# Two plural forms for acronyms

Is it possible to have more than one plural form for acronyms?

I want to use the following german term for revision/version control system:

VVS for Versionsverwaltungssystem

the normal plural would be Versionsverwaltungssysteme

But I would also use it like this: ...mit verteilten Versionsverwaltungssystemen (n at the end)

How may I do that right with latex? :)

I would think you should know when to use the dative form. In these cases you could simply use \aclp{VVS}n (supposing you're using the acronym package). –  clemens Jul 6 '12 at 15:34
Sure, that would be my workaround/fix if it's not (AFAIK it is not) supported by the acronym package –  kmindi Jul 6 '12 at 22:52
I'd say that's the way to go. You can add only one form for the plural commands like \acp. acronym can't possibly add options for all cases. Suppose you want Versionsverwaltungssystems (genitive singular), too. And there surely are languages which need even more. So acronym only covers the basic and most common additional form: one plural for each acronym. –  clemens Jul 7 '12 at 16:24

I’d recommend taking a look at the glossaries package. When defining an acronym you have six user-defined keys at your disposal which you can use for storing any additional information. Minimal example:

%% Document generation:
%% \$ pdflatex example && makeglossaries example && pdflatex example

\documentclass[naustrian]{article}

\usepackage{babel}

\usepackage[acronym]{glossaries}

\makeglossaries

\newacronym[
longplural={Versionsverwaltungssysteme},
user1={Versionsverwaltungssystems},
user2={Versionsverwaltungssystemen}
]{VVS}{VVS}{Versionsverwaltungssystem}

\let\acrlonggen\glsuseri
\let\acrlongpldat\glsuserii

\begin{document}

\noindent
das \acrlong{VVS}      \\
des \acrlonggen{VVS}   \\
die \acrlongpl{VVS}    \\
den \acrlongpldat{VVS}

\printglossary[type=acronym]

\end{document}


The resulting output is:
