When you have something extra, like an extra cookie or an extra toy, that extra thing is called a spare. It’s like when you have more than you need, and you can share or save it for later. Think of it as a backup. If you have a spare pencil, it means you have another pencil just in case your first one breaks or gets lost.

Imagine your favorite blanket. You love it so much, but sometimes it gets dirty and needs a wash. If you have a spare blanket, you can use the spare one while the other is being cleaned. This way, you never have to be without a blanket.

In a game, if you have a spare life, it means you can keep playing even if you make a mistake. The spare life is there to help you continue having fun. So, a spare is like a little helper that makes sure you always have what you need, even when things don’t go as planned.
