Approaches to the semantics of numerals

Symmetric approaches Asymmetric approaches
Ambiguity: Numerals are lexically ambiguous
between two construals (Horn, 1992)
Lower-bounded basic: The upper-bounded construal is derived (Horn, 1984; Levinson, 2000; Chierchia et al., 2008)
Underspecification: Numerals are under-specified; interpretation is driven by
relevance (Sperber & Wilson, 1985/1995; Carston, 198)
Upper-bounded basic: the lower-bounded
construal is derived (Breheny, 2008)
