Here's the Grelling-Nelson Paradox:

An adjective is autological if and only if it describes itself. For an example, noun is a noun. he word English is English, unhyphenated is unhyphenated, and pentasyllabic is pentasyllabic. An adjective is heterological if it does not describe itself. The word long is not heterological because it is a relatively short word. Other examples are hyphenated and monosyllabic.

Here's the paradox: Is heterological a heterological word? If the answer is no, heterological is autological. This leads to a contradiction, for in the case of heterological does not describe itself, and therefore must be heterological. But if the answer is yes, heterological is heterlogical, but this leads to a contradiction because it would be autological.
