“…For example, the stance of certainty is widely marked through factive predicates, determiners, cleft constructions, and other presupposing structures (Levinson, 1983;Givon, 1989), whereas uncertainty is widely marked through modals, rising intonation, and interrogative constructions (Lakoff, 1972). Possible universals in the marking of affective intensity include the use of vowel lengthening, modulation of volume and pace of delivery, use of a morphologically marked form (e.g., use of plural marking for a single referent, use of demonstrative pronoun to refer to a person rather than a thing), and code switching (Stankiewicz, 1964;Duranti, 1984;Ochs & Schieffelin, 1989).…”
