The concept of causality is among the primary human concept- ualizations and thus carries special significance in its linguistic represen- tation. This is well illustrated by numerous cognitive explorations with respect to ``force dynamics``. Since the human construal of caused events in real-world situations involves diversified classification of the causal force, the causal force takes on equally diverse linguistic representations. In Korean such dimensionality of causality is perceptually attributable to, and analytically retrievable from, the semantics of the source lexemes of the complex postpositions and connectives, where the so-called defective nouns participate as a nominal component of the formal constructs. The typology of causality along the physical dimension bears significance in that the members of each subcategory exhibit different behavior in terms of their syntagmatic cooccurrence, as a result of differing semantic constraints. This paper shows that there is a systematic correlation between the semantics of the source nominals and that of the grammaticalized forms; that the dimensional differences can account for the interchangeability and incom- patibility among complex postpositions and connectives; and that the grammaticalization process often involves subjectification of the language user, whereby only a particular aspect of an event is selected for emphasis.

Seongha Rhee. 2001. Grammaticalization of Verbs of Cognition and Perception. Studies in Modern Grammar 24, 111-135. This paper is an exploration of the grammaticalization phenomena displayed by the verbs of cognition and perception. Drawing upon cross-linguistically attested data, this paper shows that verbs of cognition and perception predominantly grammaticalize into epistemic markers. This is a natural consequence because the grammaticalized markers exhibit semantic residue of the source items, which, in this case, make direct reference to the sources of the human construal of the world affairs. This paper explicates how other grammatical functions are developed from these verbs. In so doing it also argues that the features that are selected for grammaticalization are those that are experientially salient features in conceptual event schemas.
