Every language has unique qualities. The objective of this research was to analyze the morphological structure of Southern Leyteñong binisaja. In this study, the researcher employed two different types of instruments in a descriptive design. The researchers recruited 150 volunteers for this investigation. Participants must be literate, local residents, and at least sixty years old. The findings showed the language of Southern Leyte is divided into free morpheme or root word and non-free morpheme or suffix. There are simple words or root words only. There are also morphemes called independent. There exist three types of suffixes: derivational, verb, and noun. Three word structures were found in the Southern Leyte terminologies that were collected. It is repetitive, simple, and suffixed. There were three types of morphophonemic changes in the languages of the southern Leyte. These were omission of phonemes, phonemic change and metathesis. Certain phonemes were omitted without altering the meaning, while other phonemes were substituted without altering the meaning, for example /j-y/, /a-u/, /d-m/, /h-r/, /r-d/, /l-y/, /m-b/, /k-l/, /t-w/, /k-h/, /l-p/, /m-n/, /u-i/, /i-a/, /s-l/, /n-r/, and /t-s/. Another morphophonemic change was metathesis, which involved changing in the positioning phonemes around in words. The morphological analysis of Southern Leyteñong binisaja demonstrates that the region has a distinct characteristic. It was suggested that the completed study will aid Southern Leyte residents in comprehending the distinctive qualities of their dialect. Furthermore, rather than being affected by the roots of their own language, the majority of millennials today are influenced by dynamic words. In connection to this, the researchers proposed that there must be another study that should focus on the awareness on first language vocabulary among millennials and other younger generations.
