<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">crow's call</span>' is the definition.<br/ ><span class="explanation-format__explanation">(sound made by a crow)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for caw that I've seen before include "Rook's cry" , "Harsh cry of a crow" , "Crow's call" , "Cry of a rook" , "Crow utterance" .)
