The aim of this paper is to provide an account for the distribution of the three adnominal case particles: -no, -nga and -na in the Mitsukaido dialect. As a result of our survey we have reached the conclusion that the distribution of the two particles -nga and -na is semantically determined by two factors, the inherent features of N1 and the semantic relation between N1- N2. Namely, -nga is used when N1 has a high degree of animacy and the relation N1-N2 is in the semantic sphere of possession. It should be noticed that in order to account for the distribution of the particle -nga, animacy should be viewed not as a binary feature but as a scalar value. The particle -na is used when N1 belongs to the category of nouns expressing position, such as: mugo:, me, attsji, kottsji, etc. and the relation between N1-N2 is location-located object. Unlike-nga and -na, the distribution of -no is not subject to any semantic restriction, its unique role being that of formal marker of the adnominal modification relation.
Like -no in Standard Japanese, the forms -no and -nga in the Mitsukaido dialect also appear as nominalizers (juntaijoshi). The distribution of the nominalizers -no and -nga appears to be determined by the categorial features of the preceding material. Namely, -no is used to nominalize verbal elements (verb phrases, adjectival phrases), whilenga appears in contexts where the preceding material is nominal. The form - na does not have nominalizing function.
