This paper demonstrates that the progressive interpretation in Ga is an effect of the interaction between the imperfective aspect and a definite description of events. Crucially, the data from Ga point to the consequences of the view that definite descriptions of events encode the familiarity of the discourse referent and its uniqueness in bearing the property in question. Namely, they yield direct evidentiality and the necessary ongoingness of the event at the topic time. Thus, the paper identifies previously unattested variation in the semantics of the progressive in a cross-linguistic perspective and shows that not only lexical but also grammatical aspect exhibits striking parallelisms with the nominal domain.

事件的明确描述：Ga（Kwa）的渐进解释

本文论证了 Ga 中的渐进式解释是不完美方面与对事件的明确描述之间相互作用的结果。至关重要的是，来自 Ga 的数据指出了以下观点的后果，即事件的明确描述编码了话语所指对象的熟悉程度及其在承载相关属性方面的独特性。也就是说，它们在主题时间产生直接证据和事件的必要持续性。因此，本文从跨语言的角度确定了先前未经证实的渐进式语义的变化，并表明不仅词汇方面而且语法方面都与名义域表现出惊人的相似性。
