From: Przemyslaw Pawelec The Trapped Sonorants in Polish The paper addresses the problem of the so called Trapped Sonorants in Polish, i.e. consonantal sonorants that appear in an onset between two consonants of lower sonority, as in e.g. krwi [krf'i] 'blood' and brwi [brv'i] 'brow' (both gen.sg). It is argued that they should not be treated on a par with other types of sonorants violating the Sonority Sequencing Generalization (SSG) in Polish. The argument is supported by a new observation about the structure of the offending onset clusters. The paper refers to a recent study of trapped sonorants in Rubach (1997), where a comparison is made of how two different theories, a derivational theory (DT) and the Optimality Theory (OT), handle the problem of sonorants that violate the SSG. When OT is found to be in some ways superior to DT, but at the same time incapable of accounting for the phenomenon of trapped sonorants, Rubach (1997) offers a new solution: Derivational Optimality Theory (DOT), which is a modified version of OT. The revision does not come without a cost, though - the introduction of a derivational step into OT undermines one of its basic tenets. The discussion in the present paper begins with the observation that in Polish there are four kinds of environment in which consonantal sonorants may occur with what appears to be an SSG violation: a) word-initial, e.g. rtec 'mercury', lsnic 'shine'; sonorants in this position are not transparent to Voice Assimilation, i.e. in Warsaw Polish there is no Voicing across word boundary before them. b) word-final, e.g. lotr 'villain', organizm 'organism', which are transparent to Voice Assimilation. c) word-medial between two syllable nuclei (and not adjacent to any of them, naturally) are also transparent to Voice Assimilation. d) in the onset of a word-initial syllable, between two consonants of smaller sonority; in this position the so called trapped sonorants are transparent to Voice Assimilation. In the DT analysis in Rubach (1997) sonorants in all four kinds of context are assumed to be extrametrical, i.e. they do not belong to any syllable and thus do not violate the SSG. Technically, they are not linked to the syllable node, but directly to the PW node. At the same time good use is made of the opportunities offered by the derivation: the difference in transparency between type (a) on the one hand and types (b), (c), (d) on the other is shown to be due to the difference in the stage of prosodic licensing, and, consequently, voice specification of sonorants: before the application of Final Devoicing and Voice Assimilation (Delinking and Spread) for type (a), and after it for types (b,c,d). As this is not available in OT (there is no derivation, so there is no way of distinguishing between a non-transparent sonorant in (a) and transparent sonorants in (b,c,d) by means of derivational stages) the desired effect is obtained by the appropriate ranking of constraints. In the OT analysis in Rubach (1997) word-initial sonorants (a) are forced into a syllable (a violation of the SSG), while final and medial sonorants (b and c) remain extrasyllabic, and are linked to PW node (a violation of Strict Layer). Unfortunately, type (d) poses a problem for this kind of analysis. Trapped sonorants are transparent, so they should be extrasyllabic and linked to PW node, like in types (b) and (c), but for reasons independent of the DT/OT distinction it is not possible: association lines would have to cross, which is not permitted by the principles of Autosegmental Phonology, a theory of representation that is assumed in both DT and OT. This leads the author to the postulation of a new theory, DOT, where the constraints are reranked after a derivational step. The argument rests on the assumption that there is nothing special about type (d), so no constraints that would refer specifically to (d) are justified. Thus it is argued that (d) should be accounted for by means of the reranking of the same constraints which account for types (a), (b) and (c), and this in turn is done by means of a derivational step. In this paper we will try to demonstrate that trapped sonorants in (d), in fact are different: their structure is very specific, strongly restricted, and what is more, it is contrary to what should be expected. Trapped sonorants in certain respects do not behave like transparent sonorants in (b) and (c), but like obstruents which impose stronger distributional restrictions on neighbouring sounds than "true" obstruents do in Polish. A new observation about the structure of the offending onset clusters is made and alternative solutions for a derivational theory and for the Optimality Theory are suggested.
