1. A respondent who avoids giving a clear or direct answer: James, as an equivocator, was evading his mother’s questions about his homework when he said that he would be done in a minute, when, in fact, he hadn’t even started doing it!
2. Anyone who prevaricates or hedges when responding to a question: When asked directly for the politician's position on disarmament, he was a master equivocator and so he avoided presenting an honest response.
