<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">religion founder</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for buddha that I've seen before include "Siddhartha Gautama (c 563-483 BC)" , "Founder of an Indian religion and philosophy" , "statue in temple" , "Gautama; his statue" , "Founder of a world religion" .)
