Authorise priest seizing house in this state (8)
I believe the answer is:
oklahoma
'this state' is the definition.
(Oklahoma is an example)
'authorise priest seizing house' is the wordplay.
'authorise' becomes 'ok' (oking is a kind of authorising).
'priest' becomes 'lama' (lama is a kind of priest).
'seizing' indicates putting letters inside.
'house' becomes 'ho' (abbreviation for house).
'lama' enclosing 'ho' is 'lahoma'.
'ok'+'lahoma'='OKLAHOMA'
'in' acts as a link.
(Other definitions for oklahoma that I've seen before include "American state and famous musical" , "Young woman" , "Look, a ham from the state" , "A holm oak for a musical" , "American state and great western musical" .)
