What does meters per second per second mean?

I googled this but I still don’t get it. I’m not mathematics inclined at all so literally make this a ELI5!

A thing is going 5 m/s. That’s a speed of 5 meters per second

A second later, its speed is now 10 m/s.

After another second, its speed is 15 m/s.

After another second, its speed is 20 m/s.

So it looks like for every second of time, the speed goes up by 5 m/s, right? That means the thing is accelerating, with an acceleration of 5 m/s per second. Aka the speed is changing by 5 meters per second, per second.
