multinouns

Multinouns are a proposed category of nouns that exhibit cross-cutting grammatical behavior, allowing a single form to function in multiple nominal patterns depending on context. The idea is to describe nouns whose semantics and syntax can shift between distinct subtypes, such as countable versus mass readings, or multiple pluralization and determiner patterns, within the same language.

Key features of multinouns include morphosyntactic versatility, semantic polyfunction, and context-dependent determiner use. Some multinouns may take different plural forms or singular-plural coordination depending on sense, while others can be treated as both count nouns and mass nouns. This flexibility often arises in words that refer to substances, collections, or classes of things, where the intended interpretation is guided by context, determiner, or accompanying qualifiers.

Illustrative examples help show the concept. The word data historically exists as a plural of datum, but in contemporary English it is frequently used as a mass noun with a singular agreement: the data shows. The noun waters can refer to bodies of water (The river’s waters were calm) or to streams of water in a broader sense (the Waters of the Nile). The word fishes is used to indicate multiple fish, often when referring to multiple species, whereas fish generally denotes individual fish or fish as a collective group in ordinary usage. These cases illustrate how a single form can encode different plural patterns or readings, depending on sense and context.

In linguistics, multinouns are primarily a descriptive tool for analyzing polysemy, pluralization, and determiner patterns rather than a formal grammatical class. They highlight how language users negotiate meaning and grammatical agreement in real-world use.
