OK, since I'm the one who inadvertently introduced you to this terminology, I guess I should be the one to explain it. First of all, let me just say that the terms "unaccusative" and "unergative" are entirely misleading and unintuitive; I use them only because they have become standard in the linguistics literature. The distinction between unaccusative and unergative verbs is structural. The idea is this: Transitive verbs have two structural positions or relations, which we could call the "subject" position/relation and the "object" position/relation. Unergative verbs are intransitives in which the single argument has the basic properties of a subject. In cases where unergative verbs alternate with transitives, the subject of the unergative corresponds to the subject of the transitive: Transitive: John ate the sushi. Unergative: John ate. Unaccusative verbs are intransitives in which the single argument has some of the properties usually associated with the object position/relation. In cases where unaccusative verbs alternate with transitives, the subject of the unaccusative corresponds to the object of the transitive: Transitive: John sank the ship. Unaccusative: The ship sank. Notice in this second pair that the noun phrase "the ship" bears the exact same semantic relationship to the verb "sink" in both sentences. Yet in the first sentence it is the object of the verb, while in the second sentence it is the subject of the verb. How do we explain this? In order to maintain a consistent relationship between semantic functions and grammatical positions/relations, we could assume that in the sentence "The ship sank", "the ship" starts out as the direct object of the verb "sink" (as in the transitive sentence) and is then transformed into a subject by some operation (in Chomsky's Government-Binding theory, this operation would be movement). Does that explain the difference adequately? If not, I'll try again... Matt.
