State said Nile keeps rising (5)
I believe the answer is:
india
'state' is the definition.
(India is an example)
'said nile keeps rising' is the wordplay.
'keeps' indicates the answer is hidden within the clue.
'rising' says the letters should be written in reverse (going up in a down clue).
'aidni' can be found hidden inside 'said nile'.
'aidni' backwards is 'INDIA'.
(Other definitions for india that I've seen before include "A Passage to - (E.M. Forster)" , "vast country" , "IDA in the country?" , ""Bharat", locally" , "Part of Asia" .)
