Gender Features and Coordination Resolution in Greek and Other Three-Gendered Languages: Implications for the Crosslinguistic Representation of Gender. Linguistic Inquiry (Early Access).

Core result #

Cross-linguistic variation in coordination resolution (Table 2) is derived from three interacting components, without stipulated defaults:

  1. Feature geometry: language-specific hierarchies of privative gender features. In Greek, FEM is a dependent of MASC (= animate), so a feminine nominal also bears MASC. In Icelandic, MASC (= male) and FEM are independent under CLASS — neither entails the other.

  2. Dual-feature system: interpretable features (iFs → LF) vs uninterpretable features (uFs → PF), linked by a redundancy rule that copies iFs to empty uF slots at Transfer.

  3. Percolation + conversion: universal coordination resolution. iFs percolate from conjuncts to &P; shared iFs survive intersection (conversion); the Subset Principle selects the inflectional exponent.

Resolution uses GenderResolution.resolve — the single compositional endpoint — instantiated with GenderNode as the feature type. Each prediction is a verified theorem.

Privative feature nodes in the gender geometry (§2.2).

@cite{adamson-anagnostopoulou-2025} modifies @cite{harley-ritter-2002}: features are organized in language-specific hierarchies where more specific features entail broader features. The same labels appear across languages, but their geometric arrangement — and hence their semantic content — varies.

Language-specific geometries:

  • Greek (17): CLASS > MASC > FEM (linear chain)
  • Icelandic (63): CLASS > {MASC, FEM} (independent siblings)
  • BCS (74): CLASS > INDIV > {GRP, MASC > ANIM > FEM}

                  Greek feature geometry (17) #

                  CLASS > MASC > FEM (linear chain).
                  Feature interpretations (18):
                  - CLASS: λx. x is an entity
                  - MASC: λx. x is animate
                  - FEM: λx. x is a woman
                  
                  Having FEM entails MASC; having MASC entails CLASS.
                  Lexical Complementarity (19) restricts: iMASC picks out ⟦MASC⟧ − ⟦FEM⟧
                  (animate non-women); iFEM picks out women; iCLASS picks out entities. 
                  

                  (22a) Mismatched humans → {CLASS, MASC} → masculine plural. Intersection: {CLASS,MASC,FEM} ∩ {CLASS,MASC} = {CLASS,MASC}. FEM is eliminated because only one conjunct bears it.

                  (22b, 40a-c) All inanimate mismatch combinations → {CLASS} → neuter. Percolation extracts only iCLASS from each conjunct (uFs excluded). This is NOT default insertion — it is the result of intersecting the iF sets, which contain only iCLASS for all inanimates.

                  Mismatch Resolution Hypothesis (24): no default feature insertion. All resolution outcomes have non-empty intersection (matching).

                  Fixed-gender human nominals (§3.2) #

                  *megalofiia* 'genius' is **grammatically** feminine (uFs) but its
                  **conceptual** gender (iFs) tracks the referent. Resolution operates
                  on iFs — crucial evidence for the Mismatch Resolution Hypothesis.
                  
                  *thima* 'victim' is grammatically neuter (uF = {CLASS}) but
                  conceptually masculine/feminine depending on referent. 
                  

                  (36) megalofiia (male referent) + sister → masculine (M♂ + F♀ = M). Despite both being grammatically feminine, iF resolution yields {CLASS,MASC} ∩ {CLASS,MASC,FEM} = {CLASS,MASC} → MASC.

                  (37) thima (female referent) + her mother → feminine (N♀ + F♀ = F). Neuter noun's iFs are feminine (referent is female): {CLASS,MASC,FEM} ∩ {CLASS,MASC,FEM} = {CLASS,MASC,FEM} → FEM.

                  When a human (percolating iFs) and an inanimate (percolating uFs)
                  are coordinated, PF realization succeeds only if the features map
                  to the same inflection class. Otherwise: PF crash → ineffability.
                  
                  Y-model significance: the crash happens at **PF**, not in narrow
                  syntax. [H + I] coordination is syntactically well-formed; the
                  problem is exponence of the resolved features.

