I'd love an expert opinion on how to interpret "as long as" and "so long as" when doing logic (specifically, whether it's considered a necessary or sufficient conditional indicator).
Also, I'd appreciate advice on how knowing when those terms are not used as conditionals.
"As long as I live, I'll love you"
"John can join us so long as he doesn't smell"
"As long as you keep hitting people, you won't make any friends"
"So long as you're here, you might as well stay at my place"
Thank you in advance!
