This paper aims to present the modelling process and models of Turiec River hydronymy. Turiec is a river in northern Slovakia. The term A1 model is used to denote a model mapping the content aspect of a hydronym. It contains a functional member with a semantic attribute signalling the type of onymic relation and functional members expressing other semantic attributes. Hydronymic models are categorized according to the number of functional members into one-membered, two-membered, and three-membered models. Two-membered models are most frequent, especially models expressing a relation to a place and describing a specific feature. Models using flora and fauna for honorification purposes also occur. The presented types of models, categorized according to the number of functional members and to the identified semantic characteristics of functional members, co-create the paradigm of hydronymic modelling.
