O idiomatickém charakteru pojmenování v mutační kategorii

In Dokulil (1978, 1986), the idiomaticity of a naming unit is understood as a discrepancy between the structural and lexical meanings of newly coined words. This discrepancy is viewed as a characteristic feature of new naming units formed within the mutational onomasiological category. The paper aims to describe the nature of this discrepancy using an onomasiological model primarily based on Štekauer (1998) and Grzega (2007) with its origins in Dokulil’s theory. The model comprises three main levels, namely perceptual, onomasiological, and onomatological, and at all three levels there are aspects that contribute to the idiomaticity of the resulting naming unit. At the perceptual level it is the metonymical character of the salient features; at the onomasiological level it is mainly the extent to which individual features find lexical expression, and at the onomatological level it is predominantly the incorporation of metaphor and metonymy.
