Despite the increasing rate of modernity nowadays, language has always been and is still used as an ingenious device for transmitting ideologies from one generation to the other. This study documents and examines the sociolinguistic importance of greetings as a fundamental interactional ritual in Ngamambo, a Grassfields Bantu language spoken by the Mbu people in the Mezam Division of the North West Region of Cameroon (Eberhard et al., 2019). Greetings are indices of appropriate socialisation that portray the relationship between the interactants and serve as a binding fabric that holds the community together. Through an ethnographic approach, qualitative and quantitative data were obtained from forty (40) language consultants (20 adults and 20 youths) employing interview and participant observation. Thirty greeting forms were identified, recorded, and transcribed using Elan. These forms were presented and analysed within the speech act theory (Austin, 1975) and the linguistic anthropology approach, revealing their semantic implications and the circumstances surrounding the salutation. The study established that the greeting culture in Ngamambo, which expresses the relationship between the speakers and the community’s living and dead members, is declining due to modernity, Christianity, and the influence of the dominant language, English, and the specific forms reflect the Identity of the tribe and clan. The study reveals that the Ngamambo speakers use various verbal and nonverbal greeting forms determined by social factors such as age, religion, social status, and location. It documents the greeting forms in the language, which are gradually becoming endangered.
