indefiniteplural

Indefinite plural is a term in linguistics describing a plural noun phrase whose reference is not specifically identified or known. It contrasts with definite plural forms, where the referent is identifiable or previously established in discourse (for example, the dogs versus dogs in general).

Realizations of indefinite plural vary across languages. Some languages mark indefiniteness with explicit determiners or quantifiers, such as some, several, or unos/unas; others rely on the bare plural to convey indefiniteness or a generic meaning, depending on context. In English, bare plurals like dogs can express indefinite or generic reference (Dogs are friendly), while determiner phrases such as some dogs or a few dogs clearly signal indefiniteness.

Cross-linguistic patterns show diversity. In German, bare plurals can be used for generic statements (Hunde sind freundlich), and explicit indefiniteness is conveyed with forms like einige Hunde (some dogs). Spanish and Portuguese express indefiniteness in the plural with unos/as or algunos, in contrast to definite forms like los perros or las mascotas. Other languages lacking articles may rely on numerals, classifiers, or context to mark indefinite plurality. In some languages, indefiniteness in the plural is distinguished by dedicated markers or noun-class systems, while in others there is no separate morphological indication beyond the determiner or contextual cues.

In linguistic typology, indefinite plural intersects with concepts of definiteness, referentiality, and number marking. It supports generic statements, unbounded references, and discourse-level indefiniteness, with interpretation shaped by context, world knowledge, and the grammatical system of a language.
