Word-of-mouth (4)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">word-of-mouth</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 oral that I've seen before include "from the trap" , "Ant; tourist (dial.)" , "Kind of examination" , "Of the voice" , "Kind of exam" .)
