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.
