Light weight raised in an air-conditioned state (7)
I believe the answer is:
arizona
'light' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'weight raised in an air-conditioned state' is the wordplay.
'weight' becomes 'oz'.
'raised' says the letters should be written backwards (going up in a down clue).
'in' indicates putting letters inside.
'an' becomes 'a'.
'air conditioned state' becomes 'rina' (I am not sure about this - if you are sure you should believe this answer much more).
'oz' in reverse letter order is 'zo'.
'a'+'rina'='arina'
'zo' put within 'arina' is 'ARIZONA'.
Can you help me to learn more?
(Other definitions for arizona that I've seen before include "American state, capital Phoenix" , "State of SW USA" , "State of southern US" , "Site of Grand Canyon" , "State of southwest USA" .)
