From Faldage's link: Equivocation

Definition:

The same word is used with two different meanings. (What are all those little scribbly things, by the way?)
Now, wait just a daggoned minute; I'd always thought that, to be equivocation, it had to be with the deliberate purpose of using a word for the other meaning. But according to this, it would be equivocation if I said, for ex., bear with me while I deal with this bear.
