Did you perchance mean accusative?
- un- + accusative, from the fact that in a nominative-accusative language, the accusative case, which marks the direct object of a transitive verb, typically marks the non-volitional role. In unaccusative verbs, the non-volitional arguments do not take the accusative case. (Wiktionary)
“And, once again looking over my shoulder at some teaching preparation, What's an unaccusative?”
