Definition

Describing something that does not have any mass or weight.

Example

In physics, light is often considered massless because it travels at the speed of light without having mass.

Conversation

Did you know that light is considered massless?

Yeah, I've heard that before! It's fascinating how it travels so fast.

It's crazy to think about how something can be massless and still have such an impact.

I know, right? It really changes the way we understand physics.

Root Explanation

Massless → It is formed from "mass" (from Latin "massa", meaning a lump or bulk) and "-less" (meaning without). The word "massless" describes something that has no mass or weight.

Memory Tip

Think of something that is 'without' ('-less') 'mass' — that's why massless means having no mass.
