(Un)markedness of trills: the case of Slavic r-palatalisation

This paper evaluates trills [r] and their palatalized counterparts [rj] from the point of view of markedness. It is argued that [r]s are unmarked sounds in comparison to [r]s which follows from the examination of the following parameters: (a) frequency of occurrence, (b) articulatory and aerodynamic characteristics, (c) perceptual features, (d) emergence in the process of language acquisition, (e) stability from a diachronic point of view, (f) phonotactic distribution, and (g) implications. Several markedness aspects of [r]s and [rj] are analyzed on the basis of Slavic languages which offer excellent material for the evaluation of trills. Their phonetic characteristics incorporated into phonetically grounded constraints are employed for a phonological OT-analysis of r-palatalization in two selected languages: Polish and Czech.
