State intervening in Egyptian aid, Nile rising (7)
I believe the answer is:
indiana
'state' is the definition.
(US state)
'intervening in egyptian aid nile rising' is the wordplay.
'intervening in' indicates a hidden word (the answer appears or intervenes in the clue).
'rising' shows that the letters should be reversed in order (going up in a down clue).
'anaidni' is hidden within 'egyptian aid nile'.
'anaidni' in reverse letter order is 'INDIANA'.
(Other definitions for indiana that I've seen before include "Part of US" , "--- Jones, Harrison Ford film character" , "state of America" , "Character associated with the Temple of Doom" , "American state" .)
