewhere in Asia" , "SE Asian country" .)
