I heard someone on television (one of my favorite resources for grammar errors) use the grammar error alls, as in Alls I know is…. It’s not an error that I hear often, but it has been around for a very long time. I remember a childhood family friend saying it—and that was eons ago!
There is no alls; the standard word is all, as in All I know is that we were supposed to meet at 8:00.
