Fallacies of ambiguity appear to support their conclusions only due to their imprecise use of language. Once terms are clarified, fallacies of ambiguity are exposed. It is to avoid fallacies of this type that philosophers often carefully define their terms before launching into an argument.


The accent fallacy, and the fallacy of equivocation, are classic examples of fallacies of ambiguity. Equivocation is particularly important to look out for in evaluating philosophical arguments.
