When the phonological patterning of accentedness and accent location is examined across dialects of Japanese, three types of behavior are found. In some cases, no words, of any syntactic category, are permitted to have a phonological contrast with respect to a particular accent-related structure. In other cases, words of all (lexical) categories have the accent-related contrast in question.
... [Show full abstract] Finally, there are cases where nouns, and only nouns, are permitted to contrast with respect to accent. A fourth logical possibility is not found: a dialect in which words of a certain category are permitted to show an accent-related phonological contrast, but nouns are not. To account for this typology of accent-related behavior, I make the following proposal (in the framework of Optimality Theory; see section 2.2): In addition to markedness constraints and general faithfulness constraints, the grammar also contains faithfulness constraints that are specific to nouns. The constraint set therefore allows exactly three classes of grammars to be generated. In grammars where accent-related markedness constraints are highest ranked, no accent-related phonological contrast is
