I use the acronym package for creating footnotes. Those I usually mark with \ac{MyWord} and if plural then \acp{MyWord}. To import the package, I use:

\usepackage[footnote, printonlyused]{acronym}

My problem is in the footnote when making use of \acp. It ads an "s" at the end of the sentence and I would like to avoid that.



Creates in my case the footnote: Language used in the web.


creates in my case the footnote: Language used in the web.s

How can I get rid of the "s" at the end of the footnote created by \acp{HTML}?

Edit 1 - code example:

\usepackage[footnote, printonlyused]{acronym}
    \section{Test Chapter}
        This is a Test for showing the error. No error with \ac{HTML} using ac, but an unwanted "s" is added with \acp{Action} when using acp.
        \acro{HTML}{Language used in the web.}
        \acro{Action}{Used within the math function as a parameter.}
  • Can you provide a full example, please?

    I am very confused reading the question. An acronym is something like CD (compact disc). THe long form should not be a complete sentence. And why do you have a plural form of HTML?

  • @Johannes_B: I think, it should be more of a glossary, perhaps? But a plural of HTML seems weird indeed

  • HTML is just an example. I write in German where it makes sense to have an "s" for plural at the end of a word, but not within the footnote. I added an edit with a code example.

    @ChristianHupfer I see the extra s :-p But i think using acronym is the wrong approach here and glossaries should be used.

You need to redefine the plural form with\acrodefplural

    \acro{HTML}{Hyper Text Markup Language}
    \acrodefplural{HTML}[HTML]{Hyper Text Markup Languages}
  • Totally confused myself. But this works. Though you need to build it at least twice.

  • Thanks for the answer. I couldn't get it running with \newacroplural, but I solved it using \acrodefplural{Action}[Actions]{Action is used within the math function as a parameter.} in the same way as in your example. It works now even though I have redundant double text. Better dirty than not at all.

  • so I change it to acrodefplural. But I'm not sure, if acronym is the right package. Wouldn't glossaries be better?

  • Maybe glossaries is the better package, but I couldn't get it working using xetex. For now this workaround will have to do. I might start a new post for glossaries.

  • @Socrates: Do you have makeglossaries as well?
