Italian Noun Lexicon Fragment

Italian NP structure with gender. Bare arguments restricted (@cite{chierchia-1998} [-arg, +pred]). Italian is the star witness for Chierchia's predOnly parameter: nouns denote predicates and require a determiner to be argumental.

Determiner System

@cite{chierchia-1998}

Italian has a richer article paradigm than French, with allomorphy conditioned by gender, number, and phonological context:

• Definite: il/lo/la (sg), i/gli/le (pl)
• Indefinite: un/uno/una (sg only)
• Partitive: del/dello/della (sg mass), dei/degli/delle (pl)

The partitive articles (di + definite article) serve as the obligatory indefinite plural — Italian has no bare plural arguments.

theorem Fragments.Italian.Nouns.definitePluralDenotesKind : Semantics.Kinds.NMP.CanDenoteKind italianMapping True

Italian definite plurals denote kinds: derived from predOnly + overt D. Because Italian is [-arg, +pred], D is required for argumenthood. With D present, the noun maps to a kind via ∩.

theorem Fragments.Italian.Nouns.barePluralCannotDenoteKind : ¬Semantics.Kinds.NMP.CanDenoteKind italianMapping False

Italian bare plurals cannot denote kinds: derived from predOnly + no D. Without D, Italian nouns remain predicates. No covert ∩ is available.

theorem Fragments.Italian.Nouns.barePluralDenotesProperty : Semantics.Kinds.NMP.CanDenoteProperty italianMapping

Italian bare plurals denote properties: derived from predOnly. All [+pred] languages allow property denotation for nouns.
