I'm Malay user. I want to rename the theorem tag in Beamer. Does anyone know how to do it? When the document class is article or book, I can simply modify the preamble as follows:

\newenvironment{proof}[1][Bukti]{\noindent\textbf{#1.} }{\ \rule{0.5em}{0.5em}}

However, the above things does not work in Beamer. So, does anyone know how to do it?

beamer uses translator to translate environment names and some other words. It uses some .dict files which you can translate to your language and start to use. Look at manual's section Translating strings. Here you have a little example.



I will translate \structure{\translate[to=spanish]{theorem}} but not theorem

enter image description here

Another option would be to use \begin{block}{Korolari} ... \end{block}.

Update: A better and more detailed explanation can be found in Beamer newtheorem translation

    I tried to use \deftranslation with Danish, which did not just work. The problem was that I needed to spell Danish with a capital D. E.g. \deftranslation[to=Danish]{Theorem}{Sætning}.

  • Using \uselanguage{Spanish} and \languagepath{Spanish} will automatically load translations -- observe the upper case! Jul 28, 2022 at 8:37

beamer already provides theorem environments: theorem, corollary, definition, definitions, fact, example, examples, and lemma. You can disable them by a class option, then you can define your own environments without those name conflicts. For proof use \renewenvironment, as it's also predefined.

So you could use beamer environments if you would like to benefit from beamer features, using beamer's syntax, or define your own with numbering and formatting as you like.

\renewenvironment{proof}[1][Bukti]{\noindent\textbf{#1.} }{\ \rule{0.5em}{0.5em}}
