The data were taken from the results of elicitation and interview with informants who are speakers from BNDT. The analysis results were presented using formal and informal methods. Based on the analysis data, it was found that there were 5 general types of derivational affixations in BNDT, namely 7 main prefixes: prefix {a{a-}, {e-}, {ma-}, {fa-}, {sa-}, {o-}, and {me-}; 15 main suffixes include suffixes {-}, {-k}, {-g}, {-isi}, {-si}, {-ini}, {-ni}, {-i}, {-f}, {-t}, {-fi}, {-ma}, {-la}, {-a}, and {-sa}; 19 confixes {a-/-}, {a-/-si}, {e-/-}, {e-/-isi}, {e-/-t}, {ma-/-}, {man-/-g}, {ma-/-ini}, {ma-/-isi}, {ma-/-i}, {fa-/-}, {fa-/-si}, {fa-/-ni}, {fo-/-i}, {fa-/-fi}, {fa-/-sa}, {fo-/-g}, {fa-/-}, and {a-/-si}; 3 types of simulfixes a-/-la}, {a-/-ta}, and {o-/-g}; and 10 types of affix combination {man-a-}, {man-e}, {man-e-/-}, {ma-mo-}, {mo-/-g-isi}, {fo-an-/-g}, {fan-e-}, {fan-a-/-si},{o-si-}, dan {o-si-/-g}.
