Code:
\documentclass[paper=3.5cm:5cm]{scrbook}
\usepackage{german}
\usepackage[german]{babel}
\usepackage[utf8]{inputenc}
\begin{document}
Andere übertragen das am besten den Geschwistern.
\end{document}
Output:

Hyphenation for these standard German words is incorrect. I know that we can
specify hyphenation manually, e.g. übertra\-gen, but that makes source code
less readable, and it would be tedious for an entire book.
How do I tell LaTeX to use proper hyphenation?
Desired hyphenation is for a German text authored between 1914 and 1918.
