City in Egypt or Illinois (5)
I believe the answer is:
cairo
'city in egypt or illinois' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cairo that I've seen before include "African city" , "Al Qahira" , "City near the Nile delta" , "Capital city on the Nile" , "Egypt's capital" .)
