Autoantonyms

September 14, 2011

I was writing an email this morning and wanted to be sure I used egregious correctly. This is the definition I received for my query:

It can mean outstandingly bad OR remarkably good. Another example of an autoantonym, meaning words with the same spelling but different meanings. Other examples:

Cleave can mean to cling to or to split.

Fast can mean either speedy or stuck.

Sanction denotes a penalty for disobeying a law or official approval of an action.

Personne in French can mean either a person or no one.

Any others?
