Korean coordination allows non-final conjuncts to appear either without a tensed verb as in gapping (aka right-node-raising or right-peripheral ellipsis) or without a verbal tense morpheme as in bare ko-coordination. This study uses an acceptability judgment experiment designed to investigate whether tense mismatches degrade the acceptability of Korean gapping and bare ko-coordination with reference to full coordination. The experimental findings of the study indicate that tense-matched gapping is preferred over tense-mismatched gapping and that tense-matched bare ko-coordination is preferred over tense-mismatched bare ko-coordination. The results of the study also demonstrate that temporal order, whether it is sequential or reverse, does not affect the acceptability of Korean gapping and bare ko-coordination because tense-mismatched violations are symmetric so that they cause to affect all conjuncts. Overall, this study discusses how the phenomena of tense-mismatches are accounted for in full coordination, bare ko-coordination, and gapping. The tense-mismatches in these constructions are due to differences in conjunct size. The conjunct size is TP in full coordination (with two overt Ts) and bare-ko coordination (with a null T in the first conjunct and an overt T in the second conjunct), while it is vP in gapping (with an overt T in the second conjunct).

韩语间隙和裸ko协调中的时态不匹配：一项实验研究

韩语协调允许非最终连词出现，或者没有时态动词，如间隙（又名右节点提升或右外周省略）或没有动词时态语素，如 bare科-协调。本研究采用可接受性判断实验，旨在调查时态不匹配是否会降低韩语间隙和裸露的可接受性科-协调要参照全面协调。该研究的实验结果表明，时态匹配的间隙优于时态不匹配的间隙，并且时态匹配的裸露科-协调优于时态不匹配的裸露科-协调。研究结果还表明，时间顺序，无论是顺序还是倒序，都不会影响韩语间隙和裸露的可接受性。科-协调，因为时态不匹配的违规是对称的，因此它们会影响所有连词。总的来说，本研究讨论了如何在完全协调、裸露的情况下解释时态不匹配的现象。科-协调性、间隙性。这些结构中的时态不匹配是由于连词大小的差异造成的。连接尺寸是完全协调的TP（有两个明显的T）和裸露的科协调（第一个连接中为空 T，第二个连接中为明显 T），而间隙中为 vP（第二个连接中为明显 T）。
