||Yang, Sejung. (2020). Resegmentation of tense-aspect markers in Jejueo, the traditional language of Jeju island. The Linguistic Association of Korea Journal, 28(1), 65-78. Jejueo pedagogical materials reflect previous mis-analyses of the languages verbal morphology. The current study attempts to identify those errors and to offer a corrective reanalysis. Problems with traditional proposals are traced to the influence of an over-reliance on syllable structure in the use of Hangeul to spell Jejueo as well as to a disregard for phonological phenomena resulting in the mis-segmentation of verbal suffixes. The current analysis takes account of common phonological phenomena in Jejueo: re-syllabification and allomorphic variation after s (ㅅ). The proposed tense and aspectual markers are the perfective marker eos (엇), the continuative marker eoms (어ᇝ), the non-past markers eun (은) and neun (는), and the past tense marker eon (-언). This new view of morpheme segmentation enables us to better identify the intricate system of the verbal morphology in Jejueo while providing a basis for identifying other suffixal forms with which they combine.
