This one is quick–but interesting!

Anyway dates from 1560, though it was traditionally two words until the 1830s. And up until modern history, it was quite literally “any way.” As in, Is there any way I can help you? I’ll get there any way I can. It quite literally meant “in any manner.”

It wasn’t until 1859 that it took on the sense of “regardless” that it now often has. So, historically, no “I’m going anyway!” unless you mean “by any path.”

Yeah, pretty sure I may have used that one incorrectly at some point or another, LOL. But now we know!
