Noun classes

There are 17 classes for count nouns in Mufian, plus two extra classes, i.e. proper names and place names. Noun classes are expressed in noun suffixes, adjective suffixes, and verb prefixes.
Although Southern Arapesh has more than a dozen noun classes, only four noun classes are determined by semantics, while the other noun classes are determined phonologically using the final root segment. The four semantically determined noun classes are:

class 16: male human referents
class 8: female human referents
class 5: human referents of unspecified sex
class 6: human referents of unspecified sex

The membership of the other twelve classes is determined phonologically, by the final segment of the root, as in the Lower Sepik languages.
