Did (8)
I believe the answer is:
executed
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">did</span>' is the definition.<br/ ><span class="explanation-format__explanation">(executing is a kind of doing)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for executed that I've seen before include "Produced" , "Done (to death?)" , "Performed" , "Carried out the task or put to death" , "Put a plan into effect" .)
