Autological word

An autological word is a word that possesses the property it describes. In other words, an autological word is a word that is true of itself. For example, the word "short" is autological because it is a short word. Other examples include "English," which is an English word, and "noun," which is a noun. This contrasts with heterological words, which do not have the property they describe, such as "long," which is not a long word.
