Pacific islands import south Indian food (6)
I believe the answer is:
samosa
'indian food' is the definition.
'pacific islands import south' is the wordplay.
'pacific islands' becomes 'samoa' (I've seen this before. I am not sure about the 'pacific' bit.).
'import' means one lot of letters goes inside another.
'south' becomes 's' (synonyms).
'samoa' enclosing 's' is 'SAMOSA'.
Can you help me to learn more?
(Other definitions for samosa that I've seen before include "Stuffed Indian pastry" , "Savoury Indian snack" , "Small Indian cake of meat or vegetables" , "tasty snack" , "Small Indian pastry of meat or vegetables" .)
