Image by Adrean Clark
In an online discussion a year and a half ago, an unschooling mom who's deaf asked what was the big deal about Susan Boyle, because people were excited about her appearance on Britain's Got Talent. I said her voice was really clear. There was some discussion, some later correspondence, and the mom who had asked, Adrean Clark, sent this image of the idea of a clear voice, from the point of view of a deaf artist.
Learning about abstractions is the same as learning about anything else—you build from what you know. If you know what "clear" means in reference to water, air and glass, you're a step nearer to understanding what people mean by clear thought, and clear communication.
Watch the words you use when you speak, because they're probably the words you use when you think.
Information about Adrean Clark is here, with some examples.
