<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">violin part</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 neck that I've seen before include "Isthmus; impudence (sl.)" , "Canoodle; isthmus" , "Adam's apple location" , "Body part and the nerve to do something" , "Kiss amorously" .)
