nafnorðsvísis

Nafnorðsvísis is a theoretical concept in linguistic typology used to describe how noun phrases encode grammatical information such as number, definiteness, and case within a language. The term is primarily discussed in Icelandic-language grammar discussions and has not achieved broad acceptance in mainstream syntax literature.

The name combines nafnorð, meaning "noun," with vísis, a scholarly coinage element indicating an indicator or system. As such, nafnorðsvísis refers to a system or set of rules governing how a noun phrase is constructed and how its internal elements relate to the head noun.

Core ideas of the concept include the structure of a noun phrase as a head noun with dependent modifiers such as determiners, adjectives, and numerals; the agreement of these modifiers with the head in gender, number, and sometimes case; and the rules that determine word order and marking in definite versus indefinite contexts.

In languages with rich agreement (such as Icelandic), the noun phrase can exhibit multiple inflectional endings that signal definiteness and case. Nafnorðsvísis provides a comparative framework to analyze these patterns across languages, highlighting how different systems realize similar functional distinctions within noun phrases.

Status and reception: The term is not widely established in standard grammars; it is frequently treated as a theoretical locus for discussion rather than as a canonical label. When used, it is typically as a descriptive placeholder rather than a prescriptive analysis.
