Borrowed from German Wisent in the 19th century. The native word, Middle Dutch wesende, from Old Dutch *wisent (in the placename Wisenthurst) had by then long been obsolete due to the medieval extinction of the species in Western Europe.
Breeding programmes and the establishment of several viable herds in the Netherlands has since the early 21st century rendered the word familiar to a broader audience; it was previously mostly restricted to a learned context.
