de Swart and Sag (2002): Negation and Negative Concord in Romance #

De Swart and Sag take the French n-words personne, rien and aucun N to be negative quantifiers and derive the two readings of a clause with two of them from two ways of composing quantifiers. Iteration, ordinary function application, puts one in the scope of the other and gives the double negation reading; resumption absorbs both into one quantifier over pairs and gives the concord reading. Only anti-additive quantifiers resume, which no is and few is not. Sentential negation is anti-additive too, a quantifier of type 0 that binds no variable, so it can join a resumption and is then semantically empty; standard French keeps pas out of resumption, so pas with an n-word reads only as a double negation.

Retrieval composes two n-words by iteration, function application, or by resumption into a single quantifier over pairs ((29)).

      def DeSwartSag2002.reading {α : Type u} [Fintype α] :
      Mode → (α → Prop) → (α → Prop) → (α → α → Prop) → Prop

      The reading of a clause whose two arguments are n-words with restrictors A and B and whose verb denotes R, as Personne n'aime personne ((13), (14)).

        theorem DeSwartSag2002.reading_iteration_iff {α : Type u} [Fintype α] {A B : α → Prop} {R : α → α → Prop} :

        The double negation reading, ¬∃x¬∃y R(x, y) ((13)), is every·some, as the gloss of (33b) has it: everyone loves the son of someone.

        theorem DeSwartSag2002.reading_resumption_iff {α : Type u} [Fintype α] {A B : α → Prop} {R : α → α → Prop} :

        The concord reading, ¬∃x∃y R(x, y) ((14)), is no·some ((17)).

        theorem DeSwartSag2002.reading_resumption_and_not_iteration :
        (reading Mode.resumption (fun (x : Fin 1) => True) (fun (x : Fin 1) => True) fun (x x_1 : Fin 1) => False) ∧ ¬reading Mode.iteration (fun (x : Fin 1) => True) (fun (x : Fin 1) => True) fun (x x_1 : Fin 1) => False

        The two readings differ: of one individual who loves no one, Personne n'aime personne is true on its concord reading and false on its double negation reading.

        Anti-additivity #

        Concord is restricted to anti-additive quantifiers such as personne 'no one', to the exclusion of the merely downward-entailing peu 'few'. Negation is anti-additive as well (NaturalLogic.isAntiAdditive_compl).

        No is anti-additive in its scope: none of A is in S ∪ S' iff none is in S and none in S'.

        Few is downward-entailing (Quantifier.GQ.scopeAntitone_few) but not anti-additive: of three individuals, few are 0 and few are 1, but not few are 0 or 1.

        Some is not anti-additive: of one individual, some is in ⊤ ∪ ⊥ but none is in ⊥.

        Of the readings of aucun, the one that is anti-additive on every finite domain, as a concord item must be, is the negative quantifier.

        Negation as a quantifier of type 0 #

        A negator binds no variable, so when it joins the resumption of n-words it leaves the resumptive quantifier unchanged: in concord, negation is semantically empty (§6.1). The same holds of sans 'without' (§6.2).

        def DeSwartSag2002.negReading {α : Type u} :
        Mode → (α → Prop) → (α → Prop) → Prop

        The reading of a negator with one n-word: negation iterated over the n-word, or absorbed into its resumption.

        Equations
        Instances For

          Negation iterated over an n-word gives the existential, the only reading of standard French Il ne va pas nulle part 'he goes somewhere' ((36a)), since constraint (40) keeps pas out of resumption.

          Absorbed into the n-word's resumption, the negator adds nothing, as sans in Anne est partie sans rien dire 'Anne left without saying anything' ((56)).
