The Case of ‘As Long As’ v. ‘So Long As’
Okay, so my “fake news” post bombed. Let’s move on to real grammatical issues.
Almost everyone I hear or read uses the phrase “as long as” in the conditional sense, as in, “as long as you don’t care, neither do I.” Wrong!
The phase “as long as” is a comparison of lengths. “That building is as long as three football fields” is one example of correct usage.
“So long as” is a conditional phrase, as in “so long as you don’t care, neither do I.”
