Did you know that a decelerator can be really useful in cars?

Yeah, I read that it helps slow down safely without sudden stops.

Exactly! It's great for those moments when you need to reduce speed gradually.

For sure! I think every car should have a good decelerator.

Root Explanation

Decelerator → It is formed from "de-" (meaning down or away) and "celerare" (meaning to hasten or speed). The word "decelerator" refers to a device or mechanism that reduces speed or slows down movement.

Memory Tip

Think of 'slowing down' ('de-') the 'speed' ('celerare') — that's what a decelerator does.
