Pragmatic attitude is found in kingdom (7)
I believe the answer is:
realism
'pragmatic attitude' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe there's an association between them I don't understand?
'is found in kingdom' is the wordplay.
'found in' means one lot of letters goes inside another.
'kingdom' becomes 'realm' (kingdom is a type of country or realm).
'is' put within 'realm' is 'REALISM'.
Can you help me to learn more?
(Other definitions for realism that I've seen before include "True-to-life quality" , "Pragmatism" , "Practical approach" , "Art genre that is true to life" , "Unromantic view of the world" .)
