<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">comb and comb and comb</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 preen that I've seen before include "demonstrate pride" , "Vainly groom oneself" , "Groom with elaborate care" , "Dress with elaborate care" , "Groom (oneself) with evident vanity" .)
