Persistently nag (7)
I believe the answer is:
henpeck
'persistently nag' is the definition.
This is all the clue.
(Other definitions for henpeck that I've seen before include "Browbeat" , "(Of a woman) continually criticise (a husband)" , "Nag as domestic fowl might" , "Nag a husband" , "Harass (husband)" .)
