I have a large document with lector notes. And each lector I'm separating by \part. I would like to change the default numbering text from "part" to "Lecture".
Example:
\documentclass[a4paper,oneside,article]{memoir}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[danish]{babel}
\usepackage{lmodern}
\usepackage{fullpage}
\usepackage[numbers]{natbib}
\usepackage{mathtools}
\usepackage{graphicx}
\graphicspath{{Figures/}}
\begin{document}
\frontmatter
\input{titlingpage.tex}
\tableofcontents
\mainmatter
\part{Teknologiske forudsigelser}
\bibliographystyle{plainnat}
\bibliography{IFVT}
\end{document}

The language is Danish.
And as I said, I'm would like to change "Del" with "Grupperegning".
\addto\captionsdanish{\renewcommand*{\partname}{Grupperegning}}. See http://tex.stackexchange.com/questions/82993/how-to-change-the-name-of-document-elements-like-figure-contents-bibliogr – lockstep Feb 12 '13 at 10:27
