Not having weight or feeling very light, often used to describe objects in space where gravity does not pull them down.
Astronauts feel weightless when they are in space.
Weightless → It is formed from "weight" (from Old English "wiht", meaning heaviness or mass) and "-less" (meaning without). The word "weightless" describes a state of having no weight or being free from heaviness.
Think of being 'without' ('-less') 'heaviness' ('weight') — that's why weightless means having no weight.
