<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">self</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for ego that I've seen before include "(Person's) sense of self-esteem" , "Vowel to disappear, < say another" , "One's self image" , "Conscious self" , "One's sense of self-importance" .)
