Away from the borders, raid a hostile state (5)
I believe the answer is:
idaho
'state' is the definition.
(Idaho is an example)
'away from the borders raid a hostile' is the wordplay.
'away from the borders' indicates the answer is hidden within the clue (the letters that border the answer are removed).
'IDAHO' is hidden within 'raid a hostile'.
(Other definitions for idaho that I've seen before include "US state bordering Canada" , "State of NW US" , "American state, capital Boise (5)" , "The Gem State, known for its potatoes" , "US state, capital Boise" .)
