Woman repeated phrase for lawman (7)
I believe the answer is:
sheriff
'for lawman' is the definition.
(sheriff is a kind of lawman)
'woman repeated phrase' is the wordplay.
'woman' becomes 'she'.
'repeated phrase' becomes 'riff' (I've seen this in another clue).
'she'+'riff'='SHERIFF'
(Other definitions for sheriff that I've seen before include "Scottish judge" , "Lawman of the wild west" , "American lawman" , "Crown's chief executive in a county" , "Chief officer of the Crown in a county" .)
