Is there a notable distinction between “concerning” and “regarding”, be it in tone alone?
I—a non-native—wondered about this when starting a sentence about the weather:
Regarding the weather, …
Concerning the weather, …
Four other random usage examples:
- An Essay
ConcerningRegarding Human Understanding
- Treaty Between France and Spain
- The Question
regardingconcerning the Russo-Georgian War
Aren’t all those unconditionally interchangeable?
I imagined the difference might be in context, with regarding being used when refering to something voluntarily (regards), while concerning used when somebody needs to explain oneself (concern), but I dismissed that as a wild guess with lots of examples diluting this attempt to explain.
