Oblique Extraction Data

@cite{elkins-torrence-brown-2026}

Theory-neutral empirical data on oblique extraction morphology in SJO Mam.

The primary data is in Fragments.Mayan.Mam.ExtractionMorphology, which defines data points, judgments, and generalizations. Bridge files connecting this data to specific theories are in Phenomena/FillerGap/Bridge/:

• MinimalismOblExtraction.lean: Agree + Spellout analysis
• MayanExtractionComparison.lean: Mam =(y)a' vs. K'iche' wi

Key Empirical Findings

1. =(y)a' is oblique-specific: Subject (AF) and object extraction do not trigger it (§3).
2. =(y)a' is clause-size-sensitive: Licensed iff Voice is projected (§6).
3. Multiple spellout: In long-distance extraction, =(y)a' can appear on both matrix and embedded predicates (Table 4, §6.2).
4. Island-sensitive: =(y)a' is blocked by islands, arguing against a resumptive analysis (§7.1).
5. Not Agent Focus: Co-occurs with passive -njtz (§7.2).
6. Temporal obliques exempt: 'when' does not trigger =(y)a' (§8.1).
