<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">small wave</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for ripple that I've seen before include "A small wave, or a gentle sound as of laughter" , "Slight surface wave" , "Slight disturbance on water's surface" , "Type of ice cream with coloured syrup" , "Small wave or surface disturbance" .)
