A description is “autological” if it describes itself. For example:

• “Short” is a short word, so it is autological.
• The phrase “excessively verbose, wordy, redundant, repetitious, repetitious, and prolix” also describes itself, so it too is autological.
• “Written in English” is written in English, so it is autological.

A description is “heterological” if it does not describe itself. For example:

• “Long” is not a long word; so it is heterological.
• “Bisyllabic” is not a bisyllabic word, so it is heterological.
• “Written in Arabic” is not written in Arabic, so it is heterological.

Now, is the word “heterological” itself heterological?
