This study attempt to investigate the pronunciation aspects of the /ㄴ ㄹ/ sequence in the neologism. To do this, a neologism list of /ㄴ ㄹ/ sequence was made and the list was from 『new word』 resource book by the National Institute of Korean language from 2000 to 2017. Then, a questionnaire survey was conducted to college students by using a neologism list.
In previous studies, regressive lateralization and the application mechanism of nasalization have been explained in several ways. There are various explanations such as phonological perspectives, the differences of speaker perception about morphological separation possibility, analogy, differences in language consciousness between generations, expansion of nasalization language consciousness. Among the various mechanisms, morphological separability and analogy are examined to find out whether the previous mechanism in morphological separability and analogy applies to new language as well or not.
An analysis of the surveys reveals several important points. First, it was found that the preference of nasalization was generally high according to morphological separation possibility based on affix classification. It is true that perception of form boundaries has some influence on the preference of nasalization and lateralization pronunciation. However, it is impossible to check whether language speakers recognize and pronounce separation possibility or not.
In addition, existing headwords and new words were compared to see if the mechanism of 'analogy' applies equally to new words. As a result, there were some new words which had same pronunciation with headwords, but there were other cases which were not consistent with standard pronunciation of existing headwords although they had the same morphological construction. In other words, it is true that the mechanism of 'analogy' are influential, but it does not apply to every new word.
The pedagogical implication of the present research is that it is a specialized study which new word was an object of study for lateralization and nasalization compared with previous researches that existing words were only studied. Some limitation was that voice data was not dealt with in this study, thus further research will be needed.
