Word derived from a name (6)
I believe the answer is:
eponym
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">word derived from a name</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 eponym that I've seen before include "someone giving a name" , "Distinguishing title; derived name" , "Word derived from person's name or placename" , "a mackintosh, for instance" , "eg 'Jane Eyre'" .)
