Did you know?

The meaning of a word often develops from the general to the specific. For instance, deer is used in modern English to mean several related forms of an animal species, including white-tailed deer, mule deer, elk, and moose. The Old English deor, however, could refer to any animal, tame or wild, or to wild animals in general. In time, deer came to be used only for wild animals that were hunted, and then for the red deer, once widely hunted in England. From that usage the term has spread to related animals, becoming somewhat more general again.
