portatiivsust

Portatiivsust is a theoretical term in linguistics used to describe the degree to which a language encodes portativity—the property of marking actions with respect to instrumentality or portable means by which they are performed. The concept covers both morphological and syntactic strategies that indicate how an action is carried out, including whether it is performed with a portable tool or under the agency of a portable actor.

Origin and usage

The term draws on the root port- meaning carry and the suffix -ust to denote a state or quality in some linguistic analyses. It is employed primarily in typological and theoretical contexts to describe a proposed dimension of morphosyntax that complements voice, mood, and aspect. Portatiivsust is typically discussed as a property that languages may or may not encode explicitly, rather than as a universal category found in every language.

Typology

Scholars distinguish a range of portatiivsust levels, from zero (no explicit portativity) to high (frequent and productive portative marking). Strategies include instrumental case markers, dedicated portative or instrumental mood markers, and periphrastic constructions that convey portability. Some languages rely on lexical phrases to express portativity rather than dedicated grammatical means, making cross-linguistic comparison challenging.

Relevance and debate

Portatiivsust is evaluated for its usefulness in accounting for variation in how languages encode the relationship between action and means. Proponents argue that it clarifies patterns of instrumentality and action structure; critics warn that it can overextend the category or blur distinctions with related concepts like voice and aspect. Methodologically, assessment often involves typological surveys, controlled elicitation, and historical reconstruction.
