I believe the answer is:
logo
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">company symbol</span>' is the definition.<br/ ><span class="explanation-format__explanation">(a corporate symbol)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for logo that I've seen before include "Vigour; relish" , "Printed symbol as organisation's emblem" , "(Company) symbol" , "Emblematic design" , "A firm's sign or symbol" .)
