fallacy of ambiguity
A fallacy that works only because a word or sentence can be read two ways.
A fallacy of ambiguity depends on a shift between two meanings, either of a single word (equivocation) or of a sentence's grammatical structure (amphiboly). With one meaning held fixed, the argument falls apart.
Examples
Equivocation and amphiboly are the two fallacies of ambiguity in this course.
