Lapalissade

Lapalissade is a fancy word that means stating the obvious or saying something that is so obvious that it doesn't really need to be said. It's like when you're playing hide-and-seek with your friends and someone shouts, "I found you!" even though it's obvious that they've found you because you're standing right in front of them.

An example of lapalissade would be if someone said, "Water is wet." Well, duh! Of course water is wet! That's so obvious that it's almost silly to mention.

So, when people use the word lapalissade, they're basically saying that something is so obvious that it's almost funny or pointless to even say it. It's like stating the obvious just for the sake of stating it.
