Gray, for one (7)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">gray for one</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 elegist that I've seen before include "Kind of writer" , "Writer of mournful verse" , "Poet, e.g. Gray" , "Writer of reflective poems" , "bemoaning linesman" .)
