If You Don't Know What It's Called, Maybe You Know What It Looks Like

There are a multitude of dictionaries on the Internet. But sometimes it's not so much defining something as it is trying to come up with the right term for a thing. That's where the Visual Dictionary comes in. You can look things up visually. It begins with basic category words. After clicking on the first category, more are displayed. Then the pictures begin. I tried looking for a horse's withers. I didn't know what it was called but I found it through the Visual Dictionary.
