Equivocation is a logical fallacy which arises due to ambiguous words. ‘Good’ is one such ambiguous word. Consider this example: ‘Rama is good’. ‘Rama is a teacher’. Therefore, Rama must be a good teacher. It is one thing to be a good human being and something different to be a good teacher. This difference in the meaning of the word ‘good’ is obliterated here. Hence, fallacy of equivocation arises.
