When we say something is deadly, it means it can cause someone to stop living, just like when a toy stops working when its batteries run out. Think of it like a big, strong wind that can blow a tiny leaf away. The leaf is very light and can’t fight against the wind. Some things can be like that wind, very strong and dangerous, and they can make someone not be here anymore.

Another way to think about it is like a very hot stove. When the stove is turned on, it can cook food, but if you touch it, it can hurt you really badly. A deadly thing is like touching a super hot stove without being careful. It can be very harmful.

It’s also like a story where a character has a special power that’s too strong. If they use it the wrong way, they can hurt others. So, we have to be very careful around things that are deadly. They are things we need to be cautious about, just like how we have to be careful when crossing the street.
