スラヴ諸語における母音交替 : 音韻現象の生産性の観点から

This paper discusses vowel alternations among Slavic languages. While some processes exceptionlessly occur under certain phonological conditions, others show exceptions. Among the latter type of alternations, some are productive to such an extent that they can extend their range even to loanwords, whereas others are restricted to several lexical items. In previous phonological studies, lexical exceptions have been accounted for mainly by two approaches: special underlying representation and lexical stratification. This paper proposes that one or the other of these approaches should be adopted depending on the productivity of the given sound alternations. In the current analysis, productive processes are accounted for by lexical stratification and certain faithfulness constraints specific to each lexical stratum. Lexically restrictive phenomena, in contrast, are explained by assuming underspecification for the alternating phonological categories in the underlying forms.言語
