I tried the first and second solution proposed here Change the word "Chapter" to something else . But once I replaced book by memoir class. It triggered an error. The first solution was completely broken while the second one, while intact, triggered the following message:
/usr/local/texlive/2014/texmf-dist/tex/latex/fancyhdr/fancyhdr.sty, line 302
LaTeX Error: Command \footruleskip already defined.
Or name \end... illegal, see p.192 of the manual.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.302 ...and{\footruleskip}{.3\normalbaselineskip}
Your command was ignored.
Type I <command> <return> to replace it with another command,
or <return> to continue without it.
Here is the code based off the second solution:
\documentclass{memoir}
\usepackage{fancyhdr}
\makeatletter
\renewcommand{\@chapapp}{Step}
\makeatother
\begin{document}
\chapter{How to sow seeds}
\end{document}
memoirpackage emulates a lot of other packages or has built in support forgeometryand other macros. And it provides its ownpageheader/footer commands. Perhaps there's no need to usefancyhdrhere at all. – Jan 14 '16 at 20:31\chaptername, note: if you are usingbabelas well then the any change to\chapternameshould go into\captions<language>via\addto\captions<language>{...}– daleif Jan 14 '16 at 21:44
