Autological Word

An autological word (also called homological word) is a word expressing a property which it also possesses itself (the word "short" is short, "common" is common, "noun" is a noun, "English" is English, "pentasyllabic" has five syllables, "word" is a word, "sesquipedalian" is sesquipedalian). The opposite is heterological, a word that does not apply to itself ("long" is not long, "verb" is not a verb, but rather a noun, "Englisch" is German).
