I believe the answer is:
oppress
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">persecute</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that persecute can be written as oppress)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for oppress that I've seen before include "Keep in subjection and hardship" , "'Persecute, come down heavy on (7)'" , "Govern harshly, weigh down with care" , "Govern cruelly" , "Treat harshly" .)
