This paper presents a corpus-based analysis of the semantics of the German am V-inf sein construction, or am-progressive. Like its English counterpart and many other progressive constructions in the world's languages, the am-progressive is shown to convey not only a variety of aspecto-temporal meanings, but also a range of (inter)subjective qualifications, such as intensification, irritation, and evasiveness. These (inter)subjective connotations are argued to reflect the am-progressive's core meaning of epistemic contingency, which we believe is instantiated in all of its uses.*

This paper investigates the possibility of subject omission in the history of Icelandic, including the syntactic and pragmatic conditions under which it could arise. Based on regression analysis of substantial data drawn from the IcePaHC corpus, we provide robust quantitative support for Hjartardóttir's (1987) claim that null subjects persist until a very late stage in Icelandic. We also argue, contra Sigurðsson (1993), that only one licensing mechanism is needed for null subjects in early Icelandic. Moreover, on the basis of the position of the null subjects and their person features, we argue that the modern stage, where (predominantly 3rd person) pro-drop yields to a system permitting topic drop of all persons, arises in Icelandic in the early twentieth century.*
