Cheong Youn. 1996. he Double Dative Case Ban in Korean. Studies in Modern Grammatical Theories 9: 97-117. This paper explores data involving sequences of two dative-marked NPs in Korean. Sometimes such sequences result in the ungrammaticality of the sentence, at least for some speakers. By examining a variety of data, I propose the Double Dative Case Ban, a ban on two consecutive NPs that receive dative case from the same verb. Furthermore, I show that the DDCB applies simultaneously to case markers like eykey, ey, kkey, hanthey. This supports the view that all of these markers should be considered to be dative case markers, regardless of the differences in their form.
