In some languages, there is no distinction between adjectives (defined semantically) and nouns in terms of their morphological behavior, while other languages treat the two categories as distinct word classes. To analyze a language in terms of this parameter, it is necessary to consider an adjective in attributive position (modifying a noun, rather than replacing a noun).

Types:

AdjNotNMorph: Attributive adjectives are distinct from nouns in their morphological behavior; while nouns show inflection for categories such as number, case, and gender, attributive adjectives do not.

Adj=NMorph: Attributive adjectives are identical to nouns in their morphological behavior; both nouns and attributive show inflection for categories such as number, case, and gender.

Adj=NNoMorph: Attributive adjectives are identical to nouns in their morphological behavior; neither nouns nor attributive adjectives show inflection for categories such as number, case, and gender.

When a language displays more than one type, multiple values can be listed. If one type is structurally dominant, a slash (/) can separate the values, with the dominant value appearing first; if neither is dominant, they are listed with an ampersand (&) separating the values.
