Explanation
Nominative–accusative alignment groups the sole core argument of an intransitive predicate (S) with the more agent-like argument of a transitive predicate (A), distinguishing them from its more patient-like argument (P). The pattern must be specified for a domain: case, verbal person marking or syntactic behaviour. A case pattern does not automatically establish the same alignment in every domain. Pronouns and full noun phrases can also differ. What matters is the distribution of forms and functions, not an assumption that every subject acts intentionally.
Movement of thought
1. Compare intransitive and transitive constructions. 2. Identify S, A and P. 3. Specify the domain of marking. 4. Check splits by form type and construction.
Scientific use case
A language description could construct separate S/A/P paradigms for pronouns and full noun phrases.
Example
Constructed using the English pronominal pattern: We arrived; we saw them; they saw us. We marks S and A, whereas us marks P.
Counterexample
English you has no corresponding form contrast here. One pronoun cannot determine the classification of the entire case system.
Distinction
Accusative alignment, accusative case and active voice belong to different descriptive levels.
Effect on thought and perception
The comparison reveals which participants receive the same grammatical treatment.
Resonance
Different events share a form when their participants occupy the same grammatical place.
