Italian Adjective Agreement

[AZ25d]

Italian adjectives are inflected for gender and number (φ-features) in both predicative and attributive use, but NOT for case (κ-features). The agreement forms are identical across positions (36).

Under the MAG, Italian fails condition (a) because φ/κ-completeness requires case marking: agreementPhiKappaComplete = false. Since the Attr head is null and affixal (carrying κ-features), the ICP forces adjacency. Italian prenominal adjectives therefore obey the HFF. The analysis is given in (72).

def Italian.AdjAgreement.phiFeatures : List Agreement.AgrFeature

Italian adjective φ-features: number and gender only.

Equations

• Italian.AdjAgreement.phiFeatures = [Agreement.AgrFeature.number Number.plural, Agreement.AgrFeature.number Number.singular, Agreement.AgrFeature.gender 0, Agreement.AgrFeature.gender 1]

def Italian.AdjAgreement.dpFeatures : List Agreement.AgrFeature

Italian DP features include κ (case is always a DP feature per fn 17, even when not morphologically realized on adjectives).

Equations

• Italian.AdjAgreement.dpFeatures = Italian.AdjAgreement.phiFeatures ++ [Agreement.AgrFeature.kappa Case.nom, Agreement.AgrFeature.kappa Case.acc]

def Italian.AdjAgreement.entry : Agreement.AdjAgreementEntry

Equations

• Italian.AdjAgreement.entry = { predFeatures := Italian.AdjAgreement.phiFeatures, attrFeatures := Italian.AdjAgreement.phiFeatures, dpFeatures := Italian.AdjAgreement.dpFeatures }

theorem Italian.AdjAgreement.same_agreement : entry.sameAgreement = true

Italian pred = attr (both carry φ).

theorem Italian.AdjAgreement.not_phi_kappa_complete : entry.phiKappaComplete = false

Italian is NOT φ/κ-complete: adjectives lack case.
