@jhilden There are indeed exactly theses parallels from German to Dutch. Words that sound old and from the past in one language, commonly used in another.
Siechenhaus (German for Infirmary, no longer used)
Ziekenhuis (Dutch for Hospital)
Or in my favorite example, the meaning is reversed.
Seltsam (German for Strange)
Zeldzaam (Dutch for Rare)
vs
Rar (German for Rare)
Raar (Dutch for Strange)
An old friend studies comparative language science. But specialized in eastern languages.
