The Santa Clause viewers are only just realising why title is spelt that way and they are not happy

Get ready to completely rethink how you're spelling Santa's last name.

We've seen a fair few variations on the spelling of Santa, but is it Claus with or without an 'e'? Well, if you said the latter you're absolutely wrong.

Turns out, that spelling was popularised by the festive film starring Tim Allen and is actually a play on words.

The traditional spelling of Santa Claus, sans 'e', came from Father Christmas' Dutch name Sinter Klaas.

However, in 1994, Allen starred in the hit Disney film as Scott Calvin, a dad who causes Santa to fall off his roof on Christmas Eve and is forced to take his place.

The added 'e' in Claus in the film's title is a reference to The Santa 'Clause' that Scott agrees to when he puts on the Santa suit.

Yep, 'Clause' as in a legal clause. We honestly weren't ready to have our minds blown like that on a Monday, but here we are...

And it's safe to say that people on Twitter were just as shocked at the news, with one fan writing: "still trying to accept the fact that I’ve been unironically spelling it Santa “Clause” like the 1994 movie starring Tim Allen. not realizing it was a play on words for like my whole entire life. merry christmas."

While another added: "When I was a kid I had no idea why they called it “The Santa Clause”. I had no idea what a “clause” was, I just thought they deliberately spelled “Claus” wrong for some reason."

A third issued a PSA to anyone now aware and we would've saved ourselves a lot of embarrassment had we seen it before: "PSA: The Santa Clause has brought a lot of joy to folks since 1994, but it has also raised a generation of adults who don't know how to spell Santa's name properly. The proper spelling is Santa C-L-A-U-S."

If you spelt the name wrong, there's no reason to feel bad because, turns out, that even an English teacher was fooled by the film "The movie "The Santa Clause" has permanently ruined my spelling of Santa Claus. I didn't know it didn't have an "e" at the end until last year. I'M AN ENGLISH TEACHER."
