<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">self-effacing</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for modest that I've seen before include "Inexpensive" , "Unassuming; limited" , "Not vain, rather shy" , "Avoiding indecency; unassuming" , "Bashful" .)
