The philologist Friedrich Seiler examines in his four-volume work the words borrowed from foreign languages and translated into German. This approach provides insights into the historical development of the German language and simultaneously reveals the various cultural influences that have shaped the German-speaking world. The fourth volume deals with loanwords from the modern era and continues the third volume. Seiler considers foreign language influences on public life, particularly in the military and state affairs. This is an unaltered reprint of the original edition from 1912, which is long out of print.
