I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">preside over a meeting</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for chair that I've seen before include "Prof's post; meeting leader" , "Seat for one person" , "Top seat of committee" , "Presiding officer" , "Get seat" .)
