Accent

The accent fallacy is a fallacy of ambiguity due to the different ways a word is emphasized or accented.

Example:

A member of Congress is asked by a reporter if she is in favor of the President's new missile defense system, and she responds, "I'm in favor of a missile defense system that effectively defends America."

With an emphasis on the word "favor", this remark is likely to favor the President's missile defense system. With an emphasis, instead, on the words "effectively defends", this remark is likely to be against the President's missile defense system. Aristotle's fallacy of accent allowed only a shift in which syllable is accented within a word.
