Progressive constructions in Germanic are usually studied as progressive constructions—that is, exclusively so. I characterize this as a top-down approach to aspect, which, I argue, harbors the risk of overlooking relevant language-specific structures that are similar in form and meaning. This paper, therefore, advocates taking a bottom-up approach. Based on a case study of the prepositional progressive in Dutch (aan het-progressive), I claim that this approach is of added empirical and theoretical value. Drawing on construction-based theories, the relevant patterns—dubbed situational constructions—are analyzed in terms of horizontal constructional links.*

自上而下与自下而上的体体方法：荷兰介词进行时的案例

日耳曼语中的进行式结构通常被作为进行式结构来研究——也就是说，完全如此。我将其描述为一种自上而下的方面方法，我认为，这种方法存在忽视形式和含义相似的相关语言特定结构的风险。因此，本文主张采取自下而上的方法。基于荷兰语介词进行体的案例研究（阿安赫特-渐进），我认为这种方法具有附加的经验和理论价值。借鉴基于建构的理论，相关模式被称为情境建构——根据水平结构联系进行分析。*
