Lexicographer \Lex`i*cog"ra*pher\ (-[i^]*k[o^]g"r[.a]*f[~e]r),
   n. [Gr. lexikogra`fos; lexiko`n dictionary + gra`fein to
   write: cf. F. lexicographe. See {Lexicon}.]
   The author or compiler of a lexicon or dictionary.

         Every other author may aspire to praise; the
         lexicographer can only hope to escape reproach; and
         even this negative recompense has been yet granted to
         very few.                                --Johnson.
