A shiver is a sudden movement of your body when you feel cold or scared. It's like a quick shake that runs down your spine.
You get used to hearing people say "I'm getting a chill" and it usually means they're feeling a bit cold, but if they add "and I've got the shakes," you know what they mean by shiver. It's not just about being chilly, though - sometimes we get a shiver when we see something spooky or frightening. Imagine watching a horror movie with friends and one of them lets out a little gasp and shivers at the scary part. It means their body is reacting to the fear or surprise they're feeling.
