Morphological study on Auxiliary Verb '-bulda' in the Jeju Dialect

This study has a purpose to explain the morphological distribution and the process of phonological change of the Jeju Dialect auxiliary verb '-bulda'. Through the research process, the Jeju Dialect’s auxiliary verb '- bulda' was revealed to be a regional splitted form of a standard Korean and auxiliary verb of other regional dialects '- burida'. The results are as follows: It shows that the three Jeju Dialect's auxiliary verbs '-burida, -bulda, -bida', and all coexist. Of the four auxiliary verbs, '-bulda' has the highest utterance frequency. '-bulda' is the widest morphological distribution, but it is not the basic form of their auxiliary verb. These auxiliary verbs are combined with the adjective freely, unlike other regional dialects. Also, the verb's lexical item provision '-beorida' equivalent to these auxiliary verbs are not the old form but the new. This verb 'beorida' is equivalent to the lexical items of this the dialect 'daekida’ and ‘nebulda'. Nebulda either came out in the same period as the auxiliary verb '-bulda' or a little bit later. The three auxiliary verbs are splitted forms in this dialect. These are: '-beurida >- burida > -bulda' and '-beurida >- birida >- bida- in mutually different steps - splitted out in two ways in the Jeju Dialect. Phoneme alteration is the same as the process of the same historical alteration, as well as other regional dialects form '-buri-'.
