Information flow
From Wikipedia, the free encyclopedia
- For other meanings of equivocation, see Information flow (disambiguation).
In discourse-based grammatical theory, information flow is any tracking of referential information by speakers. Information flow affects grammatical structures such as
- word order (topic, focus, and afterthought constructions)
- active, passive, or middle voice
- choice of deixis, such as articles; proximal, medial, and distal deictics such as Spanish este, ese, aquel, are often determined by the familiarity of a referent as much as by physical distance
- overtness of information, such as whether an argument of a verb is indicated by a lexical noun phrase, a pronoun, or not mentioned at all.
