The Word-initial tensification of Jeollanamdo dialect

&nbsp;&nbsp;This research aims to prove the beginning, cause, phonetic environment of Word-initial tensification.<BR>&nbsp;&nbsp;Word-initial tensification originated gradually from the beginning of tension sounds to modernconsonant system. And there is possibility that Jeonnam is the birthplace of the word-initial tensification. The first evidence that suggests this can be found in that the Jeonnam tensification stage was 16C, the stage of tension sound was 14C. Secondly, there were three types of variation consisting of: the pre-existing record of tensification form, the transient form, and the hyper-correction form. These three types show that tensification already progressed to notice by speakers in Jeonnam dialect. Finally, the current Jeonnam dialect tensification appears with a high frequency.<BR>&nbsp;&nbsp;Meanwhile, the word-initial tensification environment connects with distant of place articulation. Tension sound outs with tension of larynx. If there is long distance between larynx and place articulation, that means low-economical efficiency. Back simple vowel, vowel connected with [g] as word-initial consonant, is closed by larynx therefore there were high frequent word-initial tensification.