                    Fixed-gender humans + inanimates (§3.5) #

                    The paper's strongest evidence for the iF-based analysis. When a
                    **fixed-gender human** is coordinated with an inanimate, the PF
                    convergence depends on the human's **iFs** (conceptual gender),
                    not their **uFs** (grammatical gender).

                    (57a corollary) thima (N♀, male ref) + fotografia (F■) → PF crash. iFs of victim (male) = {CLASS, MASC} → VI → MASC. uFs of picture = {CLASS, MASC, FEM} → VI → FEM. MASC ≠ FEM → crash.

                    Uniform inanimate coordination (38a-c) #

                    When two inanimates share the same grammatical gender, resolved
                    agreement matches that gender. Under the paper's analysis, this
                    obtains when inanimates percolate **uFs** (the alternative
                    derivation in (39)): the &P has a singleton uF set, and PF
                    realization succeeds with the shared exponent. 
                    

                    (38a) F■ + F■ = F: fusta 'skirt' + bluza 'T-shirt'.

                    (38b) M■ + M■ = M: anaptiras 'lighter' + fakos 'torch'.

                    (38c) N■ + N■ = N: piruni 'fork' + kutali 'spoon'.

                    (2a, 58) Clausal subjects lack gender features entirely. No features to percolate → no vocabulary item matches → neuter (the elsewhere exponent, least specified).

                    Icelandic feature geometry (63) #

                    ```
                    (i/u)CLASS
                       / \
                    MASC   FEM    ← independent (no entailment)
                    ```
                    
                    Unlike Greek, FEM is NOT a dependent of MASC. The crucial difference:
                    MASC means 'male' (not 'animate'), so gender-mixed groups are excluded
                    from both MASC (not all male) and FEM (not all female).
                    Lexical Complementarity: no restriction between MASC and FEM
                    (neither is a subset of the other). 
                    

                    (60) Mismatched humans → {CLASS} → neuter. {CLASS,MASC} ∩ {CLASS,FEM} = {CLASS}. Because MASC and FEM are independent siblings, only CLASS survives intersection.

                    (59) Mismatched inanimates → {CLASS} → neuter. frægð 'fame' (F) + frami 'success' (M) → neuter plural. All Icelandic inanimates share iFs = {iCLASS} regardless of grammatical gender — uFs (uFEM, uMASC) are excluded from resolution.

                    The geometry contrast: same labels, different geometry, different outcome. Greek {CLASS,MASC,FEM} ∩ {CLASS,MASC} = some {CLASS,MASC}. Icelandic {CLASS,FEM} ∩ {CLASS,MASC} = some {CLASS}. Same mechanism, different input → different result.

                    Key differences from Greek and Icelandic:
                    1. MASC is under INDIV (not directly under CLASS)
                    2. Neuter ≈ mass (no INDIV) → can't be counted or coordinated as count
                    3. All coordinatable nominals have INDIV → resolved features include
                       at least {INDIV} → vocabulary maps to masculine
                    
                    Vocabulary consequence: masculine is the "default" for coordination
                    not by stipulation but because INDIV (required for plural) maps to
                    masculine via the Subset Principle. 
                    

                    (68) Mismatched humans → {CLASS, INDIV, MASC, ANIM} → masculine. {CLASS,INDIV,MASC,ANIM,FEM} ∩ {CLASS,INDIV,MASC,ANIM} = {CLASS,INDIV,MASC,ANIM}.

                    Mismatched M + F inanimates → {CLASS, INDIV, MASC} → masculine. Both conjuncts share {CLASS, INDIV, MASC} as iFs; ANIM + FEM on the feminine noun are uFs, excluded from resolution.

                    (69) Mismatched N + F inanimates → masculine. znanje 'knowledge' (N) + intuicija 'intuition' (F). Neuter is mass (iFs = {CLASS}); feminine inanimate has iFs = {CLASS, INDIV, MASC}. Intersection = {CLASS}. But coordination introduces GRP (entailing INDIV), so the &P bears {CLASS, INDIV} at minimum → Subset Principle yields masculine.

                    NB: The formalization models this by checking that the gender resolution itself yields {CLASS}, and the coordinate structure's INDIV (from GRP/plural) independently ensures masculine VI.

