Pabappa nouns

Pabappa has nouns.

Number

Pabappa does not have a grammatical category for number in the sense that plural nouns take plural adjectives and plural verbs or anything of the sort. Most nouns are lexically unmarked for number, meaning that possimi can mean "flag" or "flags" equally often and neither use is incorrect. A few nouns can only refer to a singular, mostly words for body parts and familial relations. Many of the body part words have suppletive dual and/or plural forms.

The vast majority of nouns, however, are unmarked for number, and take the suffix -pum to specifically indicate a plural. -Pum is not normally used when a number modifier such as pibi "four" is specified; if it were, it would indicate four "pluralities", not four individuals. This suffix is cognate to the Poswa -bum suffix and itself becomes -bum after a noun ending in a vowel. The Poswa -by suffix no longer exists in Pabappa, and even those words in which it had become fossilized as -p now generally behave as singulars and take the additional suffix -pum to form the plural.

Body parts

Some words for body parts in Pabappa have suppletive dual or plural forms. Most of these are words for pairs. For example, pep means one hand. Pobop, the dual form, indicates both of one person's hands; and the plural form peples indicates any number of hands greater than one, including two, regardless of whom they belong to. Thus two people shaking hands are touching their peples, but one person pulling on a tow chain with both of his hands is straining his pobop.
