Park in Arizona? (7)
I believe the answer is:
phoenix
This clue might be a double definition.
'park' is the first definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'in arizona?' is the second definition.
(Phoenix is the capital of Arizona)
Can you help me to learn more?
(Other definitions for phoenix that I've seen before include "Legendary bird said to emerge from the ashes of itself" , "One able to rise from the ashes" , "25 28 [MARS LANDER]" , "part of Arizona" , "Arizona city (that rose from the ashes?)" .)
