H, in Greece (3)
I believe the answer is:
eta
'h in greece' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eta that I've seen before include "Something like 10 [RHO]" , "Arrival roughly indicated" , "Letter of Greek alphabet" , "indicating when flight is due" , "when you can hope to receive it" .)
