A theory of consonantal interaction

Co-occurrence restrictions on word-initial consonant clusters are traditionally viewed as a consequence of the relative sonority of both members of the CC. In the first part of this paper, I aim to show that the reasoning underlying this approach is circular. The observation that sonority does increase in word-initial clusters is relabelled explanation in saying that sonority must increase. Since the crucial part of this circular argumentation is expressed by a constraint (“sonority must increase within word-initial clusters”), I address the more general issue of constraints in linguistic theory. In the second part of the paper, I propose a constraint-free theory where restrictions on word-initial clusters follow from the interaction of more general principles. The main principles I draw on are Government-Licensing (Charette, 1990), segmental complexity (Harris, 1990) and a strict CVCV syllable-structure (Lowenstamm, 1996). None of these devices makes special reference to wordinitial clusters. Since word-initial restrictions crucially depend on idiosyncratic properties of the consonants involved, I also investigate the internal structure of consonants. In the representations I introduce, the set of observations commonly subsumed under the label sonority is assigned no phonological status. Rather, it is shown to be a function of known phonological primitives. Finally,
