pluralisoiva

Pluralisoiva is a linguistic term used in typology to describe a class of pluralizing operations—morphological, syntactic, or both—that mark plurality on a word or phrase. Etymologically, the word is formed from Finnish pluralisointi (pluralisation) and the participial suffix -iva, yielding an adjective meaning “pluralising.” The concept is used as a descriptive label rather than a single universal mechanism, reflecting the diversity of how languages encode number.

In practice, pluralisoiva can refer to several strategies. These include affixal pluralizers (suffixes, prefixes, or infixes attached to nouns or pronouns to indicate plurality); stem-modifying devices such as vowel alternations or reduplication that accompany plurality; and periphrastic or clausal strategies in which numerals, quantifiers, or demonstratives trigger or accompany plural agreement in the surrounding phrase.

Some languages employ a dedicated pluraliser morpheme that co-occurs with determiners or adjectives; others rely on broader numeral phrases or determiner-noun constructions to convey plurality. In many systems, pluralisoiva interacts with other number features, such as dual or collective plurality, and may align with agreement on adjectives and verbs.

Because pluralisoiva is a broad, cross-linguistic concept rather than a single concrete morpheme, its exact form, position, and phonology vary widely across languages. It is most often discussed in typological surveys of plural marking rather than in the grammars of individual languages.
