@cite{aissen-2003}: Differential Object Marking @cite{aissen-2003} #
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:
- Iconicity (*Ø/X): penalizes zero-marked objects at prominence level X. Fixed ranking: *Ø most prominent >>... >> *Ø least prominent.
- Economy (*!/X): penalizes marked objects at prominence level X. Fixed ranking: *!/least prominent >>... >> *!/most prominent.
Rankings are fixed within each family but free between families. The factorial typology over all consistent interleavings predicts exactly the attested DOM patterns.
Key Results #
| Scale Size | Consistent Rankings | Language Types | Impossible Patterns |
|---|---|---|---|
| 2 elements | 6 | 3 | Mark low without high |
| 3 elements | 20 | 4 | Any non-monotone pattern |
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.
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).

Every OT-generated animacy type produces a monotone DOMProfile.
Spanish DOM (human only) matches OT Type 3 (Hu only).
Russian DOM (animate+) matches OT Type 2 (Hu + An).
No-DOM profile matches OT Type 4 (none marked).
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).

Catalan DOM (pronouns only) matches 2-element Type 2 (High only).
Turkish DOM (definite+) matches 2-element Type 1 (both marked).
Hebrew DOM (definite+) also matches 2-element Type 1.
Of 4 logically possible 2-element patterns, OT generates exactly 3.
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.

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

Instances For
Every OT-predicted animacy type, run through the full pipeline, produces a monotone overt marking profile.
The pipeline preserves monotonicity for all attested DOM languages.
All 8 attested DOM profiles, run through the accusative case pipeline, produce overt marking that is faithful to the DOM input AND monotone.
