Later on in this chapter, while discussing the lenitiontheory called The Coda Mirror (Ségéral and Scheer 1999), we shallsee that audible nuclei are guaranteed the right to both govern and license.The representation in (38b) is exploited to cover the forms under(37b). At first sight, it may seem problematic to postulate two representationsfor a single structure. Recall, however, that the same move wasrequired during the discussion concerning initial #TR clusters. 27 It wasdemonstrated (see section 2.2) that although the form gra ‘play, nom.sg.’possesses an alternating vowel which surfaces in the related form, i.e.gier ‘play, gen.pl.’, the alternation is not handled by PG alone, but actuallyby two different mechanisms. The (un)vocalised character of the prefixbetrays the status of the root-initial consonant cluster. Thus, the [gr]cluster in zgraæ ‘synchronise’ contracts the IG relation, while in rozegraæ‘play out’ the same cluster is separated by the properly governed emptynucleus. A similar situation is encountered in roots possessing trappedconsonants (37a, b) above. Trapped consonants can dispense government,but also can serve as the licensor of consonantal relations giving theforms in (37b).While discussing Polish word-initial RT clusters (section 2.3), we haveseen that most such sequences are spurious. This means that someof the #RT clusters are broken up by an alternating vowel, while someothers betray the presence of the properly governed nucleus as they vocalisethe prefix vowel. At the end of section 2.3 we have been left witha small group of #RT clusters, which are repeated under (39) for convenience.27The more serious problem, however, is the lack of the prediction concerningthe ability of trapped consonants to license the IG domains. In other words, why is itnot possible for the [dr] cluster in (38a) to contract the IG relation? It seems thathere we are not dealing with ‘pure’ phonology. We leave the question open for furtherstudy.6 Polish...
