# changing name of “nomenclature” not working in lyx

why could it be that the suggested command won't work in Lyx? I am using the "Book (standard) class". Thank you, everyone!

\renewcommand\nomname{New Name for Nomenclature}


edit:

I have to enter the command in the Lyx' document settings in the preamble. I actually did not use the [\printnomenclature] command, but it's printed further down in the document.

once I convert it into a normal latex file, I can see that the lyx-generated nomenclature - entries are above my commands. (As Phelype suggested.) I don't know how to change this in Lyx, though.

• Welcome to TeX.SX! This should work as long as you use it before \printnomenclature. If you are using that command (either version works) before the \printnomenclature and it still doesn't work, then please show us a minimal working example (MWE) of your document. – Phelype Oleinik Mar 14 '19 at 14:44

Okay, I was finally able to solve the issue. Lyx apparently adds an automatic command regarding the name of the nomenclature after the preamble written by the user.

In order to change the name of the "nomenclature" you have to add the command

\renewcommand\nomname{New Name}


as a direct TeX-Code directly in the main document. In order to add it to the toc, you also have to include

\def\nompreamble{\addcontentsline{toc}{chapter}{\nomname}\markboth{\nomname}{\nomname}}


in the preamble.
