I believe the answer is:
trespass
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">encroach</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that encroach is a more specific form of the action trespass)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for trespass that I've seen before include "Sin (archaic)" , "Go out of bounds" , "Enter someone else's property illegally" , "Enter land without permission" , "sin in the eyes of the church" .)
