verb intr.: To be vague or ambiguous, especially in order to mislead.
For the word "equivocate" you seem to have omitted one of the most important uses of the term, namely, the way it is used in logic. Any good Introduction to Logic will explain clearly what the fallacy of equivocation is. Briefly, it involves using a word with two different meanings in the course of an argument, so as to fallaciously conclude what does not follow. The fallacy rests on the ambiguity of a particular term.
