The OED online has a "Lost for words?" button that gives you a random entry. I spent some time clicking through it over the weekend. Here are three interesting things it came up with:
- The etymology of cereal: from the Latin Cerealis, meaning pertaining to Ceres, the goddess of agriculture.
- The definition of orography: The study or description of mountains; the branch of physical geography concerned with the formation and features of mountains.
- The definition of palmiped: n. A web-footed bird. adj. Web-footed. Palmiped is classical Latin for web-footed.
