As we can see there are many antonyms for the word evolution.
Please help me choose an appropriate antonym that would modify the word leadership. I need it as I want to translate into English the following title of the article:
Cozmin Gușă about Brexit: European leadership (the requested word) will generate a chain reaction
From the link I provided I'd pick up either decline or devaluation but I'm not sure. The word regression might do the job but I'm not sure either. Is it a good fit?
In my language would be easier as the perfect antonym of the word evolution is involution but its use in English (according to the on-line dictionaries) is limited to fewer fields such as: physiology, biology, medicine, etc.
I may have an additional question about the same evolution's antonym in case we can think of a language degeneration, or the so called degeneration would actually be an evolution too? So what would be the antonym for the language evolution?