                    After coordination introduces INDIV, the combined features ({CLASS} from resolution + {INDIV} from GRP) map to masculine.

                    (70) Even matched neuters → masculine when coordinated. selo 'village' (N) + brdo 'hill' (N). Individual neuter DPs are mass (iFs = {CLASS}). Resolution: {CLASS} ∩ {CLASS} = {CLASS}. But coordination introduces GRP (entailing INDIV). The combined {CLASS, INDIV} at &P maps to masculine via VI — INDIV is present → masculine.

                    Redundancy rule (13): copy iF values to empty uF slots at Transfer. If uFs are already filled (arbitrary gender), the rule does not apply.

                    Y-model: this operation occurs at Transfer, the boundary between narrow syntax and the PF/LF interfaces.

                      The implicational feature hierarchy (CLASS > MASC > FEM) predicts the absence of ABA syncretism patterns (fn. 19). Neuter and feminine can never be syncretic to the exclusion of masculine — since the masculine feature set {MASC} is a proper subset of feminine {FEM,MASC} and a proper superset of neuter ∅, any syncretism of N and F would also include M.

                      Greek inflection: M is always "between" N and F in feature specificity. This rules out N = F ≠ M syncretism patterns.

                      Geometry → outcome #

                      The paper's central thesis: cross-linguistic variation in resolution
                      follows from differences in feature geometry, not from different
                      resolution mechanisms or stipulated defaults. Same labels, same
                      mechanism, different geometry → different outcome.
                      
                      We formalize each language's geometry as a function from a base
                      gender node to the full set of entailed iFs, then prove that
                      resolution outcomes follow from geometry alone. 
                      

                      Greek geometry (17): CLASS > MASC > FEM (linear chain). FEM entails MASC entails CLASS.

                        Instances For

                          The linear chain geometry guarantees that mismatched human resolution retains MASC — because both conjuncts bear iMASC (FEM entails MASC).

                          The independent geometry means human mismatch loses both MASC and FEM — only CLASS survives intersection.

                          The geometry functions reconstruct the noun data: Greek nouns are exactly the geometry applied to their most specific iF.

                          Entailment asymmetry: in the linear chain (Greek), FEM's iFs are a superset of MASC's iFs. In the independent geometry (Icelandic), neither is a superset of the other. This is WHY the intersection outcomes differ.

                          procedurally. Here we define the same vocabulary as `FeatureVI` items
                          (@cite{halle-marantz-1993}) and prove that `subsetPrinciple` selects
                          the same exponents. This connects the gender resolution mechanism to
                          the formal DM vocabulary insertion framework.

                              Same vocabulary + different geometry → different outcome. Greek and Icelandic share the vocabulary (both use greekVocabItems), but the Subset Principle yields different results because the geometry produces different intersections.

                              The `FeatureOrder` structure packages a feature geometry — its nodes
                              and the bundle function that maps each node to its full set of
                              entailed features. This formalizes the paper's central insight that
                              cross-linguistic variation is geometry variation.

                                  non-empty intersections — no default insertion is ever needed.
                                  
                                  We verify this via the `satisfiesMRH` predicate from
                                  `GenderResolution`, instantiated with the geometry-derived bundles. 
                                  

                                  Greek satisfies MRH: all pairwise resolutions succeed.

                                  Icelandic satisfies MRH: all pairwise resolutions succeed. Despite different outcomes (neuter for humans instead of masculine), no resolution yields an empty intersection.

                                  Both satisfy MRH — this is the paper's "no default insertion" claim: the difference between Greek and Icelandic is the content of the intersection, not whether it exists.

                                  Three or more conjuncts #

                                  `resolveN` extends binary resolution to n-ary coordination via
                                  iterated intersection. The predictions are the same: gender-matching
                                  agreement emerges iff all conjuncts share a feature (after percolation). 
                                  

                                  Greek: three mismatched humans → {CLASS,MASC} (FEM eliminated). FEM + MASC + FEM: FEM present in first and third but not second.

                                  Icelandic: three mismatched humans → {CLASS} → neuter. Because MASC and FEM are independent, any mismatch loses both.
