I believe the answer is:
gaffer
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">foreman</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that foreman can be written as gaffer)</span><br/ ><br/ >'<span class="explanation-format__original">boss</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(gaffer can informally mean a boss)</span><br/ ><br/ ></span>
(Other definitions for gaffer that I've seen before include "man in charge" , "Informal boss or foreman" , "Foreperson of a work squad" , "Chief electrician on a film set" , "one prone to blunder socially?" .)
