<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">indentations</span>' is the definition.<br/ ><span class="explanation-format__explanation">(notch is a kind of indentation)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for notches that I've seen before include "Nicks" , "Makes small indentation in" , "Small v-shaped cuts" , "V-Shaped cuts or indentations" , "Small indentations found on chest" .)
