City near Phoenix (4)
I believe the answer is:
mesa
'city near phoenix' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mesa that I've seen before include "Flat-topped mountain" , "In the US south-west, a steep-sided flat-topped hill" , "Flat-topped tableland" , "High land" , "Flat hill" .)
