Differential Object Marking: Iconicity vs. Economy. Natural Language & Linguistic Theory 21(3): 435–483.

Formalizes the core OT analysis: Harmonic Alignment of prominence scales with the relational scale (Subj > Obj) derives two constraint families:

Rankings are fixed within each family but free between families. The factorial typology over all consistent interleavings predicts exactly the attested DOM patterns.

For the 3-element animacy scale {Hu > An > In}, 4 of 8 logically possible patterns are generated — exactly the monotone ones (Table 17, p. 476).

Connection to Existing Infrastructure #

The predicted DOM profiles are matched against the DOMProfile language data in Phenomena.Case.Typology, verifying that every attested pattern corresponds to a possible OT grammar.

@[irreducible]

All interleavings of two lists, preserving internal order of each.

Given two constraint families with fixed internal rankings, this generates all total orders consistent with both. The number of interleavings of lists of lengths m and n is C(m+n, m).

                          The 3-element animacy scale yields exactly 4 language types, not 8 (Table 17, p. 476).

                          Every generated type is monotone: if An is marked then Hu is too; if In is marked then An is too (Aissen's central prediction).

                          Type 1: mark all (Hu + An + In). Extreme iconicity.

                          Type 2: mark Hu + An only. Russian pattern (animate accusative).

                          Type 3: mark Hu only. Spanish pattern (personal a).

                          Type 4: mark none. No DOM (economy dominates).

                          Mark In without An: never generated.

                            The 2-element definiteness scale {Pro > D} from §4 of the paper, where "D" covers definite NPs (including proper names). This gives the same 3-type factorial typology as any 2-element scale.

                            Convert a Scale2Cand to a definiteness-based DOMProfile. High = personalPronoun, Low = properName + definite (i.e., ≥ definite).

                              The number of consistent rankings grows as C(2n, n). For n=2: C(4,2) = 6. For n=3: C(6,3) = 20.

                              An NP enriched with referential prominence properties.

                              Structural case assignment (dependent case) is blind to these properties — it cares only about c-command and lexical case. DOM then consults prominence to decide overt realization.

                                              Two conditions:

                                              1. The dependent case algorithm assigns ACC (syntax).
                                              2. The DOM profile marks this prominence cell (morphology).

                                                A standard transitive clause with a fixed subject (human pronoun) and a variable-prominence object. Both lack lexical case.

                                                  In accusative transitives, the object receives abstract ACC regardless of its animacy or definiteness. Dependent case is prominence-blind.

                                                  The overt marking profile produced by running the full pipeline (dependent case + DOM filter).
