I believe the answer is:
impute
<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">ascribe</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that ascribe can be written as impute)</span><br/ ><br/ >'<span class="explanation-format__original">attribute</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that impute is a more specific form of the action attribute)</span><br/ ><br/ ></span>
(Other definitions for impute that I've seen before include "Attribute (something bad) to someone" , "Attribute to a source or cause" , "Ascribe (something unpleasant)" , "Ascribe (crime etc) to someone" , "Uptime (anag.)" .)
