Um, as opposed to me learning it 50 years ago? Please Register or Log in to view the hidden image! (Although, to be fair, I've "used it in anger" a number of times since).
"Says" is the third-person singular conjugation of the verb "to say." "Say" is a regular verb, with the past tense ending in D, but it is spelled irregularly: "said" instead of "sayed." No, you've got that wrong. "Je sais" means "I know." "I am" is "je suis." You should stay away from irregular verbs in French, of which there are many. They will make your head explode.
"say" when spoken is diphthong: we glide from "a" to "i", this means the "i" is pronounced like a "y" and such it is spelled accurately as "say".
In my sisters school they used to use this rhyme (Sorry if this offends anyone) Sally Anne Is Dead! They had to change it though, not because they gained sense, but because someones Mum was called Sally Anne! How convenient! But I do spell it "Says" due to my current English teacher being smart.
The Mandela Effect is a confabulation. A number of people claim to share memories of events which differ from the available evidence of those events. It is named after Nelson Mandela, the South African anti-apartheid revolutionary, because many people claim to have clear memories of his death in prison in the 1980s... yet in fact he died of illness in 2013, many years after his release from prison. He had even been the President of post-apartheid South Africa, 1994-1999!
