Did You Know?

The original word for the science of naming was "onomatology," which was adopted from French in the mid-19th century. About a century later, however, people began referring to the science as "onomastics," a term based on the Greek verb onomazein ("to name"). Like many sciences, onomastics is itself composed of special divisions. An onomastician might, for example, study personal names or place names, names of a specific region or historical period, or even the character names of a particular author, like Charles Dickens.
