polypersonal

Polypersonal refers to a linguistic phenomenon in which a single verb form bears markers that index multiple participants of an event—typically including the subject and one or more objects, and sometimes indirect objects or benefactive/possessive arguments. In languages with polypersonal agreement, the verb encodes the person (and often number) of several core arguments at once, rather than marking only the subject as in many familiar languages.

Morphology and syntax: Polypersonal marking can appear as prefixes, suffixes, infixes, or clitics integrated into the verb. The resulting verbal paradigm may include distinct markers for first, second, and third person across multiple arguments. Some systems attach object or indirect-object information directly to the verb, while others use clitic pronouns that are phonologically dependent but syntactically integrated with the verb. The exact set of marked arguments and the way they combine vary across languages.

Distribution and variation: Polypersonal agreement is a cross-linguistic typological feature found in a number of language families. It is particularly well documented in some Berber languages (Tamazight varieties), certain Caucasian languages, and various Indigenous languages of the Americas. Across languages, the degree of poly-personal indexing, the set of arguments that can be encoded, and the interaction with word order or ergative patterns differ substantially.

Typology and implications: Polypersonal systems frequently interact with broader morphosyntactic alignment and discourse-pragmatic factors, influencing how arguments are expressed and how information is structured in a clause. The study of polypersonal agreement sheds light on the diversity of verb morphology and the ways languages economize or emphasize participant information within a single word.
