Exploring the technical languages that display dynamism in their word-formation, the present paper focuses on the contemporary state of Czech geocaching terminology, i.e., mainly newly incorporated terms, still not fully adapted into the Czech language. It briefly outlines how the currently used borrowings function in the Czech geocaching vernacular and their level of adaptation to the Czech orthographic, phonological and morphological systems. This article will aim to show how these new lexical items are being adapted to the Czech language on different levels of the three language systems mentioned. The vocabulary under investigation was collected from the Czech newspaper magazine Víkend Dnes issued on 14 July 2018.
