Nouns in Meyah are divided into two types: alienable and inalienable, the latter of which includes terms for body parts and kinship relations, and are obligatorily marked for possessor.

For inanimate nouns, a plurality may be indicated by certain modifiers such as: modhouseofokoumanymod ofokouhouse manymodhouseefagaCLForgomuthreemod efaga orgomuhouse CLF threeKinship terms, as inalienable nouns, share the same possessor prefixes as body parts and verb stems, however, they differ in the singular possessive prefixes.

On verbs and other inalienable nouns, the third person singular possessive prefix is normally unmarked, but kinship terms use the same prefix as the first person plural exclusive, me-.

Terms for important kinship relations have divergent morphology, like the lack of a first-person singular possessive prefix for father akeina and mother ameina, which are also used to refer to father and mothers' brothers respectively.

There are six classes of nouns, which are differentiated on the basis of their classifier when they are modified by a numeral.
