The concept of causality is among the primary human conceptualizations, and thus carries special significance in its linguistic representation. This is well illustrated by numerous cognitive explorations advanced by Talmy (1988, 1995) and Sweetser (1990) with respect to 'force dynamics' and by Bybee (1985) with respect to relevance in the ordering patterns of verbal morphology. Since the human construal of caused events in real-world situations involves diversified classification of the causal force, it is not surprising that the causal force takes on equally diverse linguistic representations.
Korean is an interesting language where such dimensionality of causality is perceptually attributable to, and analytically retrievable from, the semantics of the source lexemes of the complex postpositions, where the so-called defective nouns participate as a nominal component of the formal construct. There has been continued interest in the studies of defective nouns (Ahn 2001, Rhee 2007a for an overview), mostly with respect to their morphosyntactic and categorial characteristics. However, the causal connectives in the form of complex postpositions have received less attention from the grammaticalization perspective (cf. Ahn 1997 is a major exception). Furthermore, it has not been noted yet that the defective nouns in these causal connectives have the dimensionality variable as part of their inherent semantics, and that this dimensionality determines the behavior of the complex postposition. This paper intends to fill the gap.
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. For instance, the complex postpositions with Dimension 0 nominals tend to signify direct, yet often incidental, dynamic contacts between the causer and the caused, whereas those with Dimension 1 nominals signify linear, often temporal, connection of the causation event. In the same fashion, complex postpositions with Dimension 2 nominals largely signify causal forces operating as the background or basis, and those with Dimension 3 tend to signify more overpowering causal force, i.e., the recipient is subject to multi-dimensional causal force as if it is located 'within' a gust of wind or a cylindrical container. As for Dimension 4, the linguistic representation also shows the human's real-world perceptual situation, i.e. the fourth dimension is not as prominent and is often perceived and represented reductively as the third dimension. Consequently, the nominals in Dimensions 3 and 4 tend to be interchangeable.
Of numerous implications in the studies of language and cognition, certain observations seem to merit special attentions: that there is a systematic correlation between the semantics of the source nominals and that of the grammaticalized forms (cf. 'persistence' Hopper 1991; 'the source determination hypothesis' Bybee et al. 1994); that the dimensional differences can account for the interchangeability and incompatibility among complex postpositions; that there is a strong tendency to recruit particular lexemes for the purpose of causality representation, illustrating how human cognition is reflected in grammar (Heine 1997); and that the grammaticalization process often involves subjectification of the language user (Traugott 1982, Traugott & König 1991), whereby only a particular aspect of event is selected for emphasis (Rhee 2007b). This paper illustrates the grammaticalization processes of the individual complex postpositions and discusses how dimensional differences influence the emergence of grammatical functions.
