nomenform

Nomenform is a linguistic term used to describe the set of noun-related forms that a language uses for a given noun. It encompasses the various inflected forms a noun can take to express grammatical features such as number, case, and sometimes gender, as well as any determiner or definiteness markers that accompany the noun. The exact scope of nomenform can vary between grammars: some define it narrowly as the inflected noun forms themselves, while others include the surrounding determiner-noun combinations that participate in marking function and syntax.

In analytic languages with limited noun morphology, nomenforms are often few. For English, the primary noun

The nomenform system is central to nominal morphology and declension paradigms. Linguists describe noun classes or

Examples illustrate the range of nomenforms: German nouns show nominative singular Hund and nominative plural Hunde;
