What is sudden?

Sudden means something happens fast, like a blink of an eye.

Imagine you're playing with your favorite toy, and all of a sudden, poof!, it disappears! That’s what sudden feels like. It's not slow or gradual; it's quick and surprising, just like when your friend jumps out from behind the couch to say “Boo!”

Think of a light switch. When you flip it on, the room goes from dark to bright in an instant. That’s sudden, no slow fade, just on! The same thing happens when you turn it off, all the light vanishes at once.

Or think of a pop sound, like when you open a soda can. It's not a gentle whoosh; it’s a loud and quick pop! That’s sudden, too. You didn’t see it coming, it just happened fast!

So remember: sudden is when something happens really quickly, like a blink or a pop!
