Mobile's location in diorama balanced in retrospect (7)
I believe the answer is:
alabama
'mobile's location' is the definition.
'Alabama' can be an answer for 'location' (Alabama is an example). I am not certain of the 'mobile's' bit.
'in diorama balanced in retrospect' is the wordplay.
'in' indicates the answer is hidden within the clue.
'in retrospect' says the letters should be written backwards.
'amabala' is hidden in the letters of 'diorama balanced'.
'amabala' in reverse letter order is 'ALABAMA'.
Can you help me to learn more?
(Other definitions for alabama that I've seen before include "Southern US state" , "Confederate state during the American Civil War" , "US state on the Gulf of Mexico" , "Source of cotton" , "Somewhere in US" .)
