States things are breaking in camera shot (9)
I believe the answer is:
americana
'states things' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'are breaking in camera shot' is the wordplay.
'are' becomes 'a' (the 'are' is a metric unit of area).
'breaking' is an insertion indicator.
'shot' indicates an anagram.
'in'+'camera'='incamera'
'incamera' is an anagram of 'americna'.
'a' put into 'americna' is 'AMERICANA'.
Can you help me to learn more?
(Other definitions for americana that I've seen before include "Uncle Sam's things" , "Traditional music" , "Things linked to the US" , "Things associated with the US" , "Wild West material?" .)
