<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">make a speech</span>' is the definition.<br/ ><span class="explanation-format__explanation">(oratory is public speaking)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for orate that I've seen before include "Give a formal address" , "Pontificate" , "Speak pompously and at length" , "Make a flowery speech" , "Speak publicly" .)
