Language is a medium of communication which shows the rich cultural uniqueness of the people. The paper extracts variables or factors responsible for Yoruba language endangerment. Three hundred and sixty (360) questionnaires were distributed to Teachers of Yoruba language in secondary schools, tertiary institutions in some parts of Ondo, Ekiti, Osun, Oyo, Ogun and Lagos States and residents who are indigenes of Yoruba speaking states. Out of 360 questionnaires, three hundred and nine (309) were administered and returned. Thus, a response rate of 85.8% was achieved. A dataset was generated from the responses. Gain Ratio and ReliefF evaluation techniques using WEKA 3.7 were used to extract factors or variables after which a threshold was set and the common factor(s) of the results were selected as significant factors to actually determine variables or factors that are responsible for Yoruba language extinction. Microsoft Excel was also used to depict the data presentation of the data collected. The result shows that Lack of commitment to indigenous language, habitat displacement, colonial legacy, devastating ferocious diseases and defective language planning are factors responsible for Yoruba language extinction. It is hereby recommended that parents should be committed to the use of Yoruba as a medium of communication at home, people should erase the thought of the legacy laid by the colonial and start using Yoruba as the major means of communication and also, there should be a standard language planning by the government of Nigeria to make our indigenous languages very compulsory for all, as one of the major requirements for admission into post primary schools.

Keywords: Language Endangerment, Extraction Techniques, WEKA, Gain Ratio, ReliefF, Extinction.
