This study aims to explore the assimilation and germination phenomenon of words having "/n/". The auto segment-al Theory of (Goldsmith,1976) is used as a theoretical framework. (Alkumet, 2020) have elaborated‘Auto segment-al theory that phonetics presentation is an aggregation of supra-segment-al parts of speech, which have some initial problem of how the multiple levels of sequences can be related or linked. This research shows that "/n/" in words having "/n/" and "/b/" combination at the word middle level tend to assimilate into "/m/", but the combination remains intact at word initial and final level and germination of "/n/" is speaker-dependent. Celata, Calamai, Ricci, and Bertini (2013) have manifested the role of style and placement of phoneme in a word is crucial for a sound to get assimilated. It has been elucidated that groups of people sharing the same cultural schema and level of education tend to speak differently.
