A Diachronic Study on Argument Structure of the Korean Transitive Verbs of the 15th century(2): The Focus is the Formation of ‘NP-lo’ Arguments

The study of structure has been mainly focused on the contemporary Korean. The earlier structures have been studied only a little. In addition, there is no diachronic study of structure change based on all the verbs. From the motivation, all the Korean transitive verbs of 15th century were made an object of this work in order to investigate the historical aspect of the structure change. In particular, we have systematically investigated the extended structure of transitive verb by the formation of ‘NP-lo’ argument. To obtain the objective validity, most computerized material of Hangul in archaic words were made an objective of the primary analysis. In the structure of transitive verbs, the ‘NP-lo’ arguments can be formed by the following two cases. First, the ‘NP-lo’ argument can be formed in the structure, ‘NP-i NP-lul V’, and can result in the extended structure, ‘NP-i NP-lul NP-lo V’. Second, in the structure of ‘NP-i NP-lul V’, the ‘NP-lul’ argument can be realized to the ‘NP-lo’ argument. This implies not only the formation of a new argument, but also the additional use of transitive verb. That is, the formation of ‘NP-lo’ argument results in the structure, ‘NP-i NP-lo V’, and the transitive verb obtains the use of intransitive verb. Therefore, the verb can be used as both transitive and intransitive verb. The newly generated ɵ-roles of ‘NP-lo’ include direction, goal, result, qualification, instrument, and so on. Most ɵ-roles such as direction, result, qualification, and instrument belong to the first case, and the argument of goal is the only element in the second case. Therefore, it is believed that the argument structure have been generally extended by the formation of ‘NP-lo’ argument.
