Usually it is uses of words, not words in themselves, that are properly called vague.

In the one defense, briefly, we accept responsibility but deny that it was bad: in the other, we admit that it was bad but don't accept full, or even any, responsibility.

After all we speak of people 'taking refuge' in vagueness -the more precise you are, in general the more likely you are to be wrong, whereas you stand a good chance of not being wrong if you make it vague enough.

The theory of truth is a series of truisms.

Fact is richer than diction.

The beginning of sense, not to say wisdom, is to realize that 'doing an action,' as used in philosophy, is a highly abstract expression--it is a stand-in used in the place of any (or almost any?) verb with a personal subject, in the same sort of way that 'thing' is a stand-in for anynoun substantive, and 'quality' a stand-in for the adjective.

Sentences are not as such either true or false.
