I believe the answer is:
rossini
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">opera composer</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 rossini that I've seen before include "Staff writer" , "Composer born 29 Feb 1792" , "Largo al factotum composer" , "Composer of the opera William Tell, d. 1868" , "He composed operas" .)
