# betababel: You haven't defined the language polutonikogreek yet

For many years I used the package betababel to combine Latin and Greek letters in one document, but since version 2014.20141024-1 of texlive-lang-greek, the simple example

\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{betababel}

\begin{document}
\bcode{lo/gos}
\end{document}


(which worked with the previous version) produces this error when compiling with pdflatex:

Package babel Error: You haven't defined the language polutonikogreek yet.


Any ideas how to solve this?

• Welcome to TeX.SX! Nice question and thanks for the MWE. Maybe, you send a notice to the maintainer of betababel. Jan 20, 2015 at 12:32

I do not know if this runs into some clashes, but as betababel loads babel as well, it should be safe to do:

% arara: pdflatex

\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[polutonikogreek, ngerman]{babel}
\usepackage[ngerman]{betababel}

\begin{document}
\bcode{lo/gos}
\end{document}


As written in your output, the babel option polutonikogreek was missing. As betababel does not offer this option, just load it via the original babel.

• The manual for betababel says explicitly not to do this.

• @cfr I fear the betababel documentation is outdated: betababel was last updated 2005, while babel-greek and the babel kernel were last updated 2016. Oct 31, 2016 at 19:11
• @wicho The problem is that betababel wants to load Babel with options. If you load Babel first, that isn't possible.

The packages betababel does not seem to have received updates in the last decade(s). I strongly discourage the use of it. (I could not get it up and running on a TexLive 2021 installation.)

I recommend to directly write Greek in your Tex file. Use Greek stickers on your keyboard and select a Greek layout in your operating system.

An example would look like

\documentclass{article}

% Set the font (output) encodings
\usepackage[T1]{fontenc}

% \usepackage[utf8]{inputenc} is no longer required (since 2018)

% Greek-specific commands
\usepackage[greek,english]{babel}

\begin{document}
\tableofcontents

\begin{abstract}
\textgreek{Αυτή είναι μια σύντομη περιγραφή του θέματος}
\end{abstract}

Latin text can also be added to the document.
\end{document}
