The addressee honorification marker si-marked predicate in Korean must have an honorific vocative element in Spec-Voc in order for the unchecked feature of the addressee honorification marker si on Voc to be discharged in the Spec-head relation with the vocative element in Spec-Voc in the concept of Chomsky's (1995) Minimalist Program, which induces the addressee honorification at the speech level. The unchecked feature of the addressee honorification marker si-ess-upnita/sey-yo) percolates from T to Voc. At this point, VocP is above CP, which is why addressee honorification and impersonal subject honorification cannot appear in the embedded clause in Korean. Imperatives with quantificational subjects in English can exhibit, in addition to second person pronouns, third person pronouns as well. This is because a bound element exhibits either the person feature of the partitive phrase binding second or third person pronoun, or default third person value, which is against S. Park (2020).

The present study aims to investigate the effects of the intonations on the syntactic interpretation of the interrogatives with a wh-expression in the Daegu-North Gyeongsang Korean and the Seoul metropolitan Korean. To this end, it analyzes the syntactic and prosodic structures of the interrogatives with an embedded wh-clause or a yes/no-question with an indefinite pronoun. Two types of perception tests, one with unmodified intonations and the other with transplanted intonations, were carried out to analyze the respondents’ interpretations of the three types of the interrogatives. The results of the test with unmodified intonations were as follows. First, more than 90% of the respondents chose appropriate answers to the three types of the wh-interrogatives with no statistically significant differences. Second, the respondents’ reaction times demonstrated with statistically significant differences that the processing load of wh-questions with matrix scope was heavier than that of wh questions with narrow scope or yes-no questions with an indefinite pronoun. Third, embedding verbs of the question-selecting predicate class such as gunggeumhada ‘wonder’ led to longer reaction time than those of the proposition-selecting predicate class such as saenggakada ‘think’. In addition, the results of the perception test with transplanted prosodies revealed two decisive factors. First, the interrogative-endings -ka/na were more influential factors in the respondents’ syntactic interpretations of wh-questions than the other endings such as –ko/no or the prosodies were. Second, wh-questions with such embedding verbs as saenggakada ‘think’ were interpreted in close accordance with the transplanted prosodic structures, but not so much so in the case of wh-questions with such embedding verbs as gunggeumhada ‘wonder’ irrespective of the prosody transplants.
