"Grammatical Relation Changing Constructions in Korean: A Functional-Typological Study" Jaehoon Yeon (SOAS) This is a functional-typological study of Case-marking, Grammatical Relations and Semantic Roles. We analyse Korean data in the light of typological universals, to show how cross-linguistic generalizations contribute to understanding structures of individual languages. In particular, we discuss constructions that change the grammatical relations of noun phrases by moving them up or down the grammatical hierarchy. These 'Grammatical Relation changing constructions' comprise causative, passive, anticausative, space-object, experiential, and possessor-ascension constructions. Special emphasis is given to double-nominative and double- accusative constructions, in which the normal correspondence between morphological case, grammatical relation and semantic role breaks down. Ch.1 is an introduction to our methodology and sets out the normal mapping relations between grammatical relations and semantic roles. Ch.2 analyses the so-called double-subject constructions; it is argued that this notion results from a confusion of morphological case and grammatical relation and that only one of the two nominative-marked noun phrases should be assigned subject status. Ch.3 discusses the syntax and semantics of causee and argues that the degree of control exercised by the causee is reflected in its case- marking. Ch.4 deals with passive constructions in terms of prototype approach; the semantic differences between the morphological and the analytic passive are explained in terms of spontaneity and intention. Animacy, control and affectedness play important roles in explaining constraints on subject assignment and the choice of voice. It is also shown that object-retained passive constructions in Korean result from 'double- accusative' constructions. Ch 5 deals with the overlap of causative and passive which arises ub=nder specific conditions, especially when the direct object of the base verb is a possession or body-part of the causative subject. Ch.6 is devoted to the neutral-verb constructions and compares their semantic struycture to the causative and the passive. Ch.7 deals with other types of grammatical relation changing constructions and claims that the difference in case-marking can be explained by reference to the degree of transitivity. The marking for the object of high transitivity is the accusative and the marking for the object of low transitivity is non- accusative.
