To learn correctly how irregular verbs conjugate is one of the most important items which must be acquired by learners of Korean. Although a great deal of study has been made on irregular verbs, lots of problems seem to be remaining unsolved or even undescribed. The purpose of this paper is: (1) to give a definition of irregular conjugation of Korean from pedagogical point of view; (2) to describe an appearance of irregular verbs in the spoken and written context; (3) to show appropriate explanation how irregular verbs conjugate.

This study investigated the lexical access processing of inflected Korean verbs in the mental lexicon. In Korean, verbs can be classified into two main types of inflections, which are regular and irregular inflections, which can be further divided into three types of regular inflections and two types of irregular inflections. A masked priming lexical decision task was used and the priming effects were compared. Experiments were carried out using the five different types of verbal inflections in Korean: (1) No change-regularity (regular verbs with no orthographical or phonological changes), (2) Phonological change-regularity (regular verbs with phonological changes to the stem only), (3) Orthographical change-regularity (regular verbs that only undergo orthographical changes), (4) Stem change-irregularity (the stem is omitted or alternated with the other phoneme of the stem in irregular verbs), (5) Ending change-irregularity (irregular verbs with changes in the endings by phoneme substitution). The first three types are regarded as regular verbal inflections whereas the latter two types are regarded as irregular verbal inflections. The infinitive forms of the verb were presented as target words and three different conditions were presented as prime words. The three conditions included regular verbal inflection, irregular verbal inflection, and a control condition in which morphologically and semantically unrelated primes were presented. In addition, different stimulus onset asynchrony (SOA) were manipulated (43ms, 72ms, 230ms) to examine the time frame of the morphological decomposition process in word recognition. The results revealed that there were significant priming effects in all three SOAs across conditions. Hence, there was no significant differences in priming effects between regular and irregular verbal inflection conditions. This may suggest that Korean verb processing does not adopt different processing routes for regular and irregular inflections, which can also be an indication of earlier morphological information processing for Korean verbs.

This paper explores to identify the stem-final consonants of p- and t-irregular verbs in Korean within the framework of Government Phonology. Since the advent of Generative Phonology, the phenomenon of irregular verbal conjugation has been of great interest to Korean phonologists both in linear and non-linear approaches. When we examine these analyses, we find that one of the major issues concerns the identities of the stem-final consonants of p- and t-irregular verbs. The proposals concerning this issue vary considerably from one another. In this paper, I put forward a different view from those proposals in that the stem-fmal consonants of p- and tirregular verbs are tensed p' and t' respectively.

This research was investigate to understand how moderate bilingual subjects represent the lexicon in second language. Although most researches have focused only on high proficient bilinguals, we analysed how moderate bilinguals who have learned English mostly in school represent the prototype of verb and its inflected form of verb. Results of lexical decision task showed that moderate bilingual subjects used different mental representation depending on whether the verb have regular or irregular conjugation. With regular verbs, the identification of an inflected form was affected by both the frequency of its prototype and that of inflected form, but with irregular verbs, it is affected only by the frequency of inflected form.

한국어 형태소 분석 시스템은 형태소를 분리하거나 원형을 복원하는 후보 생성 과정에서 많은 후보를 생성하고 이에 대한 사전의 검색이 요구되는 부담이 있다. 특히, 불규칙 활용 어절을 분석하려면 불규칙 활용 어절뿐만 아니라 체언 어절이나 불규칙 활용이 일어나지 않은 모든 어절에 대해서도 불규칙 어절일 가능성을 검사하고, 원형을 복원하기 위해 원형의 후보들을 역으로 추정한 후에, 각 후보에 대해 사전을 검색하는 과정을 거치게 된다. 이 때 불규칙 활용 가능성으로 인한 후보들의 과다한 생성은 사전 검색 횟수의 증가를 유발하여 시스템의 성능을 저하시키는 요인이 되어 왔다. 본 논문에서는 한글의 음절 특성을 이용하여 불규칙 활용이 일어난 후보 어절의 수를 줄임으로써 사전의 검색 횟수를 적게 하고 형태소 분석 시스템의 성능을 향상시키는 방법을 제안한다.

While there is no evidence for parafoveal processing in alphabetic languages such as English and Finnish, there is some evidence that morphological information is processed in syllabic languages like Chinese. Korean writing system, Hangul, would be able to provide morphological preview benefit effects since it is an "alphabetic syllabary" which contains both alphabetic and syllabic features. This study explored morphological parafoveal preview benefit effects during reading Korean using irregular verbs, which have phonological and orthographical differences between fundamental and conjugated forms. In the Experiment, the target word was irregular conjugated form, and there were four preview conditions: identical (e.g. 구워), fundamental form (e.g. 굽다), orthographically related (e.g. 굼다), and unrelated control (e.g. 죨어). In the result of study, identical was shortest and morphological, orthographical, unrelated preview were followed. Moreover, measures of first-pass reading of morphological preview were significantly shorter than those of unrelated control preview. This results support the hypothesis of morphological preview benefit effects in Korean. The implications of the results are discussed.
