Fallacy of accent


The fallacy of accent is a type of ambiguity that arises when the meaning of a sentence is changed by placing an unusual prosodic stress, or when, in a written passage, it is left unclear which word the emphasis was supposed to fall on.

History

Among the thirteen types of fallacies in his book Sophistical Refutations, Aristotle lists a fallacy he calls . While the passage is considered obscure, it is commonly interpreted as referring to the ambiguity that emerges when a word can be mistaken for another by changing suprasegmental phonemes, which in Ancient Greek correspond to diacritics. Since words stripped from their diacritics do not exist in the Ancient Greek language, this notion of accent'' was troublesome for later commentators.
Whatever the interpretation, in the Aristotelian tradition the fallacy remains roughly confined to issues of lexical stress. It is only later that the fallacy came to identify shifts in prosodic stress.
