In the same vein, what about anyway vs anyways? Been wondering this for a while.
Anyway and anyways tend to be used interchangeably these days, but "anyway" is considered
more correct, according to American Heritage, while "
anyways" is informal or colloquial/regional. It originally was derived from "anywise" and meant "every which way It goes back to the 13th century, however.
People said it in Southern CA when I was growing up, and I was somewhat surprised to encounter the level of rancor it attracts in some circles (some people seem to think it's a new thing, never mind I'm no spring chicken, and the word is actually very old). I've even run across some people say that they immediately think someone is stupid and illiterate if they say "anyways," even in casual conversation, which means there are a disproportionately large number of such where I grew up, never mind what census data might say.
Some people will find any excuse to be nasty to others, I guess.
I wouldn't use "anyways" in formal writing, but I might in dialog or an immersive "in pov" narrative if it's what the pov character would say.
