Each less known addition to the collection of authentic Livonian language materials is very valuable, and a small contribution can also be made by Juris Plāķis’ publication about Latvian, i.e., Courland toponyms, among which Livonian ones can be found as well. This collection includes toponyms collected by J. Plāķis himself, toponyms from Augusts Bīlenšteins’ onomastic materials, as well as toponyms which have been sent in to the Folklore depository by pupils from different parishes. This article goes through oronyms (hill names).
