Explanation
Ergativity is a grammatical alignment pattern in which the sole core argument of an intransitive verb is grouped with the patient-like argument of a transitive verb, while the agent-like transitive argument is treated differently. In case systems, the first two commonly appear in the absolutive and the transitive agent in the ergative. This organisation challenges the assumption, familiar from nominative–accusative languages, that “subjects” form the same natural class everywhere. Ergativity may involve case, agreement, syntax, or only particular persons, tenses, aspects, and constructions; many languages show split systems. The concept therefore opens not an exotic reversal but a comparative perspective on how languages group event participants and which analytical categories are actually supported within each language.
Movement of thought
1. Three roles are first compared: the single argument of an intransitive verb and the agent and patient of a transitive verb. 2. An ergative pattern groups the intransitive argument with the transitive patient and treats the transitive agent separately. 3. Case, agreement, or syntactic behaviour makes this alignment visible, though not necessarily throughout every domain of a language. 4. A counter-test controls split conditions, valency, and concrete diagnostics and avoids importing European subject categories without examination. 5. The event returns as a language-specific order of participants in which acting and undergoing may be coupled differently.
Scientific use case
Linguistic typology and syntax compare case, agreement, coordination, and reference accessibility. Corpus and fieldwork document splits by person, aspect, or clause type rather than labelling an entire language uniformly.
Example
In a language with ergative case, “the child” in “the child fell” and “the ball” in “the child threw the ball” bear the same absolutive form, while only the thrower is ergative.
Counterexample
English I in “I sleep” and “I see him” has the same subject form, while the object is marked differently. This is a nominative–accusative pattern rather than an ergative–absolutive one.
Distinction
Distinguish ergativity from passive constructions, semantic agentivity, and a total “reversal” of subject and object. It is an alignment pattern with possible splits; morphological and syntactic ergativity require separate diagnostics.
Effect on thought and perception
Ergativity relativises familiar subject–object orders and reveals that grammatical systems group event participants along different axes.
Resonance
Languages draw different connecting lines among participants in an event; the same scene thereby receives a different grammatical distribution of prominence.

Historical background
Comrie’s typological treatment distinguishes S, the sole argument of an intransitive verb, from A and P in a transitive construction. Ergative alignment treats S together with P rather than A. This comparative framework documents the concept beyond a particular case ending, but the chapter does not establish the earliest English or German technical use.
How conceptual history changes the analysis
Ergativity is an alignment pattern of arguments, of which overt case marking is one realization.
